URGENT STAMPS Zoe added 23 tamps to her
collection., Three months later her
collection had tripled in number to a
total of 159 stamps. How many stamps
did Zoe have to start her collection?
Answer:
30
Step-by-step explanation:
x = original number of stamps
x+23 (added 23 stamps to the collection)
3(x+23) tripled in number
3(x+23) = 159
Divide each side by 3
3(x+23)/3 = 159/3
x+23=53
Subtract 23 from each side
x+23-23 = 53-23
x = 30

Does anyone know how to solve |4x+3|-9<5
Answer in fraction form: -17/4 < x < 11/4
Answer in decimal form: -4.25 < x < 2.75
=======================================================
Work Shown:
|4x+3| - 9 < 5
|4x+3| < 5+9 .... adding 9 to both sides
|4x+3| < 14
-14 < 4x+3 < 14 .... see note at the bottom
-14-3 < 4x < 14-3 .... subtracting 3 from all sides
-17 < 4x < 11
-17/4 < x < 11/4 .... divide all sides by 4
-4.25 < x < 2.75
This says that x is between -4.25 and 2.75, but x is not equal to either endpoint.
Note: I used the rule that |x| < k becomes -k < x < k where k is a positive real number.
What is the relationship between the number of sides in a regular polygon and
number of lines of symmetry?
Answer:
Divide 360 by the difference of the angle and 180 degrees. For example, 360 divided by 15 equals 24, which is the number of sides of the polygon. Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.

Answer:
Below.
Step-by-step explanation:
(a) Over the first 5 seconds rate of change of speed
= (9-1)/5
= 8/5
= 1.6m/s^2
(b) (21-9)/16-t) = 2
12/16-t = 2
32 - 2t = 12
32 - 12 = 2t
20 = 2t
t = 10 seconds
Step-by-step explanation:
Total Time Taken = 16secs
10a). We're asked to calculate the rate of speed change for the first 5secs.
This is another way of saying "Calculate Acceleration" in the first 5sec of Motion.
Why?
Acceleration is the rate of change of speed or the rate at which speed changes.
acceleration = v - u/t
where v = Final Speed
u = initial Speed.
Looking at the graph
You see that
Initial speed(u) = 1m/s
Final Speed(v) = 9m/s
t = 5secs
Acceleration = 9 - 1/ 5
a = 8/5
a = 1.6m/s².✅
10b)
We're asked to calc "t" from the graph.
Given that the acceleration at "t" untill 16sec(end of motion) is 2m/s².
This simply means that Constant Acceleration was held from "t" to the end of the Motion.
Do not confuse Constant Acceleration for Constant Velocity.
At Constant Velocity... Acceleration is zero(0)
At Constant Acceleration...Velocity Changes Uniformly or at the same rate each second and this is what we're dealing with in this question.
Taking the same step as we used in calculating acceleration above
Given a= 2m/s²
a = v - u/∆t
Where ∆t means time change or difference.
From "t" to 16
The change in time is 16 - "t"
2 = 21 - 9/( 16 - t)
2 = 12/16-t
16-t = 12/2
16 - t = 6
t = 16 - 6
t = 10secs.✅

An ant walk about 3 inches per second how many miles per day could an ant travel if it walked without a break?
Answer:
Step-by-step explanation:
45/11 miles per day or ~4.091 miles per day
Step-by-step explanation:
3 inches per second
24 hours in a day
60 minutes in 1 hour
60 seconds in 1 minute
Amount of inches per minute: 3 x 60 = 180 inches
Amount of inches per hour: 180 x 60 = 10,800 inches
Amount of inches per day 10,800 x 24 = 259,200 inches
To find the number of feet that 259,200 inches is, divide by 12.
259,200/12 = 21,600 feet per day
To find the number of miles that 21,600 feet is, divide by 5280.
21,600/5280 = 45/11 = 4.09090909091 = ~ 4.091
So, an ant could walk 45/11 miles per day or ~4.091 miles per day if it walked without taking a break.

Answer:
3
Step-by-step explanation:
A algebraic transformation is represented by
[tex]a(bx - h) + k[/tex]
where a is the vertical compression or stretch. a is also the vertical reflection if value is negative . B is the horizontal compression or stretch it is also a horizontal reflection if it value is negative. h is the horizontal shift. And k is the vertical shift.
3 replaces k in this scenario for the vertical translation so 3 is the answer.

Y= 0.5x + 2 showing on the graph
Answer:
Y is output, x is input
Step-by-step explanation:
I. Given x is -1, 0, 1
II. Perform x in linear equation
If x is -1
y = 0.5(-1) + 2
y = 1.5
=> (-1, 1.5) -1 is x, 1.5 is y
If x is 0
y = 0.5(0) + 2
y = 2
=> (0, 2) 0 is x, 2 is y
If x is 1
y = 0.5(1) + 2
y = 2.5
=> (1, 2.5) 1 is x, 2.5 is y
III. Perform (x, y) in graph, there will be something like this

Number of units
(y) 2 52 102 152 202 252 302 352 402 452
Part A: Is there any correlation between the number of workers in a factory and the number of units produced daily? Justify your answer. (4 points)
Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate? (3 points)
Answer:
Part A: Yes. There is a correlation between the number of workers in a factory and the number of units produced daily.
Part B: The equation of the function that best fits the data is
Part C: The slope is which indicates the rate of change of number of units produced daily over the change in number of workers. The y - intercept is which indicates the number of units produced by number of workers.
Explanation:
Part A: To determine the correlation coefficient, first we shall find the slope and y - intercept.
Let us substitute the coordinates and in the slope formula, to find the value of slope.
Hence, we have,
Thus, the slope is
The y - intercept is the value of y when the value of x is equal to 0.
Thus, from the table , we can see that when , the value of y is 2
Hence, the y - intercept is
Substituting the values and in the slope intercept form , we get,
Hence, there is a linear correlation between the number of workers in a factory and the number of units produced daily.
Part B: To find the function that best fits the data, let us substitute the value of slope and y - intercept in the slope intercept formula.
Since, we have already found slope and y - intercept
Substituting these values in the slope intercept form , we get,
Thus, the function that best fits the data is
Part C:
The slope is
The slope indicates that the rate of change of number of units produced daily over the change in number of workers.
The y - intercept is
The y - intercept indicates that the number of units produced by number of workers.
Step-by-step explanation:
A. Yes. B. A linear function of the form y = 5x + 2 can best fit the data. C. The slope (m) of the plot indicates the rate of change in the number of units produced per worker. The y-intercept (b) indicates the number of units produced when there are zero workers.
What is the Linear function?A linear function is defined as an equation in which the highest exponent of the variable is always one.
Part A:
Yes, there is a positive correlation between the number of workers in a factory and the number of units produced daily. As the number of workers increases, the number of units produced also increases.
Part B:
A linear function of the form y = 5x + 2 can best fit the data, which is determined by the two points (10, 52) and (50, 252).
Part C:
The slope of the plot indicates the rate of change in the number of units produced per worker. The y-intercept indicates the number of units produced when there are zero workers. The slope and y-intercept together describe the overall trend of the data and can be used to make predictions about future production levels.

In the figure MX = NY

i) Are the sides of ∠MPX equal to the sides of ∠NPY ?
ii) what is the special about the postion of P on MN
Answer:
i) yes
ii) it splits MN in half (bisector)
Step-by-step explanation:
We are given that MX and NY are parallel. This means, due to alternate interior angles, <XMN and <YNM are congruent as well as <MXY and <NYX. We are also given MX = NY. This is enough information to prove ΔMPX is congruent to ΔNPY due to ASA(two angles and a side between them).
(i) Now, because of this, we can say that all the sides of ΔMPX are congruent to those of ΔNPY. And, this means MP = NP. Since the point P divides the segment MN into two equal pieces, it's a bisector of MN(splits it in half).

Answer:
£ [tex]36[/tex]
Step-by-step explanation:
In this situation, the price of an item is (£ [tex]45[/tex]). It is given that there is a ([tex]\frac{1}{5}[/tex]) off discount on this item. To find the price of this item, one will have to subtract the discount rate from (1), this will yield the fraction of the object price that one has to pay. To find the actual amount one has to pay, one must multiply the fractional price of the object by the original price of the object. Using this line of thought, one can form the following equation:
[tex](1-(rate\ of\ discount))(original\ price)=sale\ price[/tex]
Substitute the given values into this equation:
[tex](1-\frac{1}{5})(45)=sale\ price[/tex]
Simplify: remember, a fraction with any number over itself equals (1). Bear in mind that one can only perform operations such as addition and subtraction between fractions with common denominators, that is the number under the fraction bar.
[tex](1-\frac{1}{5})(45)=sale\ price[/tex]
[tex](\frac{5}{5}-\frac{1}{5})(45)=sale\ price[/tex]
[tex](\frac{5-1}{5})(45)=sale\ price[/tex]
[tex](\frac{4}{5})(45)=sale\ price[/tex]
Now perform the multiplication. Divide the denominator by the number one is multiplying by, then multiply it by the numerator (number over the fraction bar).
[tex](\frac{4}{5})(45)=sale\ price[/tex]
[tex](4)(45 / 5)=sale\ price[/tex]
[tex](4)(9)=sale\ price[/tex]
[tex]36=sale\ price[/tex]

Why do you keep sending the same question over and over again?
Step-by-step explanation:
Total Time Taken = 16secs
10a). We're asked to calculate the rate of speed change for the first 5secs.
This is another way of saying "Calculate Acceleration" in the first 5sec of Motion.
Why?
Acceleration is the rate of change of speed or the rate at which speed changes.
acceleration = v - u/t
where v = Final Speed
u = initial Speed.
Looking at the graph
You see that
Initial speed(u) = 1m/s
Final Speed(v) = 9m/s
t = 5secs
Acceleration = 9 - 1/ 5
a = 8/5
a = 1.6m/s².✅
10b)
We're asked to calc "t" from the graph.
Given that the acceleration at "t" untill 16sec(end of motion) is 2m/s².
This simply means that Constant Acceleration was held from "t" to the end of the Motion.
Do not confuse Constant Acceleration for Constant Velocity.
At Constant Velocity... Acceleration is zero(0)
At Constant Acceleration...Velocity Changes Uniformly or at the same rate each second and this is what we're dealing with in this question.
Taking the same step as we used in calculating acceleration above
Given a= 2m/s²
a = v - u/∆t
Where ∆t means time change or difference.
From "t" to 16
The change in time is 16 - "t"
2 = 21 - 9/( 16 - t)
2 = 12/16-t
16-t = 12/2
16 - t = 6
t = 16 - 6
t = 10secs.✅
