If h(x) = f(x) - g(x) = 2x, at what x-value will f(x) = g(x) + 20?
a) x = 20
b) x = 10
c) x = 5
d) x = 2
Answer:
B
Step-by-step explanation:
This is a neat question
f(x) - g(x) = 2x Add g(x) to both sides
f(x) = g(x) + 2x
Now you need the right hand side to have 20 added to g(x).
2x must = 20
2x = 20 Divide by 2
x = 20/2
x = 10
So the answer must be x = 10

Two bottles of honey are compared, one costs R89,99 for 530 g and the other
R59,99 for 375 g. Which bottle is cheaper? Show all your calculations. (5)
13
Answer:
The bottle that costs R59,99 for 375 g is cheaper
Step-by-step explanation:
The given costs of the bottles of honey are given as follows;
The cost of one of the bottles of honey = R89,99 for 530 g
The cost of the other bottle of honey = R59,99 for 357 g
Let 'x' represents the bottle of honey that costs R89,99 and let 'y' represent the bottle of honey that costs R59,99, we have;
The unit cost (cost per gram) for the bottle of honey, 'x', C/gₓ = R89,99/(530 g) ≈ R 0.16979/g
The unit cost (cost per gram) for the bottle of honey, 'y', [tex]C/g_y[/tex] = R59,99/(357 g) ≈ R 0.168/g
Given that the unit cost of a bottle 'y' ≈ R 0.168/g is less than the unit cost of a bottle of 'x' ≈ R 016979/g, a bottle 'y' is cheaper than the bottle 'x'
Therefore;
The bottle that costs R59,99 for 375 g is cheaper than the bottle that costs R89,99 for 530 g.
Write an equation in slope-intercept form for each line at the right. Line one goes from (-6,7) to (1,-7) and line two goes from about (1.25,7) to (3.25,-7)
y=-2x-5 and y=-7x+15.75 are equations in slope-intercept form for each line.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
We need to find equation in slope-intercept form of line passing through of (-6,7) to (1,-7) and one more line passing through (1.25,7) to (3.25,-7)
Slope of line with (-6,7) to (1,-7) is m=-7-7/1+6=-14/7
=-2
y intercept we have to find
7=-2(-6)+b
7=12+b
-5=b
So slope intercept form of line passing through (-6,7) to (1,-7) is y=-2x-5
Now Slope of line with (1.25,7) to (3.25,-7) is
m=-7-7/3.25-1.25
m=-14/2=-7
y intercept we have to find
7=-7(1.25)+b
7=-8.75+b
b=15.75
So slope intercept form of line passing through (1.25,7) to (3.25,-7) is y=-7x+15.75
Hence, y=-2x-5 and y=-7x+15.75 are equations in slope-intercept form for each line.

Rewrite this polynomial in terms of its simplest factors using the appropriate method: x2 − 3x − 18.
Use your keyboard and the keypad to enter your answer. Then click Done.
The polynomial in terms of its simplest factors is (x + 3)(x − 6)
How to rewrite the polynomial in terms of its simplest factorsFrom the question, we have the following parameters that can be used in our computation:
x2 − 3x − 18.
Rewrite as
x² − 3x − 18
Expand
x² − 3x − 18 = x² − 6x + 3x − 18
Factorize the expression
This gives
x² − 3x − 18 = x(x − 6) + 3(x − 6)
Factor out x - 6
x² − 3x − 18 = (x + 3)(x − 6)
Hence, the expression is (x + 3)(x − 6)

Answer:
311 cm squared
Step-by-step explanation:
Formulas/things to know:
area of circle = pi times r^2
diameter = r * 2
pi = 3.14159
r = radius
__________________________________________________________
CIRCLE 1:
diameter 36, radius = 36/2 = 18
area of circle = pi times 18^2
3.14159 times 324
= 1017.87601976
CIRCLE 2:
diameter 30, radius = 30/2 = 15
area of circle = pi times 15^2
3.14159 times 225
= 706.858347058
__________________________________________________________
Great, now we can calculate the difference between the areas!
1017.87601976 - 706.858347058
= 311.017672702
and then round to the nearest square centimeter: 311
answer: 311 cm squared
note: make sure to round at the end, not after calculating area for the most accurate result! :) Hope this helped

Answer:
68, 97, 81, 96, 84.2
Step-by-step explanation:
16. The minimum of the data is the smallest value. Take the smallest stem value and find its smallest leaf value, you'll get 68.
17. Take the largest stem value and find its largest leaf value. That's 97.
18. Counting the number of values, there are 10 values here. So you need to look at the mean of the 5th and 6th values. (80 + 82) ÷ 2 = 81
19. Mode: the most frequently occurring value. All values in this dataset are unique except for the two 96s in the last row, hence 96 is the mode.
20. Add all values and divide your result by the number of values.
(68+75+77+79+80+82+92+96+96+97) ÷ 10 = 84.2
Hence 84.2 is your mean.

x^2+6x+8=0 complete the square method
Answer:
x = - 2 or x = - 4
Step-by-step explanation:
Via completing the square:
x^2 + 6x + 8 = x^2 + 6x + (6/2)^2 - (6/2)^2 + 8
= (x + 3)^2 - 3^2 + 8
= (x + 3)^2 - 9 + 8
= (x + 3)^2 - 1
Since x^2+6x+8=0,
(x + 3)^2 - 1 = 0
(x + 3)^2 = 1
x + 3 = +- sqrt(1)
x + 3 = +- 1
x + 3 = 1 or x + 3 = -1
x = -2 or x = -4

Answer:
[tex]x \approx 55.8[/tex]
Step-by-step explanation:
In order to solve this problem, one must use the trigonometric ratios. These ratios are the following,
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)= \frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
Remember, each side is named relative to the angle, thus sides will attain different names depending on the angle which one sues to calculate with.
In this case, one is given the measure of the angle, and the measure of the side opposite to the angle. One is asked to find the measure of the side adjacent to the angle. Use the trigonometric ratio ([tex]tan[/tex]) to solve for the unknown. Substitute in the given values,
[tex]tan(25)=\frac{26}{x}[/tex]
Manipulate the equation such that it is solved for the parameter(x),
[tex]x=\frac{26}{tan(25)}[/tex]

What is ordinate of a 3 4?
The coordinate of 3 4 indicates a point on a cartesian plane.
What is coordinates system?In mathematics, the coordinate system refers to the method in which a location of a point is identified in the plane or space.
There are two coordinate system, one is cartesian coordinate system and the other is polar coordinate system.
Each coordinate system has some reference lines called reference axis or reference direction or point called reference direction and point.
What do we mean by coordinate of 3 4?As per the definition of a cartesian coordinate system, a location of a point is identified by a pair of numerical terms. The first one indicates the X coordinate and the second one indicates the Y coordinate.
So, the above coordinate 3 4 refers to a point on the XY coordinate system where 3 is the X coordinate and the distance from Y axis and 4 is the Y coordinate and distance from the X axis.

Subtract 15 from both sides:
2x = 130
Divide both sides by 2:
x = 65
Answer:
145 = 2x + 15
2x = 130
x = 65
145 and 2x + 15 are vertical angles and therefore congruent.

What distinguishes a hyperbola from a parabola?A set of points in a plane that are equally spaced apart from a directrix or focus are known as parabolas. The difference in distances between a group of points that are situated in a plane and two fixed points—which is a positive constant—is what is referred to as the hyperbola.
