What would be the slope intercept form for the inequality 3x-2y>5?
Answer:
y<3/2x-5/2
Step-by-step explanation:
You just have to know how to get y on one side and the rest of the problem on the other.
First you would subtract 3x from both sides, which leaves you with -2y>5-3x.
Lastly you would divide both sides by -2.
To get the final answer of y<3/2x-5/2

Both right triangles are similar.
-> Corresponding sides of similar triangles are in proportion.
[tex] \implies \: \frac{x + 6}{16} = \frac{x}{10} \\ \\ \implies \: 10(x + 6) = 16x \\ \\ \implies \: 10x + 60= 16x \\ \\ \implies \: 10x - 16x = - 60 \\ \\ \implies \: - 6x = - 60 \\ \\ \implies \: x = \frac{ - 60}{ - 6} \\ \\ \implies \: x = 10[/tex]

70 students choose to attend one of three after school activities: football, tennis or running. There are 30 boys. 13 students choose football, of which 9 are girls. 31 students choose tennis. 9 girls choose running. A student is selected at random. What is the probability this student chose running? Give your answer in its simplest form.
Answer:
9/70
Step-by-step explanation:
Given that:
70 students choose to attend one of three after school activities: football, tennis or running.
There are 30 boys. 13 students choose football, of which 9 are girls. 31 students choose tennis. 9 girls choose running.
A student is selected at random.
What is the probability this student chose running?
Since it asking for the probability of this student (randomly select) chose running. And we can see that there are 9 girls choose running.
Therefore, we also know 70 students is the total
Hence, the answer is 9/70
9/70 is in simplest form already.

(2, -4)
Step-by-step explanation:
The solution to a system of equations is always going to be the point(s) where they intersect. To solve, use substitution and find each variable, x and y. Our final answer will be a set of coordinates (x, y). To plot this system, see the help image attached.
y = -x - 2
2x - y = 8
Substitute y to find x
2x - (-x - 2) = 8
2x + x + 2 = 8
3x = 6
x = 2
Substitute x to find y
y = -(2) - 2
y = -2 - 2
y = -4
Solution: (2, -4)

Write the equation of a line that passes through the point (-5,-4) and has a slope of 1/5
Typically, linear equations are written in slope-intercept form:
[tex]y=mx+b[/tex]
m = slopeb = y-intercept (the value of y when the line crosses the y-axis)To find the equation of a line given a point and the slope:
Plug the slope into y=mx+b as mPlug the point into y=mx+b as (x,y)Solve for bPlug b back into y=mx+b along with mSolving the Question
We're given:
[tex]m=\dfrac{1}{5}[/tex]Passes through (-5,-4)[tex]y=mx+b[/tex]
⇒ Plug in the slope, [tex]\dfrac{1}{5}[/tex]:

Do comment if you have any query.
Answer:
y = m x + b is the standard form for a straight line
you have
y = 6 x + b if m = 6
Now when x = 2, y = -8 this is given
- 8 = 6 * 2 + b substituting given values
b = -8 - 12 = -20
y = 6 x -20 is the equation requested
Check;
-8 = 6 * 2 - 20
12 = 12 so this agrees

An account with a $250 balance accrues 2% annually. If no deposits or withdrawals are made, which graph can be used to determine approximately how many years will it take for the balance to be $282?
Answer:
D. Graph 4 In an account with 250$ balance that accrues 2% annually, with no deposits or withdrawals, it takes 6 years and 6 months for the balance to be 282$
Step-by-step explanation:
if the balance accrues 2% annually, then that means every year the amount increases by 100% + 2% = 102%
102%= 102/100 = 1.02
if we multiply the balance in the account with 102% or by 1.02 at the beginning of each year we will get the amount accrued at the end of the year
First year: $250 x 1.02 = $260.1
Second year: 260.1 x 1.02 = $265.302
Third year: 265.302 x 1.02 = $270.60802
we can use these points to create a graph that will help us estimate at what year the amount will be 282$

Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
Answer:
-x (x-4) (2x-49)
Step-by-step explanation:
take out -x
you then have
2x^2-57x+196
then factor the remaining
multiply number next to x^2 which is a with 196 which is c
(-57 is b)
multiply 2 with 196 which = 392
then find out what 2 factors of 392 add up to -57
they are -8 and -49
2(x-8/2)(x-49/2)=0
2(x-49/2)(x-8/2)=0

The Ruiz family is exchanging euros for US dollars. The exchange rate is 1 euro equals 1.35261 USD. Since the Ruiz family knows that USD are stated to the nearest hundredth of a dollar, they used the conversion ratio. Will this give the Ruiz family the correct
The Ruiz family using a rounded figure for exchange rate will not give the correct exchange.
Exchange rate:
1 euro = 1.35261 USD
1.35261 rounded to the nearest hundredth = 1.35
If Ruiz family is exchanging 50 euros for instance
Original exchange rate
1 euro = 1.35261 USD
50 euro = 67.6305
Rounded exchange rate:
1 euro = 1.35 USD
50 euro = 67.5 USD
Therefore, the Ruiz family using a rounded figure for exchange rate will not give the correct exchange.

For given question,
Given that CA is parallel to DB and E is the midpoint of AD.
CA is parallel to DB
CB is transversal.
∠ACB and ∠CBD are alternate interior angles.
We know that when a transversal intersects a parallel line then alternate interior angles formed are congruent.
So, ∠ACB ≅ ∠CBD ................(i)
Similarly for CA || DB and AD is transversal.
∠CAD ≅ ∠ADB ..................(ii)
Also, E is the midpoint of AD.
By definition of midpoint,

How to solve an exponential function?Let y represent the amount of frozen dinners after x years.
If a certain quantity of money can buy 940 frozen dinners this year, and it decreases by 5% every year, hence:

At the market, 2.4 pounds of peas cost
$1.68. How much does one pound of
peas cost?
$0.7
Step-by-step explanation:Given sentence:
2.4 pounds of peas cost $1.68.Writing as an equation:
[tex]\implies 2.4 \ \text{pounds} = \$1.68[/tex]
To obtain the cost per pound of peas, divide 2.4 both sides. This will convert the value on the L.H.S to 1 pound. The value obtained on the R.H.S will be the the cost (answer).
[tex]\implies \dfrac{2.4 \ \text{pounds}}{2.4} = \$\dfrac{1.68}{2.4}[/tex]

At the dance the DJ is blaring music at 110 decibels. As he fades the music, the sound level decreases about 16% every second.
How long until the sound level falls below 30 decibels? (SHOW WORK!)
Equation:_____________________
Answer: ______________________
We are given:
Initial sound Intensity: 110 dB
Rate of decreasing sound level: 16% every second
Constructing the equation:
Since the Intensity decreases by 16% of it's current value every second.
Intensity(t) = [tex]110 * (\frac{84}{100})^{t}[/tex] [where t is the time elapsed]
In this equation, we multiply the initial sound intensity by 84% (since 16% was diminished).
because we are multiplying the same value by 84%, it will keep taking that percentage of the new value, which is what we need here because the music's intensity keeps becoming 84% of the previous value.
Time at which sound level falls to 30 dB:
replacing intensity by 30 in the equation we made.
[tex]30 = 110 * (\frac{84}{100})^{t}[/tex]
[tex]\frac{3}{11} = (\frac{84}{100})^t[/tex]
taking log of both sides.
[tex]log(\frac{3}{11}) = t*log(\frac{84}{100})[/tex]
[tex]\displaystyle \frac{log(\frac{3}{11})}{log(\frac{84}{100})} = t[/tex]
t = 7.452 seconds
Answer:
Equation: [tex]y=110(0.84)^x[/tex]
(where x is the time in seconds, and y is the sound level in decibels)
Answer: The sound level falls below 30 decibels after 7.452 seconds (3 dp)
Step-by-step explanation:
We can model this as an exponential equation.
General form of an exponential equation: [tex]y=ab^x[/tex]
where:
a is the initial valueb is growth factorx is the independent variabley is the dependent variableIf b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
If the sound decreases by 16% each second, then the growth (decay) factor will be 100% - 16% = 84% → 0.84
Given:
a = 110 decibelsb = decreases by 16% each second = 0.84x = time (in seconds)y = sound level (in decibels)Substituting these values into the equation:
[tex]\implies y=110(0.84)^x[/tex]
To find how long until the sound level falls below 30 decibels, set y < 30 and solve for x:
[tex]\begin{aligned}110(0.84)^x & < 30\\\\(0.84)^x & < \dfrac{3}{11}\\\\\ln (0.84)^x & < \ln \left(\dfrac{3}{11}\right)\\\\x \ln (0.84) & < \ln \left(\dfrac{3}{11}\right)\\\\x & > \dfrac{\ln \left(\dfrac{3}{11}\right)}{\ln (0.84)}\\\\x & > 7.452008851\end{aligned}[/tex]
Therefore, the sound level falls below 30 decibels after 7.452 seconds (3 dp)
