a-2= 3+6a/3
=> 3(a-2)= 3+6a
=> 3a-6= 3+6a
=> -6-3=6a-3a
=> -9=3a
hence, a=-3
Given the function f(x) = 3x-7, which of the following represents f -1(x)?
-3x+7
Step-by-step explanation:
The entire function f is being multiplied by -1, -1 isn't being plugged in for x in this case.
f -1(x)= -1(3x-7)
f -1(x)= -3x+7
the table shows the gallons filled in a pool over time (ASAP)
Answer:
125, 250, 500, 625
Step-by-step explanation:
As you can see, half of the pool is 500. 2 halves would make a whole, concluding the pool is 1000. Then for the 1/8, do 1000/8. Getting 125. 1000/4 would make it 250. And then taking the 125 from the earlier division of 8 and multiplying by 5 will get you 625. Hope this helps <3
there are 35 students in art class and 57 students in dance class. Find the number of students who are either in art class or in dance class
Answer:
hope it helps you
Step-by-step explanation:
Let
A be the set of students in art class
B be the set of students in dance class
n(A) = 35
n(B) = 57
a) When 2 classes meet at different hours and n(A ∩ B) = 12 we have:
n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = 35 + 57 - 12 = 80
b) When two classes meet at the same hour we have A∩B = ∅ that is n(A ∩ B) = 0 and
n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = n(A) + n(B) = 35 + 57 = 92

Answer:
y = 5/4x + 9
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
m = 5/4
Random point (-8, -1)
y = 5/4x + b
Step 2: Find y-intercept b
-1 = 5/4(-8) + b
-1 = -10 + b
b = 9
Step 3: Write linear equation
y = 5/4x + 9

You are playing a video game. For each diamond you collect, you earn 100 points. You also earn 75 bonus points by completing the level in less than 2 minutes. You need to earn more than 1575 points to continue on to the next level. Write and solve an inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.
Answer:
The data that we have is:
For each diamond, you earn 100 points.
If you complete the level in less than 2 minutes, you earn a bonus of 75 points.
You want to earn more than 1575 points.
Now, assuming that you want to write and solve n inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.
Because you end in less than 2 minutes, then you have the bonus of 75 points.
Then the number of points as a function of d, the number of diamonds, is:
P(d) = 100*d + 75
And you want that:
P(d) > 1575
100*d + 75 > 1575
Now we can solve this for d.
100d > 1575 - 75
100d > 1500
d > 1500/100
d > 15
You must collect more than 15 diamonds.

A survey of 73 students found that 37% were in favor of raising tuition to pave new parking lots. The standard deviation of the sample proportion is 9.8%. How large a sample (to the nearest person) would be required to reduce this standard deviation to 4.7%?
Answer:
The value is [tex]n_2 = 317[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 73
The proportion that in favor of raising the tuition is [tex]\^{p} = 0.37[/tex]
The standard deviation is [tex]s_1 = 0.098[/tex]
The required standard deviation [tex]s_2 = 0.047[/tex]
Generally the requires standard deviation is mathematically represented as
[tex]s_2 = s_1 * \sqrt{\frac{n_1}{n_2} }[/tex]
=> [tex]\frac{s_2}{s_1} = \sqrt{\frac{n_1}{n_2} }[/tex]
=> [tex]\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2[/tex]
=> [tex]\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2[/tex]
=> [tex]\frac{73}{n_2} =0.2300[/tex]
=> [tex]n_2 = \frac{73}{0.2300}[/tex]
=> [tex]n_2 = 317[/tex]

Diego is buying shrimp and rice to make dinner. Shrimp
costs $6.20 per pound and rice costs $1.25 per pound.
Diego spent $10.55 buying shrimp and rice.
The relationship between pounds of shrimp s, pounds
of rice r, and the total cost is represented by the
equation 6.20s + 1.25r= 10.55.
Write an equation that makes it easy to find the number
of pounds of rice if we know the number of pounds of
shrimp purchased.
Answer:
r= (10.55−6.20s)
--------------------------
1.25
Step-by-step explanation:
Using the principle of subject of formula, we make number of pounds of rice, r the subject of the given equation. Hence, the equation would be r = (10.55 - 6.20s)/1.25
Given the expression :
6.20s + 1.25r = 10.55
Isolate 1.25r
1.25r = 10.55 - 6.20s
Divide both sides by 1.25 to isolate r
r = (10.55 - 6.20s)/1.25
Therefore, the required expression would be
r = (10.55 - 6.20s)/1.25

The perimeter of an equilateral triangle is 96 inches. If the length of each side is (2x + 6), find the value of x.
An equilateral triangle has three equal sides. Let's try to first find the actual value of each side of the triangle!
1. Let's first find the length of each side of the triangle in inches based on the information we know!96 inches is the perimeter of the triangle. The triangle has three equal sides. We can find the length of each side by dividing 96 inches by 3!
96 / 3 = 31 inches
The length of each side in the equilateral triangle is 31 inches.
2. Now, let's find x using the information we know!We know that the length of each side is 2x + 6, and we previously found that the length of each side in the equilateral triangle is 31 inches. We are trying to find x, so we can create an equation and isolate x!
31 = 2x + 6
-6 -6
25 = 2x
÷2 ÷2
12.5 = x
Yay, we just found x! That's the answer! Feel free to ask any questions if you need help. I'm not here to judge; I'm here to help. :)
