What is the inverse of the function 9y - 6 = 3x ?

IgorC [24]

Answer:

Option (2)

Step-by-step explanation:

Given function is,

9y - 6 = 3x

y = $\frac{3x+6}{9}$

To find the inverse of the given function,

1). Substitute x in place of y and y in place of x.

x = $\frac{3y+6}{9}$

2). Now we have to solve this equation for the value of y.

9x = 3y + 6

3y = 9x - 6

y = (3x - 2)

Therefore, inverse of the given function is y = (3x - 2)

Option (2) will be the answer.

Ali’s wage was increased from 120$ to 132$ per week. find the increase as fraction on its simplest form, as a percentage of the

Anettt [7]

Well the increase is 132/120. Simplify by dividing 12 from the numerator and the denominator, you should get 11/10.
11/10 is also 110%

What is the answer to 4|x-1|=12

STatiana [176]

Answer:

(4,0) and (- 2,0): Answer

Step-by-step explanation:

Absolute value questions have two essential steps.

1. Solve the equation as it is written.

2. Solve it changing the sign of the right hand side. I will include a graph to confirm my answer

4*abs(x - 1) = 12 Divide by 4

abs(x - 1) = 12/4
abs(x - 1) = 3 Equate this to 3
x - 1 = 3 Add 1 to both sides
x - 1 + 1 = 3 + 1 Combine
x = 4

4*abs(x - 1) = - 12 Divide by 4

abs(x - 1) = - 12/4
abs(x - 1) = - 3
x - 1 = - 3 Add 1 to both sides
x - 1 + 1 = -3 + 1
x = - 2

So this has 2 answers

(4,0) and (- 2,0)

Korey runs every 3rd day and swims every 4th day. If he runs and swims today, how many days will it be before Korey runs and swi

hichkok12 [17]

Answer: 12 days

Step-by-step explanation:

Based on the question, we have to list the multiples of 3 and 4. This will be:

3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40.

The lowest common multiple is 12.

It will take 12 days before Korey runs and swims again on the same day.

Please help!! Math problem and I don't know how to do it!! 14 points!!

Let Brian's steps have a measure of 1, and Richard's steps have a measure of k. Then after each walks 5 steps away from the other, their distance apart is

... 5 + 5k

We are told that distance is equal to 9 of Richard's steps, so is equal to 9k.

... 5 + 5k = 9k

... 5 = 4k . . . . . . . subtract 5k

... 5/4 = k . . . . . . divide by 4

Richard's steps are 5/4 the size of Brian's steps. The appropriate selection is

... b) 5/4
