<u>Answer:</u>

C. a horizontal shift of 9 units left

<u>Step-by-step explanation:</u>

Look at this helpful chart:

Vertical Translations

translation up k units: g(x) = f(x) + k, where k > 0

translation down k units: g(x) = f(x) – k, where k > 0

Horizontal Translations

<u>translation left k units:  g(x) = f(x + k), where k > 0</u>

translation right k units:  g(x) = f(x – k), where k > 0

The change happening in Martina's graph is therefore a horizontal translation to the left.

Answer:

B.a vertical shift of 9 units up

Step-by-step explanation:

Given f(x) = 4x-2\\g(x) = 4x+7

g (x) = f (x) + k

It means shifting f (x)\ k unit vertically.

Now, we will find the value of k for the given function

g(x) = 4x+7\\\\add\ 2\ and\ subtract\ 2\\\\g(x) = 4x+7+2-2\\g(x) = 4x-2+9\\\\We\ have\ f(x)=4x-2\\\So,\ g(x)=f(x)+9

k=9

Hence, vertical shift of 9 units.

What is 82% of 525?<br> Show work
True [87]

Answer:

430.5

Step-by-step explanation:

1. We assume, that the number 525 is 100% - because it's the output value of the task.  

2. We assume, that x is the value we are looking for.  

3. If 525 is 100%, so we can write it down as 525=100%.  

4. We know, that x is 82% of the output value, so we can write it down as x=82%.  

5. Now we have two simple equations:

1) 525=100%

2) x=82%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

525/x=100%/82%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 82% of 525

525/x=100/82

(525/x)*x=(100/82)*x       - we multiply both sides of the equation by x

525=1.219512195122*x       - we divide both sides of the equation by (1.219512195122) to get x

525/1.219512195122=x  

430.5=x  

x=430.5

now we have:  

82% of 525=430.5
