Answer:

Step-by-step explanation:

No of teachers in the school = 5

Salaries they make =40000 to 70000

When one of the five teachers reduce salary to 20000/- per year, median may or may not shift one number to the left

Mean will definitely decrease by difference/5 = 4000 dollars

Thus mean will defintely change by reduction of 4000 dollars.

Median has a chance to remain the same or may shift left side one item.

Suppose f(x) = x. Find the graph of f(x+2).
Ostrovityanka [42]
<h2>Hello!</h2>

The answer is:

The fourth graph.

<h2>Why?</h2>

We are given the following equation:

f(x)=x

Then, we need to find the graph of f(x+2) that will be equal to:

f(x+2)=x+2

y=x+2

Now, finding the x-axis interception, making "y" equal to 0, we have:

0=x+2

-2=x

Therefore, the x-axis interception point is located at (-2,0), it matches with the fourth graph.

Now, finding the y-axis interception, making "x" equal to 0, we have:

y=x+2

y=0+2=2

Therefore, the y-axis interception point is located at (0,2), it matches with the fourth graph.

Hence, we have that the graph of f(x+2) is the fourth graph since the second graph function cuts the x-axis at -2 and the y-axis at 2.

Have a nice day!

Answer:

a^2b^7

Step-by-step explanation:

dividing exponents is basically subtracting the top exponent by the bottom. So, 3 - 1 = 2, thus giving you a^2, and 9 - 2 = 7, giving you b^7
