ANSWER
A. 1/9
EXPLANATION
When we have an expression with a negative exponent we can solve it by "flipping" the fraction and solving with the positive exponent:

In this problem we have to find:

We can think of a whole number as a fraction whose denominator is 1:

So we can use the trick:

And solve:
Answer:
x≤8
Step-by-step explanation:
x÷4≤2
Take the 4*2=8 Since you are dividing on one side, you do the opposite and multiply
Answer:
90
Step-by-step explanation:
I'm not sure about the answer
Answer:
y=-1/5x+55
Step-by-step explanation:
you subtract 10-0 over -5-(-3) which will be a -2/10 = -1/5
Then you find you Y intercept by doing y-10=-1/5(x+5) = y-10=-1/5x-1=-11=-1/5x then you divide -1/5 by the -11 = 55
Answer:
The midpoint of MN is <u>(7,1)</u>
Add the x coordinates 7+7=14 then you divide that by 2 giving you 7.
Then you add the y coordinates together 6+(-4)=2 then divide by 2 and that gives you 1. Therefore the answer is (7,1)
