Write a function rule for the table
Ghella [55]

Answer:

D.

Step-by-step explanation:

Recall the slope is change of y over change of x which in this case the change in x is 1 while the change in y is 2 since the y's are going up by 2 while the x's are going up by 1.

So the slope is 2.

The one equation with slope 2 is D.

The answer is most likely D.

Let's check.

f(x)=2x

y=2x

y=2(-3)=-6 while x=-3.

y=2(-2)=-4 while x=-2.

y=2(-1)=-2 while x=-1.

y=2(0)=0 while x=0.

Also notice the x is doubled (multiplied by 2) to get y.

If 9% of a number equals 5, find 36% of that number.
lakkis [162]

Answer:

20

Step-by-step explanation:

  1. You can set this up in an algebraic equation:
  2. .09x=5  which translates to 9% times a variable or unknown number equals 5
  3. Divide both sides by .09 which turns to 55.5
  4. Multiply by .36 to find 36% of that number which equals 20
