buying a membership card and paying each time looks like this: 20 + 2x where x is the number of times you go to the gym. 20 dollars base then 2 each time you go.

4 each time you go is just 4x

so just set the two equal to each other.

20 + 2x = 4x

If you solve it you will get x = something, which would be the number of times to make the two equal.

Simplify each expression as much as possible, and rationalize denominators when applicable. 4x. √64x^2=?

Monica [59]

Answer:

$24x^{2}$

Step-by-step explanation:

We have

$4x\sqrt{64x^{2}$ We can root the 64 and the $x^{2}$

Then we get:

$4x8x$ Now we multiply and get

$24x^{2}$

What is the equation represented by the order pairs {(0,32),(1,16),(2,8),(3,4)}?

bagirrra123 [75]

Answer:

The equation represented by the ordered pair is;

y = 2^(5-x)

Step-by-step explanation:

Here, we want to write the equation represented by the ordered pairs

From what we have in the question, we can see that while the x-values increase in arithmetic progression of 1

The y-values decrease in order of two geometrically

Thus, the equation is;

y = 2^(5-x)
