Chris made 4 times as many putts as Paul made at golf practice. Together, they made 60 putts. Which equation below can be used t
alukav5142 [94]

Answer:

A) 5p = 60

Step-by-step explanation:

Since Chris and Paul both made putts totaling 60 and Chris made '4 times as many as Paul', setting up an equation with one variable makes the most sense:

p = number of putts for Paul

4p = number of putts for Chris

4p + p = 60

Combine like terms: 5p = 60

Another one omg this is annoying
Alexeev081 [22]

Answer:

Correct option: first one

Step-by-step explanation:

The equation f(x) = 5x + 1 is a function, because each value of x gives only one  value of y.

Now let's find the inverse by switching f(x) by x and x by f'(x), then isolating f'(x):

x = 5f'(x) + 1

5f'(x) = x - 1

f'(x) = \frac{x - 1}{5}

The inverse f'(x) is also a function, because each value of x gives only one value of x.

So we have that both the equation and its inverse are function, therefore the correct answer is the first option.
