Evaluate f(x) = 2x - 7 when x = 4.

Step-by-step explanation:

f(x) = 2x - 7

when x = 4

It means that equate f(x) to the value of x that's 4 and solve for x

That's

f(x) = 4

We have

Add 7 to both sides of the equation

Divide both sides by 2

We have the final answer as

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

let x be the amount she saves each month.

your final answer is x ≥

hope this !
