What is the y-intercept of the function f(2)=4-5x?
-5
-4
4
5

C. 4

First, rearrange the equation into slope intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. You get y = -5x + 4. This means the y-intercept is 4.

For this case we have a function of the form

Where:

To find the y-intercept of the function we must do x = 0.

Then, replacing:

So, the y-intercep of the function is 4

Option C

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

125 yards

step-by-step explanation:

i take 75 plus 50.
