I WILL GIVE BRAINLIEST TO WHOEVER SHOWS STEPS! THANK YOU!:))) Show all steps on how you found the answer.
For each function, what is the output of the given input?
For f (x) =4x+7, find f(4)

23

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23

f(4)=23

Step-by-step explanation:

1.f(4)=4(4)+7

2.f(4)=16+7

3.f(4)=23

hope this helps!

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
