If f(x) is a linear function, f(−2)=4, and f(1)=−1, find an equation for f(x)

Step-by-step explanation:

Given

Required

The equation of the function

The given parameters means that:

Calculate the slope (m)

The equation is then calculated using:

This gives:

Open bracket

Take LCM

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

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
