Which answer shows y-3x< -x+4, rewritten to isolate y, and its graph a. y < 4x + 4 b. y < 2x + 4

We are given inequality : y-3x<-x+4.

We need to isolate it for y on left side.

In order to isolate it for y, we need to get rid -3x from left side.

3x is being subtracted from left side.

The reverse operation of subtraction is addition.

Adding 3x on both sides, we get

y-3x+3x<-x+3x+4.

y < 2x+4

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.
