The measures of the three angles of a triangle are given by 2x + 6, x, and 3x.
What is the measure of the largest angle?

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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
