When Aiden left his house in the morning, his cell phone battery was partially charged. The charge remaining in Aiden's battery, as a percentage, can be modeled by the equation B = -2t + 26, where t is the number of hours since Aiden left his house. What is the slope of the equation and what is its interpretation in the context of the problem?

The slope is -2

It means that the battery decreases by 2% each hour since Aiden left his house

Step-by-step explanation:

In the equation y = mx + b, m is the slope.

This equation's slope is -2, since it is the coefficient for t.

In the context of this problem, this means that the battery will decrease by 2% each hour since Aiden has left his house.

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
