Answer:
Step-by-step explanation:
<u>This is a linear relationship y= mx + b and:</u>
- The y-intercept is b = 12.60
- The slope is m = 0.64
<u>The monthly total is:</u>
Answer:
<u>Given:</u>
- 2x + 9 < 0 ⇒ 2x < - 9 ⇒ x < - 4.5
- x > -12
<u>Combined we have:</u>
<u>The integers in the same interval are:</u>
- x ∈ {-11, -10, -9, -8, -7, -6, -5}
