The answer to the question is 5 -5
Answer:
- 22°F
Step-by-step explanation:
Given that :
Morning temperature = 15°F
Change in temperature = fall by 37 degree
The temperature of the end of the day:
Morning temperature + (change in temperature)
Fall by 37° = decrease in temperature by 37° = - 37°
15°F + (-37°F)
15°F - 37°F
= - 22°F
For this case, the first thing we must do is define variables.
We have then:
x: number of pens
y: number of pencils
We now write the system of inequations:

The solution to the system of inequations is given by the shaded region.
