I need help with questions 1 and 2.

1. The integer is +5000.

2. The integer is -4.

Solution:

To write an integer that represents the given situation:

1. A plane flies at an altitude of 5000 feet.

Here, the distance between ground and plane is mentioned.

Plane is above the ground. So, it is positive integer.

The integer is +5000.

2. A swimmer is 4 feet below the surface of the water.

Here, also mentioned the distance between surface of water to swimmer.

But, it is below the ground. So, it is negative integer.

The integer is -4.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
