1. What are the coordinates of P and what do they mean in this context?

2. What are the coordinates of Q and what do they mean in this context?

1. P(0.25 , 1.18)

2. P(1.25 , 2.37)

Step-by-step explanation:

You have the following function:

1. The coordinates of P specify the amount of the population of the bacteria B, in thousands for a specific values of h.

By the subdivisions of the x-axis, you can conclude that the h value of the coordinate P is h = 0.25. Then you replace this value in the function to find B:

Then, after 0.25 hours there are 1.18 thousand of the bacteria B.

2. Once again, due to the subdivisions of the x-axis, you know that h, for point Q, is h = 1.15. You replace this value for B and you obtain:

Then, after 1.25 hours there are a population of 2.37 thousand of the bacteria B.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
