8 0

Answer:

Part 19) x=5

Part 20) x=-3

Step-by-step explanation:

Problem 19) Find the value of x so that f(x)=7

step 1

Find the intersection point of the given line in the graph with the line y=7

The intersection point is (5,7)

see the attached figure

therefore

The x-coordinate of the intersection point is the value of x when f(x)=7

x=5

f(5)=7

Problem 20) Find the value of x so that f(x)=7

step 1

Find the intersection point of the given line in the graph with the line y=7

The intersection point is (-3,7)

see the attached figure

therefore

The x-coordinate of the intersection point is the value of x when f(x)=7

x=-3

f(-3)=7

What does 21 equal?

The amount of milk Karim drank at breakfast plus the amount of milk Karim drank after breakfast.

21 = milk at breakfast + milk after breakfast

Let's substitute what we know into this equation:

21 = milk at breakfast + milk after breakfast

21 = 1 + m

Now that we have our equation, let's solve.

21 = 1 + m

-1    -1

20 = m

Therefore, Karim drank 20 cups of milk after breakfast.
