Answer:

(0, 9 ) and (- 4, 1 )

Step-by-step explanation:

To determine which ordered pairs lie on the graph substitute the x- coordinate of the point into the right side of the equation and compare the value obtained with the y- coordinate

(- 20, - 49 )

2x + 9 = (2 × - 20) + 9 = - 40 + 9 = - 31 ≠ - 49

(1, 10 )

2x + 9 = (2 × 1) + 9 = 2 + 9 = 11 ≠ 10

(0, 9 )

2x + 9 = (2 × 0) + 9 = 0 + 9 = 9 ← point lies on graph

(- 4, 1 )

2x + 9 = (2 × - 4) + 9 = - 8 + 9 = 1 ← point lies on graph

(- 3, 40 )

2x + 9 = ( 2 × - 3) + 9 = - 6 + 9 = 3 ≠ 40

Step-by-step explanation:

We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.

First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:

$\text{Amount of total ribbon in inches}=11\times 18\text{ inches}$
