- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°

Answer:
none of the options shown
Step-by-step explanation:
You can add 2x+2 to the inequality and get ...
8 ≥ 2x
4 ≥ x . . . . . divide by 2
This means that there should be a solid circle at x=4, and shading should be to the left of that.
None of the three graphs shown here is appropriate. (We don't see Option 2.)

Attached is the output of a graphing calculator. The solid line at x=4 corresponds to a filled dot on a number line plot.
Answer:

Step-by-step explanation:
The first column is x while the second is y. To find rate, you divide y by x. If each row has the same outcome, it is proportional.
First row:
9.00÷2= 4.50
Second row:
22.50÷5= 4.50
Third row:
31.50÷7= 4.50
There is a proportional relationship based off of the values.
So B, yes there is a constant of proportionality of $4.50.
