A system of equations is shown.
y=-2x+3
y= 22
What are the solutions to the system of equations?

x=-9.5

Step-by-step explanation:

y=-2x+3

y=22

Substitute the value of y into the given equation

22=-2x+3

Substrate 3 from both sides

19=-2x

Divide both sides by-2

x=-9.5

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
