Answer: (0,1), (1,0)
Step-by-step explanation:
plug in a number for y.
ex) x=0 y=1
y=-x + 1
1= -0 + 1
1=0 + 1
Remember you can do anythingn to an equation as long as you do it to both sides
2-5x=-18
minus 2 both sides
2-2-5x=-18-2
0-5x=-20
-5x=-20
times both sides by -1
5x=20
divide both sides by 5
(5x)/5=20/5
(5/5)x=4
1x=4
x=4
Answer:
122 degrees
Step-by-step explanation:
<em><u>*A pentagon has a total of 540degrees </u></em>
1st step: take all of the degrees and add them up:

2nd step: subtract the sum from 540:
540 - 418 = 122
The missing angle is 122 degrees
