Supplementary because the line equals 180°
(x-21)+x
2x-21=180
2x=201
×=100.5°
Multiplication bc... do you know all I know is its multiplication
We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2
So the solution of this system of equation is the coordinate (1, -2)
Answer:
9z+11
Step-by-step explanation:
7z+8+2z+3
CLT, or combine like terms.
7z+2z=9z
8+3=11
So the simplified version is 9z+11.
