Answer:
5+9=9+5
Step-by-step explanation:
Because ethier way it will be 14, but idl dont take my word yet...
Y is gonna equal -1 and X is gonna be 3
X=62
Vertically opposite angles are equal
Y=44
Angles on a straight line add up to 180
Z =286
Because
180-x-y=74
360-74=286
Answer:
x=2 and y=-6 aka. (2,-6) which is the point of intersection
Step-by-step explanation:
Use elimination to cancel out y by adding the equations:
5x=10
x=2
Plug x=2 into one of the equations and find y:
2(5)+2y=-2
10+2y=-2
2y=-12
y=-6
Therefore, x=2 and y=-6
Answer:
b² - 121
Step-by-step explanation:
(b +11)(b - 11)
b² - 11b + 11b - 121
b² - 121
