Answer:
z=16
Step-by-step explanation:
We know for sure that since A and B are parallel that 1, 4, 5, and 8 are equal.
So then the equation is simply 123=7z+11---> 7z=112----> z=16
Answer:
y = -2x+6
y=8 when x = -1
Step-by-step explanation:
2x + y = 6
Slope intercept form is y = mx+b where m is the slope and y is the intercept
Solve for y
Subtract 2x from each side
y = -2x+6
The slope is -2 and the y intercept is -6
Let x = -1
y = -2(-1) +6
y = 2+6
y=8
(-1,8)
