Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4
X=82
it adds up to 180 so (x+6)+(x+10)=180
Answer:
Step-by-step explanation:
if CAB is a st. line and has arrows at end points then CAB is a straight line and also a straight angle (180°).
