Number 7 is C because all of them are less than 1/2 or 0.50
Answer:
(0,-5) and (-4,3)
Step-by-step explanation:
The given equations are

Make y the subject in the second equation;

Substitute into the first equation;

Expand:





When x=0,

This gives; (0,-5)
When x=-4

This gives (-4,3)
Answer:
x = 12, y =
Step-by-step explanation:
a || b
5x - 7 = 3x + 17 Alternative Interior Angles
x = 12 Algebra
Angle 3x + 17 = 53 Substitution
53 + 4y + 3 = 180 Supplementary Angles
y = 31
Angle 4 would be 77degrees because angle two is vertical to angle four.
Angle 3 and Angle 1 are equal because they are vertical to each other.
You would subtract 180 (degrees) minus 77 (degrees) and get 103 (degrees).
So Angle 3 and Angle 1 would both be 103 degrees.
You would get 180 degrees from the line.
