Answer:
x = 3
y = 2
Step-by-step explanation:
Given
y = -2x + 8
y = x - 1
Substitute x - 1 for y in the first equation
We have
y = -2x + 8
x - 1 = -2x + 8
Add 1 to both sides to eliminate 1 on the left side
x - 1 + 1 = -2x + 8 + 1
x = -2x + 9
Add 2x to both sides to eliminate 2x on the right side
x + 2x = -2x + 2x + 9
3x = 9
Divide both sides by 3 to isolate x
3x/3 = 9/3
x = 3
Now substitute 3 for x in either equations to get y
Using the second equation, we have
y = x - 1
y = 3 - 1
y = 2
x = 3 and
y = 2

Answer: CAF = CBA = 85
Step-by-step explanation:
Using alternate segment theorem to solve the question.
The theorem states that an angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.
If CAE = 95 degree, then
CAF = 180 - 95 ( sum of angle on a straight line = 180 degree)
CAF = 85 degree
CAF = CBA = 85 degree because:
(An angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment)
