(5,9)
Step-by-step explanation:
f(x)=x+2
f(3)=3+2
=5
g(x)=5x-1
g(2)=5.2-1
=10-1
=9
Answer:
90+60=150
180-150=30
x=30
180 is the sum for an triangle and half a circle but since it give no other explanation i'm assuming its for a right triangle

Answer:
CPQ = 135
JCY = 25
Step-by-step explanation:
The two angles form a straight line, so the sum of the angles is 180
8x-7 + 12x+57 = 180
Combine like terms
20x +50 = 180
Subtract 50 from each side
20x+50-50 = 180-50
20x = 130
Divide each side by 20
20x/20 = 130/20
x =6.5
We want to find CPQ
CPQ = 12x+57
=12(6.5) +57
=78+57
135
These angles are vertical angles and vertical angles are equal
4x+5 = 2x+15
Subtract 2x from each side
4x-2x+5 = 2x-2x+15
2x+5 = 15
Subtract 5 from each side
2x+5-5 =15-5
2x = 10
Divide each side by 2
2x/2 = 10/2
x =5
We want to find JCY
JCY = 4x+5
= 4(5)+5
=25
