Answer:
y = 148°
Step-by-step explanation:
4x - 18 = 2x + 12 (alternate exterior angles are congruent)
Collect like terms
4x - 18 = 2x + 12
4x - 2x = 18 + 12
2x = 20
Divide both sides by 2
x = 10
y = 180 - (2x + 12) (linear pair theorem)
Plug in the value of x
y = 180 - (2(10) + 12)
y = 180 - (20 + 12)
y = 148°
You would divide 100/20 and get 5. then u would multiply 9 times 5 equals 45 then add a decimal to get ur answer 0.45
Answer:
Step-by-step explanation:
y = -3(x-3)^2 + 4
Here you go -12.4 - 5.75 x is your Answer
