Theorem
In a triangle, the measure of an exterior angle equals the sum of the measures of its two remote interior angles.
x + y = z
4n - 18 + n + 8 = 133 - 6n
5n - 10 = 133 - 6n
11n = 143
n = 13
z = 133 - 6n = 133 - 6(13) = 133 - 78 = 55
Answer: C. 55
-4x > 16
Divide -4 on both sides. Don't forget to flip sign since we are dividing by a negative number.
x < -4
Answer:
y = -x^2 − 2.5x + 350
Step-by-step explanation:
y = (10 + 0.5x)(35 − 2x)
y = 350 − 20x + 17.5x − x^2
y = 350 − 2.5x − x^2
