Explanation
The sum of the three angles of a triangle has to be equal to 180 degrees.
So...
180-(75+50)
180-125
=55 degrees
X equals 55 degrees
Answer:
f(x), g(x), h(x)
Step-by-step explanation:
f(x) = x² + 6x - 1 = (x+3)² - 10 (-3 , 10) y=-3
g(x) = -x² + 2 = -(x-0)² + 2 (0 , 2) y=0
h(x) = 2x² - 4x + 3 = 2 (x-1)² + 1 (1 , 1) y=1
Answer is J because if 3 hours is $140 and 6 hours is $185 you calculate the difference. In this case $45 and divide it by 3, which is the difference between hours with those amounts, and answer is 15. And the only one with 15 is J.
