Answer:
115
Step-by-step explanation:
If two angles are supplementary, it means that their measures add up to 180 degrees.
So to find the measure of the other angle you would do:
180-65=115
So the other angle measures 115 degrees.

The answer is C 12.5 -0.031
Answer:
B
Step-by-step explanation:
The maximum value of the function is the y- coordinate of the vertex.
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = - 3x² - 15x + 9 ← is in standard form
with a = - 3 and b = - 15, thus
= - 
= - 2.5
Substitute x = - 2.5 into the equation for y- coordinate of vertex
y = - 3(- 2.5)² - 15(- 2.5) + 9 = - 18.75 + 37.5 + 9 = 27.75 → B
Answer:
x = -42 is your answer
Step-by-step explanation:
x/6 = -7
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Multiply 6 to both sides
(x/6)(6) = (-7)(6)
x = (-7)(6)
Simplify. Multiply 6 with -7
x = (-7)(6)
x = -42
