Answer: x = 56
It’s a supplementary angle
Step-by-step explanation:
It’s a supplementary angle if their measures add to 180 degrees
is the equation
2x + 68 = 180 degrees
2x = 180 -68
2x = 112
x = 112/2
x = 56
The answer to your question is answer choice D
Answer:
y = 3(x+1)^2 - 4
Step-by-step explanation:The general form of the equation of a quadratic function whose vertex is (h,k) and whose leading coefficient is a is:
y - k = a(x-h)^2, or
y = a(x-h)^2 - k
Substituting the coefficients of the vertex (-1, -4), we get:
y = a(x + 1)^2 - 4
Substituting the coordinates of the given point, (1,8), we get:
8 = a(1+1)^2 - 4, which simplifies to:
8 = a(2)^2 - 4, or
8 = 4a - 4. Then 4a = 12, and a = 3.
Thus, the desired equation is y = 3(x+1)^2 - 4 (answer j).
