Hi Brainiac
1/2(2x-6) = -6
We need to distribute
(1/2)(2x) + (1/2)(-6) = -6
2x/2 + -6/2 = -6
x - 3 = -6
x = -6 + 3
x = -3
Thus, The answer is D
I apologize for the late answer :(
I think the correct answer would be a pyramid. This is the shape where the vertex is an apex as well. The apex is the highest of a shape and the vertex is the is the point where edges meet which would be the same for a pyramid. Hope this helped.
Answer:
x =
Step-by-step explanation:
Square both sides.
y² = (2x + 1) / (x - 1)
Multiply both sides by (x - 1).
y²(x - 1) = 2x + 1
xy² - y² = 2x + 1
xy² = 2x + 1 + y²
xy² - 2x = 1 + y²
x(y² - 2) = 1 + y²
x =
