I thin kthe answer your looking for is Vertical angles. Hope i helped! Brainliest?
and i know its ccorect becuase because the interior angles of vertical angles are congruent.
Answer:
I think it is a) exponential
Answer:
x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Step-by-step explanation:
Solve for x:
y = -x^2 - 4 x + 7
y = -x^2 - 4 x + 7 is equivalent to -x^2 - 4 x + 7 = y:
-x^2 - 4 x + 7 = y
Multiply both sides by -1:
x^2 + 4 x - 7 = -y
Add 7 to both sides:
x^2 + 4 x = 7 - y
Add 4 to both sides:
x^2 + 4 x + 4 = 11 - y
Write the left hand side as a square:
(x + 2)^2 = 11 - y
Take the square root of both sides:
x + 2 = sqrt(11 - y) or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
x = sqrt(11 - y) - 2 or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
Answer: x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Answer:
2. (1.5, 1.5)
Step-by-step explanation:
midpoint = (x1+x2)/2 , (y1+y2)/2
A = (-3,-3) and B = (6,6)
midpoint = (-3+6)/2, (-3+6)/2
= 3/2 , 3/2
