Answer:
Step-by-step explanation:
Answer:
<em>B. a = y - k/(x-h)² </em>
Step-by-step explanation:
Given the expression y = a (x-h)² + k
First make a the subject of the formula
Subtract k from both sides
y = a (x-h)² + k
y- k = a (x-h)² + k - k
y - k = a (x-h)²
Divide through by (x-h)²
y - k/(x-h)² = a
a = y - k/(x-h)²
Hence option B is correct
Where's the rest of the question?
All angles in a triangle = 180. SO we can make an equation to find y:
79+37+y=180
116+y=180 (combine like terms)
y=64 (subtract the 116)
