X / 40 = 4 /32 ( similar triangles)
x / 40 = 1 / 8
x = 40/8 = 5 answer
Quadratic equation: ax² + bx + c =0
x' = [-b+√(b²-4ac)]/2a and x" = [-b-√(b²-4ac)]/2a
6 = x² – 10x ; x² - 10x -6 =0
(a=1, b= - 10 and c = - 6
x' = [10+√(10²+4(1)(-6)]/2(1) and x" = [10-√(10²+4(1)(-6)]/2(1)
x' =5+√31 and x' = 5-√31
Answer:
y = -1 (x - 1)² + 4
Step-by-step explanation:
im pretty sure thats right but if not sorry :(
The correct answer is the second choice, -52
