Answer:
B and D
Step-by-step explanation:
Write as a quadratic
-2x² - 3x + 5 = 0
Factor
-2x² - 5x + 2x + 5 = 0
-x(2x + 5) + 1(2x + 5) = 0
(1 - x)(2x + 5) = 0
To make the equation 0, x is either 1 or -5/2.
Your vertex would be (-1,-5)
and your axis of symmetry is x=-1
Step-by-step explanation:
115 = 5x + 15
115 - 15 = 5x
100 = 5x
20 = x
