Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.
Step-by-step explanation:
Slope intercept form standard formula:
y = mx + c
where,
y= y intercept
x= x intercept
m = slope
c = constant
We are given:
y = - 1.3(x + 3)2 - 9
y = - 2.6x + 7.8 - 9
y = -2.6x -1.2
So,
Slope = m = -2.6
constant = 1.2

Answer:
x^2 + x - 72 = 0
Step-by-step explanation:
x(x + 1) = 72 should be re-written in the standard form of a quadratic:
x^2 + x - 72 = 0. Same as the first answer choice.
