Please equate 2x^2 -8x -90 to zero: <span>2x^2 -8x -90=0
Next, reduce </span>2x^2 -8x -90=0 by div. all terms by 2: x^2 -4x -45=0
Next, factor the poly: (x-9)(x+5) = 0
Set each factor = to 0 and solve for x:
x-9=0 => x=9
x+5=0 => x= -5

Answer:
<em>m</em> = -2
General Formulas and Concepts:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step-by-step explanation:
<u>Step 1: Define function</u>
y = -2x + 5
<u>Step 2: Break function</u>
Slope <em>m</em> = -2
y-intercept (0, 5)
Multiply by 100, as per cent means per 100.
X-5) = 2(x-1)
3x-15 = 2x - 2
x - 15 = -2
x = 13
