Answer:
the missing exponent is 2
Step-by-step explanation:
First you must distribute the 2x to the numbers inside the parentheses
(2x * x) + (2x * -1) = 3
- 2x = 3
To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides
- 2x - 3 = 0
Use the quadratic equation to solve this (image of the quadratic equation is below)
Remember that quadratic functions are set up like so:

That means that in this equation...
a = 2
b = -2
c = -3
^^^Plug these numbers into the quadratic equation and solve...





Keep in mind that +/- is ±

What im thinking is this: F(a) = f(b) so have 2 equations written and plug a into one and b in the other
(a-2)^3+8 = a^3-8+8 = a^3
= a^3 = b^3 square root both side = a=b
<span>(b-2)^3+8 = b^3-8+8 = b^3
Thus it is 1:1.</span>

Answer:
y = -3/4x -5
Step-by-step explanation:
(4, -8) and (-8, 1)
m = (y2-y1)/(x2-x1)
m= (1+8)/(-8-4)
m = (9)/(-12)
m = -3/4
y - y1 = m(x-x1)
y + 8 = -3/4(x -4)
y + 8 = -3/4x + 3
y = -3/4x -5
