3x^2 + 11x - 4 = 0
Look for two factors of -12 that add up to 11 -> -1 and 12
(3x - 1)(x + 4) = 0
x = 1/3 or -4
So the answer you want is D
An easy way to answer questions like this is simply to try each option until one works.
3 x 0^2 + 11 x 0 = 0 so not A
3 x (-11/3)^2 + 11 x -11/3 = 0 so not B
3 x 4^2 + 11 x 4 = 92 so not C
3 x (1/3)^2 + 1 x 1/3 = 12/3 = 4 correct
I doubt E would be marked correct but in fact A and E are opposite statements so one of them must be true
I don’t even know , no cap
First graph your x and y intercept then pick any two points on the line.
that's the equation used to find your slope
Example:
(4,2) (8,6) let's say those are the points you pick from the line
so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)
then subtracts 8-4=4 (8is your x2 and 4 is your x1)
then your left with
if you can reduce the reduce in this case you can which leaves you with
and that's how you find the slope
Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and co secant functions<span>.</span>
