<span>1/2-(5/4) = x+1/4 // - x+1/4
1/2-x-(5/4)-(1/4) = 0
1/2-x-5/4-1/4 = 0
-x-1 = 0 // + 1
-x = 1 // * -1
x = -1
x = -1

80 degrees since the corrisponding angle, A, is also 80 degrees
Answer:
2
Step-by-step explanation:
2(3x²-5)-5=9
6x²-10-5=9
6x²-15=9
6x²=9+15
6x²=24
x²=24/6
x²=4
x=2
Step-by-step explanation:
First, find the zeroes of the parabola







So the zeroes or where the curve crosses the x axis is at 4 and -3.
Now, we take the derivative of the function.

Plug in -3, and 4 into the derivative function


So at x=-3, our slope of the tangent line is -7 and must pass through (-3,0). So we use point slope formula.



At x=4, our slope of tangent line is 7, and pass through (4,0) so


So the equations of tangent is
