Step-by-step explanation:
4x^2-6x-40
2(2x^2-3x-20)
=2(2x+5)(x-4)
The x-coord. of the vertex is halfway between the given zeros. Here, it'd be halfway between x=3 and x=9, which comes out to x = 6 (answer).
The answer is 1/20. 3/5 as a fraction is 12/20 and 13/20-12/20 is 1/20
A straight line equals 180 degrees.
The two equations when added together make a straight line so needs to equal 180:
10x-20 + 6x +8 = 180
Simplify:
16x - 12 = 180
Add 12 to each side:
16x = 192
Divide both sides by 16:
X = 192 / 16
X = 12
