Hope this helps!
6x² + 12x = 0
6x(x + 2) = 0
1. 6x = 0
⇒ x = 0
2. x+2 = 0
⇒ x = -2
Solutions are: {0, -2}
Answer:
B. (1,-8)
Step-by-step explanation:
Slope of the first one:
(-6-0)/(0--3) = -6/3 = -2
y = -2x - 6
3y + 30 = 6x
y + 10 = 2x
-2x - 6 + 10 = 2x
4 = 4x
x = 1
y = -2(1) - 6
y = -8
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc ⇒ x = 40/2 = 20°
