Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
5x + 2y = 21 ⇒ 5x + 2y = 21
-1x - 1y = -9 ⇒ <u>5x + 5y = 45</u>
<u>-3y</u> = <u>-24</u>
-3 -3
y = 8
5x + 2(8) = 21
5x + 16 = 21
<u> - 16 - 16</u>
<u>5x</u> = <u>5</u>
5 5
x = 1
(x, y) = (1, 8)
Answer:
Step-by-step explanation:
We can draw a perpendicular line through the two parallel lines to create a pentagon (there is an image attached in case you need to see where the line intersects the two parallel lines). Since the angle sum of a pentagon is 
, we can solve for 
.
(Angle sum of pentagon is )
(collect like-terms)
Hope this helps :)
