Answer:
A.
Step-by-step explanation:
x2 - 3x - 10. = 0
x2 + 2x - 5x - 10 = 0
(x2 + 2x) (-5x - 10) = 0
x (x + 2) - 5 (x + 2) = 0
(x - 5) (x + 2) = 0
x - 5 = 0 x + 2 = 0
x = 5 or x = - 2.

Answer:
x=-10, y=-20
Step-by-step explanation:
Since both 2x and 3x+10 equals y, they equal each other.
2x = 3x + 10
x = -10
Substitute -10 for x
2(-10) = y
y=-20
Write the equation of the line passing through the two points. Show that this line is perpendicular to the given line.
(4,1) and (6,-5) y=1/3x-7
(1,-6) and (3,-10) y=1/2x-5
Please help, we learned this today and I’m really confused. How do you do it?
