Answer:
(-1, 6)
Step-by-step explanation:
{-c + 2d = 13
{-9c - 4d = -15
-⅑[-9c - 4d = -15]
{-c + 2d = 13
{c + 4⁄9d = 1⅔ >> New equation
______________
2 4⁄9d = 14⅔
______ _____
2 4⁄9 2 4⁄9
d = 6 [Plug this back into both equations to get the c-value of -1]; -1 = c

Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
