Answer:
x = -4, -2
Step-by-step explanation:
-x² - 6x - 8 = 0
x² + 6x + 8 = 0
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) = 0
(x + 4)(x + 2) = 0
x = -4, -2
$12552 because after rebate $3,138 would be reduced from the price making the ending price be $12,552
Answer: (2,-1).
Step-by-step explanation:
The given system of equations is
For , table of values is
x : 0 1 2
y : 2 0.5 -1
For , table of values is
x : -1 2 5
y : -2 -1 0
Plot these points on a coordinate plane and connect them be straight lines as shown below.
Form the graph it is clear that the lines intersect each other at (2,-1).
Therefore, the solution of given system of equations is (2,-1).
