Step-by-step explanation:
5x+2y=-11
2x+2y=5
so you find values that match or can multiply by something to match-2
5x+2y=-11
- 2x+2y=5
=3x+0y=-16
3x/3=-16/3
x=5 1/3
then substitute x in one of the equations to get y
Answer:
x = - 8, x = 2
Step-by-step explanation:
Given
f(x) = x² + 6x - 16
To find the x- intercepts equate f(x) to zero, that is
x² + 6x - 16 = 0 ← in standard form
(x + 8)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 2 = 0 ⇒ x = 2
There is no solution to this system of equations because they both have the same slope.
If two lines have the same slope, but are not identically the same line, then they will never intersect. There is no pair (x, y) that could satisfy both equations, because there is no point (x, y) that is simultaneously on both lines. Therefore, these equations are said to be inconsistent, and there is no solution.
