Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
Find the x-intercepts by setting the function equal to 0
0 = 2x^2 - 3x - 2
Factor
2x^2 - 4x + x - 2 = 0
2x(x - 2) + 1(x - 2) = 0
(x - 2)(2x + 1) = 0
x - 2 = 0
x = 2
2x + 1 = 0
2x = -1
x = -1/2
the x-intercepts are at x = -1/2 & 2
9/12 = (9/3) / (12/3)= 3/4.
