Step-by-step explanation:
Answer:
C. 0, -1, 3
Step-by-step explanation:
Note: There is no graph. I assume you mean "zeroes/roots" by "solutions".
x(x^2-2x-3)=0
/(x^2-2x-3)
x=0
x^2-2x-3 = x^2+x-3x-3 = x(x+1) + ( -3(x+1) = (x-3)(x+1)
/(x-3) --> x +1 =0, x=-1
/(x+1) --> x-3 = 0, x=3
7x+2y=-17
steps:
x=2x + 5x
y=3y - y
sum=-5 -12
So with these equations we need to find the y-intercept and the slope because:
y = mx+b
y = f(×)
b = y-intercept
m = slope (slope = rise/run, rise over run)
rise is y-axis
run is x-axis
The y-intercept is (0,-2)
So now we know that one of the answers must have -2 in it
b = -2
m= rise/run = -2/3
The answer is:
Do 142degrees subtract that by 180 that is the angle on the other side then put that answer plus 49 equal to 180 then there is your answer
