Answer:
x=-3
Step-by-step explanation:
If x=-3, then
x³+x²-2x+12=-27+9+6+12=-27+27=0
If this is true, then x+3 is a factor. So:
x³+x²-2x+12/x+3=x²-2x+4
So the factors of x³+x²-2x+12 are:
(x+3)(x²-2x+4)
((x²-2x+4) has no real roots)........
Answer:
Let x represents the hours and y represents the total fees(in dollars)
As per the statement:
(a)
For a house call, a veterinarian charges $70, plus $40 an hour
"$40 an hour" means 40x
then;
the equation we get;
.....[1]
(b).
Find the x-intercept.
x-intercept states that the graph cross the x-axis.
Substitute y = 0 in the equation and solve for x;
we get;

y-intercept states that the graph crosses the y-axis i.e
Substitute x= 0 in the equation and solve for y;

Therefore, x-intercept and y-intercept of equation [1] are:
and 70
