Answer:
(-4,-10)
Step-by-step explanation:
Given :
To Find :What is the solution to the system of equations?
Solution:
y=x-6 ---(1)
x= -4 ---(2)
Now we will use substitution method
Now put value of x from equation 2 in equation 1
⇒y = -4-6
⇒y = -10
Thus (x,y)=(-4,-10)
Hence the solution to the system of equations is (-4,-10)

Answer:
- y-intercept: (0, -6)
- x-intercepts: (-3, 0), (-1, 0), (1, 0)
Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
