The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).
The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].
The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].
Overall, this function has a domain of
[-4, 1) U [-1, 2] U (2, 5]
(where U means "union" in the set-theoretic notion)
But this also simplifies to the interval [-4, 5].
These correspond to the <u>first</u> and <u>last</u> choices.
Answer:
(3,1) --> One solution
Step-by-step explanation:
Start by multiplying the first equation by 4:
-7x(4)+2y(4)=-19(4)
-28x+8y=-76
In this scenario, we can eliminate 8y by subtracting the two equations:
-34x=-102
Divide both sides by -34
x=3
Plug 3 back in for x to solve for y
-7(3)+2y=-19
-21+2y=-19
Add 21 to both sides
2y=2
Divide both sides by 2
y=1
(x,y)=(3,1)
Ok line y because you have to plot two right
