Answer:
x=2 and y=-6 aka. (2,-6) which is the point of intersection
Step-by-step explanation:
Use elimination to cancel out y by adding the equations:
5x=10
x=2
Plug x=2 into one of the equations and find y:
2(5)+2y=-2
10+2y=-2
2y=-12
y=-6
Therefore, x=2 and y=-6
Function: y = 4|x| - 1.
Domain: R (all real numbers).
Range: As we know, the absolute value of x is always a non-negative number:
|x| >= 0
4|x| >= 4 * 0
4|x| >= 0
4|x| - 1 >= -1
y >= -1 <----- this is the range
I hope this helps. =)
