Answer:
Range is between -7 and 8
-7<y<8
Step-by-step explanation:
Range means series of number between lowest and highest output(y-axis) of a function.
Notice on the graph, the lowest y you can get is -7 and highest is 8. Other numbers are in between.
Thus, the range is in between of -7 and 8.
It would be: -12 + 15x = 3(-4+5x)
So, after common factor out, your answer is 3(-4+5x)
Hope this helps!
20x+5y=120
10x+7.5y=80 multiply this one by 2
___________
20x+5y=120
20x+15y=160 subtract
___________
-10y=-40 divide both sides by -10
____________
y=4
20x+5(4)=120 plug 4 in for y in the first equation
20x+20=120 multiply
20x=100 subtract
x=5 divide to find x
