Answer:
0.2
Step-by-step explanation:
4.5 + 3.2 = 7.7
7.7 - 7.5 = 0.2
Input 15 as the initial value and (3, 90) as x and y to get the equation 90=m(3)+15. Isolate m to get m=25. Each shirt costs $25 and the equation that represents the scenario is y=25x+15.
The answer is 3x-12y because you combine the like terms so 2x+x=3x and -8y-4y=-12y
Answer:
Domain:
[-5,-2) U (-2,3.5) U (3.5,5]
Range:
[-3 0) U (0,5]
It is not a function because x = 1 has two different outputs (3 & 5)
