Answer:
Yes this is a function
Step-by-step explanation:
For every inout there is one output
Answer:
no because she would get the same total if she added it before or after
Step-by-step explanation:
Answer:
Part A: 7n + 30= -5 and 8n + 40= 16
Part B: 7(8) + 30= 86 and 8(8) + 40= 104
Part C: Company A saves you 12.
Step-by-step explanation:
Company A: 7n + 30
Company B: 8n + 40
7n + 30= -5 8n + 40= 16
7(8) +30= 86 8(8) +40= 104
7(2) + 30= 44 8(2) + 40= 56
56 - 44= 12
So ur going from a smaller shape to a larger shape....means the scale factor is more then 1. The scale factor is the number that u multiply the original shape by to get the other shape.
so lets look at DE...it is 2.....and D'E' is 6
so 2 * x = 6...with ur scale factor being x
2x = 6
x = 6/2
x = 3.....so the scale factor is 3....because multiplying the original shape by 3, gives u the other shape
Answer:
The cost of one pass is 25$
Step-by-step explanation:
Call the cost of one of the passes, P. So we have
63 = 13 + 2P - subtract 13 from both sides
50 = 2P - divide both sides by 2
25 = P
So the cost of one pass = $25
