Answer:
-4m-17
Step-by-step explanation:
g(2m+7) = -2*(2m+7) -3
= -4m -14 -3
= -4m -17
For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:
b = 25

Perhaps you can tell that the general formula is
.. (measured value - actual value)/(actual value) * 100% = % error
Answer:
3/4
Step-by-step explanation:
The slope of the line is
m = (y2-y1)/(x2-x1)
= (-2--5)/(6-2)
= (-2+5)/(6-2)
=3/4
