Good morning Sir/Ma'am!
Answer:
f(r) = 40r + 26
If she can only afford 10 rolls, then the maximum number of nickels Cindy will have is:
f(10) = 40(10) + 26 = 426 nickels
Step-by-step explanation:
Given function f(r)=40r+26, where r is the number of rolls of nickels she gets.
as it is already mentioned that she can get up to 10 rolls of nickels.
Therefore domain of function contains r ≤10,such that r is a natural number.
i.e.Domain of f(r)=all integers from 1 to 10, inclusive.
Domain of a f(x) is a set of values of x which make function f(x) well defined.

Rise over run is 7 over 2 so 7/2 is the slope
The first one is D
The second one is true
Answer:
The answer is True.
Step-by-step explanation:
-3x - 10 > -31
-3(5) - 10 > -31
-15 - 10 > -31
-25 > -31
True.
Answer:
y=-6x-14
Step-by-step explanation:
1. y=mx+b
2. y=-6x+b
3. plug in the point to y and x
4. -8=-6(-1)+b
5. -8= 6+b
6. -8-6=b
7. -14=b
8. Equation = y=-6x-14
