Answer:
- c(m) = 39.95 +0.35m
- 85 minutes over 500
Step-by-step explanation:
Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...
c(m) = 39.95 +0.35m
__
For a cost of 69.70, the number of excess minutes can be found by solving ...
69.70 = 39.95 +0.35m
29.75 = 0.35m . . . . . . . . . subtract 39.95
29.75/0.35 = m = 85 . . . . divide by the coefficient of m
The number of minutes of usage over 500 is 85.

Answer: Table 2 and table 3 are the functions which have an additive rate of change of 3.
Step-by-step explanation:
Step-by-step explanation:
The rate of change of a linear function is given by:-
For table 1,
.....> which is not positive.
For table 2,
.....> which is positive.
For table 3,
.....> which is positive.
Hence, Table 2 and table 3 are the functions which have an additive rate of change of 3.

Answer:
680 oranges
15 levels
Step-by-step explanation:
Add 2, add 3, add 4, add 5.....
1+3+6+10+15+21+28+36+45+55+66+78+91+105+120=680
15 levels
He can’t add a 16th level, because it would have 136 oranges, which would put him over 800.
According to the definition of a function, since every element in the domain should be mapped to a single element in the codomain, the output of -2 should be either 2 or -1 but not both.
Note that the other elements in the domain have unique images.
So, to make the mapping a function, we need to remove (-2, 2) or (-2, -1).
Of these, (-2, -1) is only given in the options.
Hence, the ordered pair to be removed is (-2, -1).
6(x + 2) = 3(2x + 4)
STEP ONE:
Multiply both sides
6x + 12 = 6x + 12
STEP TWO:
You can see both sides are identical, therefore you can conclude there are infinite solutions
