Answer:
11. (x-2)/(x+8)
12. 9+t
13. h = 2A/b
Step-by-step explanation:
11. Since x is used to represent the number, 2 less than a number is x-2. 8 more than a number is x+8. The quotient of the first and second of these is the first one divided by the second one:
... (x -2)/(x +8) . . . . . parentheses are required unless the expression is typeset:
12. Apparently, we're to assume the salesman keeps on driving. If he had any sense (or a good union), he would stop after 9 hours. t hours added to 9 is ...
... 9 + t
13. Divide by the coefficient of h.
... h = A/((1/2)b) = 2A/b

Answer:
Part A: 1
Part B: -4
Step-by-step explanation:
In a coordinate , the x-coordinate represents the input of a function and the y-coordinate represents the output.
Part A:
We're looking for the point the line passes through with an x-coordinate (input) of -3. This point is (-3,1) and therefore the output is 1 when the input is -3.
Part B:
We're looking for the point the line passes through with a y-coordinate (output) of 2. This point is (-4,2) and therefore an input of -4 yields an output of 2.
