Answer:
- a) 3
- b) 6
- c) 9
- d) the outputs are 3 times as far apart as the inputs
Step-by-step explanation:
(a) "x" in considered to be the input to the function f(x). The variable(s) in parentheses as part of the function name are the inputs. The function value itself is the output.
That is, for an input (x-value) of 0, the output (f(0)) is 5. For an input of 1, the output (f(1)) is 8. These input values (0 and 1) are 1 unit apart: 1 - 0 = 1. The corresponding output values are 3 units apart: 8 - 5 = 3.
(b) Inputs -1 and 1 are 2 units apart (1-(-1)=2). The corresponding output values, 2 and 8, are 6 units apart. (8-2=6)
(c) Inputs 0 and 3 are 3 units apart. The corresponding output values, 5 and 14, are 9 units apart.
(d) The ratio of output differences to input differences can be seen to be ...
... 3/1 = 6/2 = 9/3 = 3
Output differences are 3 times input differences.

<em>Comment on the problem</em>
These ratios are constant everywhere, so the function is considered to be "linear." The ratio is the "slope" of the line you see when the function is graphed.
Answer:
B
Step-by-step explanation:
x = 4 and y = 9 and z = 7
x(y + z - 32) = 4 · (9 + 7 - 32) =
= 4 · (16 - 32) = 4 · (-16) = <u>-</u><u>6</u><u>4</u>
The compound inequality that shows the range of number is:
<u><em>Explanation</em></u>
Isabella is thinking of a number .
Given that, 6 less than 6 times her number is between 24 and 48.
So, 6 less than 6 times the number means:
So, the inequality will be....
<em>That means, the number that Isabella might be thinking of will be in between 5 and 9. </em>
So, the compound inequality that shows the range of number is:
350 plus 10?
that equal or do tey want something more extreme
