Answer: -418, 728, 446, -429, 1159, -696
Step-by-step explanation:
1. .
2. .
3. .
4. The sum of 429 and 429 is . We need to subtract this from 429, so
.
5. The sum of 510 and 319 is . Subtracting -330, we get
.
6. Call the unknown number "". Then
, so
. (Think about it.)
Answer:
A. y = 80x
B. g(x) = 80x
C. To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
Step-by-step explanation:
Part A:
To write an equation, use y= mx where m is the slope, x is the number of days, and y is the rent cost.
x and y remain the same in the equation.
To find m, use the slope formula with (5,465) and (7, 625).
It costs $80 a day.
The equation is y = 80x.
Part B:
Function notation replaces Y as g(x). So the equation is g(x) = 80x.
Part C:
To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
