Answer:
Part a) 
Part b) 
Step-by-step explanation:
Part a) Write an equation for T (d)
Let
d ----> the number of days
T ---> the time in minutes of the treadmill
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope or unit rate is

The y-intercept or initial value is

substitute

Part b) Find T (6), the minutes he will spend on the treadmill on day 6
For d=6
substitute in the equation and solve for T


Answer:
16
Step-by-step explanation:
21.60 divided by 1.35=16
Answer:
2 1/4 cups of sugar
Step-by-step explanation:
You could change 3/4 to a decimal which is .75
Then multiply that by 3
The result was 2.25, so you would convert that into a fraction which would be 2 1/4
Answer:
1467
Step-by-step explanation:
i know this because taking a negative number and a positive is like adding and then you subtract 144 and you get 1467
Answer:


Step-by-step explanation:
Given

Solving (a): An equivalent inequality
We have:

Multiply both sides by -1 (this changes the inequality)


Solving (b): Values of u from least to greatest
implies that u ends at -4, starting from negative infinity
So, the list is:
