1. Solve 2x + b = c for x.
2x + b - b= c - b subtract b from both sides
2x = c - b combine like terms/simplify
2x - 2= c - b - 2 subtract 2 from both sides to get x isolated
x = c - b - 2 simplify/final answer
The above process has an error. What is the mistake?
What is the correct final answer?
2. Given the function:
y = 3x2 − 10
What can replace y?
What is the range if the domain value is 3?
3.Given f(x) = −2x2 + 5, evaluate f(4)
4.Which of the following can be used to find the slope between two points?
What is the slope of the line that connects the points (3, 2) and (6, 10)?
5.The table below shows the number of jumping jacks completed after a given period of time in minutes.
Time (minutes) Jumping Jacks
1 50
2 100
3 150
4 200
Considering the jumping jacks: 50, 100, 150, 200, what is the common difference?
Now, think of this table as a set of ordered pairs. This means that the first row can be placed in an ordered pair as (1, 50). The second row can be written as (2, 100). Using this, what is the slope of the line that connects the first two points?
What is the slope of the line that connects the 3rd and 4th point?
What is the slope of the line that connects the 1st and the 4th point?
Is the common difference (aka slope aka rate of change) constant?
Why is it or is it not constant?
