Linear Equations
John is saving up to buy a new video game console that costs $300. He already has $100 saved, and he plans to save $20 per week. Write an equation that represents John's savings, where x is the number of weeks he has been saving and y is his total savings.
y = 20x + 100

A line passes through the points (4, 3) and (-2, -1) .Determine the x-intercept of the line.
x = -1/2
Sqrt (X) goes through the following transformations.
It is horizontally stretched by a factor of 2.
It is shifted 3 units to the left.
It is shifted 4 units down.
Sqrt (x-3)/2 - 4
Solve
4x + 3y = 17
2x - y = 1
x=2, y=3
g(x) =1/x is

g(x) = -2/(x-3) - 5
A chemist is mixing two acid solutions. Solution A is 30% acid, and Solution B is 50% acid. The chemist needs 10 liters of a 40% acid solution.
x is the amount (in liters) of Solution A used.
y is the amount (in liters) of Solution B used.
How much of each solution the chemist should mix.
5 liters each.
You are given the graph of a function g(x) , which passes through the points (1,2), (3,5), and (6,7).
List a point that must be on the graph of g-1(x).
(2,1), (5,3), or (7,6)
