Find the height of a triangle that has an area of 30 square units and a base measuring 12 units.
How many solutions exist for the given equation?

Timmy writes the equation f(x) =1/4 x - 1. He then doubles both of the terms on the right side to create the equation g(x) =1/2 x - 2. How does the graph of g(x) compare to the graph of f(x)?
The line of g(x) is steeper and has a lower y-intercept.
2x + 3y = 2 y =1/2 x + 3
When the equation is solved for a, such that b is the numerator of the resulting fraction, what is the denominator of the fraction?

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb weights and y represents the number of 10 lb weights, which equation can be used to find the number of each type of weight Bob has?
3x = 50 - 10y
How does the slope of g(x) compare to the slope of f(x)?
The slope of g(x) is less than the slope of f(x).
Which interval contains a local minimum for the graphed function?
Which linear function represents the line given by the point-slope equation y - 8 =1/2 (x - 4)?

The amount of potential energy, P, an object has is equal to the product of its mass, m, its height off the ground, h, and the gravitational constant, g. This can be modeled by the equation P = mgh.
What is f(0)?
Which equation can be used to find q, the number of quarters Alex has?
0.05(84 - q) + 0.25q = 17.80
y = -2/5x + 1 y = 3x - 2
