Consider the following pair of equations:

y = 3x + 3
y = x − 1

explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

What is the volume of the sphere shown below with a radius of 3?

What is 1/2 x (6 x 4)+3 + 2 show your work

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
