Doug has 8 square pieces of wood. Each piece of wood has a side length of c centimeters. The total area of all 8 pieces of wood is 200 square centimeters. Create a quadratic equation Doug can use to find the side length of each piece of wood.

A band sells x premium tickets and y regular tickets for a concert.

A premium ticket costs $20.

A regular ticket costs $5 less than a premium ticket.

The band raises $2145 from selling tickets.

Select the coefficients to complete the equation representing the relationship between x and y.

​ ​ (a)   x + ​ (b)   y = 2145

A function is shown. Select all the effects on the graph of the function when is multiplied by 3.

The equation for the function f is shown.

$$f\left(x\right)-\frac{1}{2}x+3$$

The quadratic function g has the following properties:

g has a lesser y-intercept than f

The maximum value and y-intercept of g are not equal.

First g increases, and then it decreases.

Drag the vertex and y-intercept labels to show possible locations for the vertex and y-intercept of g.

Graph the solution to the system. The first equation has been plotted for you.

y = -3x-3

y= 4x +4

What is the value of y in the solution to this system of equations?

Which linear equation best models the scatter plot?

A carnival performer claims to be able to guess a person's weight within 4lbs of their actual weight or the person wins a prize. If a person weighs 142lbs, which equation can be used to find the minimum and maximum weights the performer can guess without the person winning a prize?
