To prepare for a party, Mark buys a small bunch of balloons for $4.00 and gift bags that cost $3.85 each. He spends a total of $61.75 on the balloons
and a gift bag for each person invited to the party. Write and solve an
equation to find x, the number of people Mark invited to the party.

Which function families have maximums and minimums? 1.)linear absolute value functions and exponential functions 2.) linear absolute value functions and quadratic functions 3.) linear absolute value functions and linear functions 4.) linear absolute value functions and constant functions

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 20 = x a. 5, 4 b. -5, -4 c. -5, 4 d. 5, -4

Acomposition of transformations maps δxyz to δx"y"z". the first transformation for this composition is , and the second transformation is a 90° rotation about point x'.
