Mrs. Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale. Math Game: M(d)=x²-9x-10
Reading Game: R(d)=2x+10

(a) Solve the system algebraically. After how many days is the revenue for each game the same?

(b) Graph this system to show the solutions. Label each axis appropriately (I mainly need help on this part of the question)

Mrs. Galicia dropped a ball from the top of a tower. At the same time, her son, Antonio, launches a rocket from a different level of the tower.

The height of the tennis ball in feet after t seconds can be represented by the quadratic function:

b(t)= -t² - 2t + 36

The height of Antonio's rocket after t seconds can be represented by the linear function: p(t) = -2t + 20

(a) What are the two solutions to this system? Show your work.

(b) Explain which solution is not reasonable in this situation.

(c) After how many seconds do the rocket and the ball reach the same height

Ivan began dividing g2  – 6 by g + 1, noting that . he started by placing g in the quotient, as shown below. what is g2  – 6 divided by g + 1? g –  1 –  g + 1  – g  –  7 + g  –  5  + 

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
