#1 Mrs. Galicia sells online math and reading games. Her 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)=x^2-9x-10
Reading game: R(d)=2x+10
Solve the system algebraically.
a) what are the two solutions to this system? SHOW YOUR WORK.
b) after how many days is the revenue for each game the same?
#2 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)=-t^2-2t+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?
Answers
M(d) = x^2 - 9x - 10
R(d) = 2x + 10
A. Since M(d) and R(d) are technically the same term, we can substitute them for the other.
Substitute M(d) for R(d)’s expression
2x + 10 = x^2 - 9x - 10
x^2 - 11x - 20 = 0
Use this equation to put in the quadratic formula
x = (-(-11) +/- √((-11)^2 - 4(1)(-20)))/2(1)
x = (11 +/- √201)/2 or x = 12.5887… and -1.5887…
B. 12.6 days as there can’t be negative days
2.
Do the same substitution as the previous question
-t^2 - 2t + 36 = -2t + 20
Get all parts on the same side
t^2 - 16 = 0
Optional: quadratic formula
t = (-(0) +/- √((0)^2 - 4(1)(-16)))/2(1)
t = 4 and -4
b. -4 is not reasonable in this situation as time cannot be negative
c. 4 seconds

determine the zeros of the function f(x) = 2(x – 6)^2 – 4
Answers
Answer:
x = 6 ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the zeros equate f(x) to zero , that is
2(x - 6)² - 4 = 0 ( add 4 to both sides )
2(x - 6)² = 4 ( divide both sides by 2 )
(x - 6)² = 2 ( take square root of both sides )
x - 6 = ± [tex]\sqrt{2}[/tex] ( add 6 to both sides )
x = 6 ± [tex]\sqrt{2}[/tex]
The zeros are x = 6 - [tex]\sqrt{2}[/tex] , x = 6 + [tex]\sqrt{2}[/tex]

1. The amount of Kelly's paycheck varies directly with the number of hours
she works. Kelly receives $139.80 for 12 hours of work.
(a) Write a direct variation equation that relates the amount of Kelly's paycheck, y, to the number of hours, x,
that Kelly works.
(b) use the equation to find the amount of Kelly’s paycheck when she works 40 hours.
Answers
Answer:
(A) p=11.65h
(B) h=22
(C) p=466
Step-by-step explanation:
A) The equation for direct variation is usually y=kx, K being the constant variation, Y being the amount of Kelly’s paycheck, and x being the number of hours. So the equation would turn into p=kh. Then you have to plug in the numbers they gave you which would be, 139.80=12k. When you plug that into a calculator you get, K=11.65. So, the answer would be p=11.65h
B) For B we’re keeping the same format of the equation from question A which would be p=11.65h, but were plugging in p, the amount of paycheck she receives so, the 256.3 so our new equation would be 256.3=11.65h, putting that into a calculator will give you the answer which is h=22.
C) Same thing as question B we are keeping the same format of the equation as Question A but this time we’re pluggin in h, the amount of hours Kelly works. So our equation would be p=11.65(40). Plugging that into the calculator will give you p=466.
Hope this helps.

Valentina's parents are planning a trip to the Typhoon Towers resort. They plan to get a 6-day Fun Pass, which will give Valentina access to all the slides and pools at the resort during their stay. Her parents also plan to get her a $30 arcade pass. Altogether, Valentina's parents will spend $129 on passes. What is the daily cost of a Fun Pass?
Answers
Answer:
$16.50
Step-by-step explanation:
Subtract the money $129-$30=$99
$99 divided by 6
The daily cost of the fun pass paid by Valentina's parents is $16.5 per day.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the total cost for x number of days.
Since they plan to get her a $30 arcade pass, hence b = 30. Also they will spend $129 on passes. y = 129, x = 60. Hence:
129 = m(6) + 30
6m = 99
m = 16.5
Therefore the daily cost of the fun pass is $16.5 per day.

Hey so I’m not quite sure what your terms are but the question basically wants you to rank the terms based on what power they r to. Standard form in this context = the highest powers to lowest
(Also remember that numbers with no exponents have a invisible 1 hence why -3 is last)
Write the STANDARD FORM of the equation of each line given the Slope and y-intercept.
1) Slope = 8, y-intercept = 3
2) Slope= -2/3, y-intercept = 1
Answers
Answer: See below
Step-by-step explanation:
The basic form of an equation of a straight line in slope intercept form is y=mx+b, where m is the slope and b the y intercept (the value of y when x=0)
1) Slope = 8, y-intercept = 3
y=mx+b: y = bx + 3
2) Slope= -2/3, y-intercept = 1
y=mx+b: y = -(2/3)x + 1

The College Board states that the average math SAT score is 514 with a standard deviation of 117. Colleen gathered data from 50 students in her graduating class and found the average score to be 523. She thinks that her class’s math SAT score is different from the average. Which of the following are the correct null hypothesis and alternate hypothesis? H0: Mu = 514; Ha: Mu greater-than 514 H0: Mu not-equals 514; Ha: Mu = 523 H0: Mu = 514; Ha: Mu not-equals 514 H0: Mu = 514; Ha: Mu = 523.
Answers
From the hypothesis test, we have that:
The null hypothesis is [tex]H_0: \mu = 514[/tex].The alternative hypothesis is: [tex]H_1: \mu \neq 514[/tex]At the null hypothesis, it is tested if her average is the same as the national of 514, hence:
[tex]H_0: \mu = 514[/tex]
At the alternative hypothesis, it is tested if it is different, hence:
[tex]H_1: \mu \neq 514[/tex]
