#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?

Each chef at "Sushi Emperor" prepares 15 1515 regular rolls and 20 2020 vegetarian rolls daily. On Tuesday, each customer ate 2 22 regular rolls and 3 33 vegetarian rolls. By the end of the day, 4 44 regular rolls and 1 11 vegetarian roll remained uneaten. How many chefs and how many customers were in "Sushi Emperor" on Tuesday?
Answer:
2 chefs and 13 customersStep-by-step explanation:
Let the number of chefs is x and the number of customers is y.
Regular rolls
Prepared 15x, eaten 2y, left 4Equation:
15x = 2y + 4 >>> (1)Vegetarian rolls
Prepared 20x, eaten 3y, left 1Equation:
20x = 3y + 1 >>> (2)We have a system.
Solve it by elimination, multiply the first one by 4 and the second one by 3:
15x*4 = 2y*4 + 4*4 ⇒ 60x = 8y + 1620x*3 = 3y*3 + 1*3 ⇒ 60x = 9y + 3Compare the equations:
8y + 16 = 9y + 39y - 8y = 16 - 3y = 13Substitute the value of y into first equation and solve for x:
15x = 2*13 + 415x = 30x = 2Answer:2 Chefs and 13 customers.

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.
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.

What is the area of this triangle? A=B x H 12
Height= 127 ft
Base= 13ft
Answer:
The area of this triangle is 825.5 square feet
Step-by-step explanation:
For a given Triangle
Base = 13 ft
Height = 127 ft
Now, Area of Triangle
A = ½ × b × h
A = ½ × 13 × 127 ft
A = ½ × 1751 ft
A = 825.5 square feet

3. Bridget is reviewing a nutrition label. She
wants to find the difference between the
amount of grams of saturated fat and
protein. How many more grams are there of
saturated fat than protein? Draw decimal
models to find the difference.
The difference between the amount of saturated fat and protein can be calculated using the subtraction operation. Hence, the difference is 0.59 grams.
Given the Parameters :
Grams of Saturated Fat = 1.08 grams Grams of protein = 0.49 gramsUsing the subtraction operation :
Grams of Saturated Fat - Grams of Protein 1.08 g - 0.49 g = 0.59 gramsHence, the amount of saturated fat is 0.59 grams more than Protein.

What are the blank numbers for 16, 17, 18, and 19
Answer:
16: 0.5, 5, 7.5
17: 62, 434, 682
18: 12.3, 62.5, 10
19: 1, 75, 300
Step-by-step explanation:
16: 9/18=0.5 so halve the numbers
17: 186/3=62 so multiply numbers by 62
18: 24.6/2= 12.3 so multiply by 12.3 and divide for the last one
19: 125/5=25 so for the first one divide by 25 and for the last two times by 25
Solve the system of equations.
y = x2 - 3x + 6
y = 2x + 6
A. (0,6) and (5, 16)
B. (-5, - 4) and (0,6)
C. (-5, - 4) and (0-6)
D. (0,-6) and (5, -16)
Step-by-step explanation:
y = x² - 3x + 6
y = 2x + 6
y = y
x² - 3x + 6 = 2x + 6
x² - 5x = 0
x(x - 5) = 0
x = 0 and x = 5
y = 2x + 6 and y = 2x + 6
y = 2(0) + 6 and y = 2(5) + 6
y = 0 + 6 and y = 10 + 6
y = 6 and y = 16
(x1,y1) and (x2, y2) = (0,6) and (5,16)

Is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer.
Please use your own words im not tryna get in trouble.
Answer:
No, the two triangles can not be proven to be congruent with the given information. The reason that it can't be proven is due to there being a missing measurement. The triangles could be proven to be congruent if there was an angle given or if the other side was shown to be congruent.

Answer:
132.3
Step-by-step explanation:
A= 2 π r h+2 π r²
A=2×3.14×3×4+2×3.14×3²
A=6.3×3×4+6.3×9
A=75.6+56.7
A=132.3
(π is rounded up to 3.14)
NOTE:
The answer might defer from the calculator answer (which is 131.9) and that is because the value of pi taken by the calculator is the whole value and here it is rounded up to 3.14 which is what you take when calculating manually
