Answer:
48 students total in the school play
Ratio of boys to girls is 5:7
How many more girls are there than boys in the play?
Let's let "5x" represent the number of boys in the school play and "7x" represent the number of girls in the school play.
5x = boys
7x = girls
If we know that the total number of students in the play equals 48, then that must me that both the number of boys and girls combined must equal 48:
5x + 7x = 48
12x = 48
x = 4
Now, take your x-value and plug it into both the boys' and girls' values to figure out how many boys and girls there are in the play:
5x = 5 (4) = 20 boys
7x = 7 (4) = 28 girls
To find out how many more girls there are than boys in the play, just subtract the number of girls minus the number of boys:
# girls - # boys = 28 - 20 = 8
This means that there are 8 more girls than boys in the school play.

The sequence below represents Marisa’s fine at the library for each day that she has an overdue book:
$0.50, $0.65, $0.80, $0.95, $1.10, ...
Which equation represents Marisa’s library fine as a function of a book that is n days overdue?
f(n) = 0.15n
f(n) = 0.50n
f(n) = 0.15n + 0.35
f(n) = 0.50n + 0.15

Given: Triangle ABC with vertices A(5,-2), B(5.-7), and C(1, -2). Which set of
coordinates best repositions the triangle to make a coordinate proof easier?
Answer: C (0,0), (-4,0) and (0, -5)
Step-by-step explanation:
After repositioning the triangle, the vertices will be A(0, 0), B(0, -5), and C(-4, 0). This new positioning will make the coordinate proof easier since the coordinates are now simpler, and one vertex is located at the origin, which often simplifies the calculations in coordinate geometry proofs.
To make a coordinate proof easier, it's helpful to reposition the triangle in a way that simplifies the calculations and coordinates. In this case, you can reposition the triangle by translating it so that one of its vertices aligns with the origin (0, 0). This process is known as translation.
Let's reposition the triangle so that vertex A(5, -2) aligns with the origin (0, 0). To do this, we need to subtract the x-coordinate of vertex A from all the x-coordinates of the other vertices and subtract the y-coordinate of vertex A from all the y-coordinates of the other vertices.
The new coordinates for the repositioned triangle will be:
A(5, -2) -> A(0, 0) (remains the same, as it aligns with the origin)
B(5, -7) -> B(5 - 5, -7 - (-2)) -> B(0, -5)
C(1, -2) -> C(1 - 5, -2 - (-2)) -> C(-4, 0)

PLEASE HELP MEEEEE THIS IS SO HARDDD
Answer:
B and $684
Step-by-step explanation:
B, because wednesday is three days after sunday so 4 times 3 because she walks 4 more laps each day until saturday. Add the 24 laps she already walks 4(3)=12+24=36
By saturday she would've walked 48 laps, so 48 times 3 for the 3 dollars each lap. 48(3)=144 now u have to find the other days so the equation you would use is 3(24 + 4x), x for the day until saturday. 3(24+4(1))=3(28)=84,just do that for each day and then add all them together because the question asked by the end of the week, saturday, how much money so yea. 84+96+108+120+132+144=684
(honestly u could just keep adding 12 to the previous number as that's what it's increasing by.) haha rlly hope I'm not wrong on the second one. Have a nice day!

Find the equation of the quadratic function with vertex (-2,18) passing through (-5,0)?
Answer:
[tex]y-18=-2(x+2)^2[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y-k=a(x-h)^2[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
It's been given the vertex of the parabola as (-2,18):
[tex]y-18=a(x+2)^2[/tex]
Now substitute the point (-5,0) and find the value of a:
[tex]0-18=a(-5+2)^2[/tex]
Operating:
[tex]-18=a(-3)^2[/tex]
[tex]-18=9a[/tex]
Solving for a:
[tex]a = -18 / 9[/tex]
a = -2
Thus, the equation of the quadratic function is:
[tex]\mathbf{y-18=-2(x+2)^2}[/tex]

What is the reflected image in the x-axis A(- 1, 8), B(- 8, 8) C(- 5, 1) ?
Answer:
[tex]A' = (- 1, -8)[/tex]
[tex]B' = (-8, -8)[/tex]
[tex]C' = (-5, -1)[/tex]
Step-by-step explanation:
Given
[tex]A = (- 1, 8)[/tex]
[tex]B = (-8, 8)[/tex]
[tex]C = (-5, 1)[/tex]
Required
Determine the reflected image in the x axis
When a point is reflected across the x axis, the x coordinate remains the same, while the y coordinate is negated.
In other words,
[tex]A(x,y)[/tex] when reflected becomes [tex]A'(x,-y)[/tex]
So, for each of the following points
[tex]A = (- 1, 8)[/tex]
[tex]B = (-8, 8)[/tex]
[tex]C = (-5, 1)[/tex]
There images are:
[tex]A' = (- 1, -8)[/tex]
[tex]B' = (-8, -8)[/tex]
[tex]C' = (-5, -1)[/tex]
8. Ten friends go out for dinner. The total cost of the meals is $141. Some
friends have three-course meals and the rest have two-course meals. Each
of the three-course meals costs $15 and each of the two-course meals
costs $12. The number of people who have three-course meals is x, so the
number of people who have two-course meals is 10 - x. How many three
course meals are possible?
2 three-course meals
20 three-course meals
e
7 three-course meals
5 three-course meals
Answer:
7 three-course meals
Step-by-step explanation:
7 x 15= 105
141-105= 36
36/12= 3
7+3= 10
So total, there are 10 meals; 7 three-course and 3 two-course

Solve (x-4)^2 = 5
A. x= 4 +- square of 5
B. x= 9 and x= -1
C. x= 5 +- square of 4
D. x= -4 +- square of 5
Answer:
A
Step-by-step explanation:
Assuming you mean the square root of five, then the answer is A.
You start by taking the square root of both sides.
√(x - 4)^2 = ±√5
x - 4 = ±5
x = 4 ±5

What is the solution for x in the equation?
9x - 20 - 4x = 40?
X=1/4
X=4
X=12
X=1/12
Answer:
x = 12
Step-by-step explanation:
9x - 20 - 4x = 40
Combine like terms
5x -20 = 40
Add 20 to each side
5x -20+20 = 40+20
5x = 60
Divide by 5
5x/5 = 60/5
x = 12
9x - 20 - 4x = 40
By transposition method, we get
9x - 4x = 40 + 20
By simplifying the like terms, we get
5x = 60
or, x = 60/5 = 12
The value of x is 12.
