A movie theater sends out a coupon for 25% off the price of a ticket. Write an equation for the situation, where y is the price of the ticket with the coupon, and x is the original price of the ticket. Use pencil and paper. Draw a graph of the equation and explain why the line should only be in the first quadrant.
The equation is y =__
(Use integers or decimals for any numbers in the expression).
Answer:
Step-by-step explanation:
x-the original price
y- the discounted price
y= the original price - 25 % discounted from x = x- (.25*x) = x( 1-.25) = .75x
equation is y= .75x
The equation should only be in the first quadrant because the prices can only be positive numbers.
What is the y-intercept of the graph represented by the equation below?

7.5% of the grade has green eyes if there are 120 students in the grade how many dont have green eyes
Answer:
Step-by-step explanation:
If 7.5 % has green eyes, then 92.5% (the complement given by 100%-7.5%) dont have green eyes. 92.5% of 120 is given by
0.925*(120)=111
111 students in the grade dont have green eyes.
Find the slope of the line.
Answer:
slope = [tex]\frac{-1}{5}[/tex]
Step-by-step explanation:
Find the slope of the line using the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. The formula requires two points from the line - and looking at the graph, (1, 10) and (6, 9) are two points the line passes through (but any other points the line also passes through would work fine, too). So, substitute the points' x and y values into the formula and solve:
[tex]\frac{(9)-(10)}{(6)-(1)} \\= \frac{-1}{5}\\[/tex]
Therefore, [tex]-\frac{1}{5}[/tex] is the slope.

Answer:
d) n^2 + n
Step-by-step explanation:
so n consists of two blocks. in stage two, n doubles into four blocks and there are two other blocks as well. n doubling indicates that n is squared, and because n consists of two blocks, n is just added to stage two, so stage two consists of six blocks. (i hope this makes sense..)

Solve for x. Your answer must be simplified. x/24>5
Answer:
x > 120
Step-by-step explanation:
Answer:
we conclude that:
[tex]\frac{x}{24}>5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>120\:\\ \:\mathrm{Interval\:Notation:}&\:\left(120,\:\infty \:\right)\end{bmatrix}[/tex]
The solution graph is also attached.
Step-by-step explanation:
Given
The inequality is given by
[tex]\frac{x}{24}>5[/tex]
To determine
Solve for x
Given the inequality
[tex]\frac{x}{24}>5[/tex]
Multiply both sides by 24
[tex]\frac{24x}{24}>5\cdot \:24[/tex]
Simplify
[tex]x>120[/tex]
Therefore, we conclude that:
[tex]\frac{x}{24}>5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>120\:\\ \:\mathrm{Interval\:Notation:}&\:\left(120,\:\infty \:\right)\end{bmatrix}[/tex]

Find the value of the following: 11!8!/12!6!
If your answer is not an integer, write it as an exact fraction.
Answer:
14/3
Step-by-step explanation:
[tex]\frac{11*10*9*8*7*6*5*4*3*2*8*7*6*5*4*3*2}{12*11*10*9*8*7*6*5*4*3*2*6*5*4*3*2}[/tex]
You have this huge fraction and basically what you do is you cancel out all the numbers that are on the top and the bottom so it would be:
[tex]\frac{7*8}{12}[/tex]
Now, you can just simplify this: 56/12 = 14/3

If the polynomials ax^3 + 4x^2 + 3x - 5 and x^3 - 3x^2 - 5x + a leave the same remainder when divided by (x-3) and (x+2) respectively, find the value of a.....
Given:
The polynomials [tex]ax^3+4x^2+3x-5[/tex] and [tex]x^3-3x^2-5x+a[/tex] leave the same remainder when divided by (x-3) and (x+2) respectively.
To find:
The value of a.
Solution:
Remainder theorem: If a polynomial p(x) is divided by (x-c), then the remainder is equal to p(c).
The polynomials [tex]f(x)=ax^3+4x^2+3x-5[/tex] is divided by (x-3). So, the remainder is f(3).
[tex]f(3)=a(3)^3+4(3)^2+3(3)-5[/tex]
[tex]f(3)=27a+36+9-5[/tex]
[tex]f(3)=27a+40[/tex]
The polynomial [tex]g(x)=x^3-3x^2-5x+a[/tex] is divided by (x+2). So, the remainder is g(-2).
[tex]g(-2)=(-2)^3-3(-2)^2-5(-2)+a[/tex]
[tex]g(-2)=-8-12+10+a[/tex]
[tex]g(-2)=-10+a[/tex]
It is given that the remainders are same. So,
[tex]f(3)=g(-2)[/tex]
[tex]27a+40=-10+a[/tex]
[tex]27a-a=-10-40[/tex]
[tex]26a=-50[/tex]
Divide both sides by 26.
[tex]a=\dfrac{-50}{26}[/tex]
[tex]a=\dfrac{-25}{13}[/tex]
Therefore, the value of a is [tex]\dfrac{-25}{13}[/tex].
