A student received a coupon for 20% off the total purchase price at a clothing store. Let y be the
original price of the purchase. Use the expression below for the new price of the purchase. Write
an equivalent expression by combining like terms.
y-0.2y
Answer: 0.8y
Step-by-step explanation:
Original price of purchase = y
Since the received a coupon for 20% off the total purchase price at a clothing store, the expression for the new price will be:
= y - (20% × y)
= y - (0.2 × y)
= y - 0.2y
= 0.8y
The equivalent expression is 0.8y.

when 3 times a number is added to it's square the total is 18
Answer:
x(the number)=3
Step-by-step explanation:
3×3+3squared = 18
Answer:
3x + x^2 = 18
x^2 + 3x - 18 = 0
(x + 6)(x - 3) = 0
x + 6 = 0
x = -6
x - 3 = 0
x = 3

1. 4(1/2x + 2) = 6
Answer:
4(1/2x + 2) = 6
1/2 x+2=6/4
1/2 x=3/2-2
1/2 x=(3-4)/2
x=-1/2×2=-1 is your answer
Answer:
-1 is your answer :)
Step-by-step explanation:
4(1/2x + 2) = 6
1/2 x+2=6/4
1/2 x=3/2-2
1/2 x=(3-4)/2
x=-1/2×2= -1
The length of a rectangle is 16 inches longer than its width. If the perimeter of the rectangle is 540 inches, what is the length in inches?
Answer: 143
Step-by-step explanation:
The length and width of the rectangle will be 143 inches and 127 inches, respectively.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The length of a rectangle is 16 inches longer than its width. If the perimeter of the rectangle is 540 inches. Then the equations are given as,
L = 16 + W ...1
540 = 2(L + W) ...2
From equations 1 and 2, then we have
540 = 2(16 + W + W)
270 = 16 + 2W
2W = 254
W = 127 inches
Then the length of the rectangle is given as,
L = 16 + 127
L = 143 inches
The length and width of the rectangle will be 143 inches and 127 inches, respectively.
More about the perimeter of the rectangle link is given below.

if the sum of two expressions is 3x+5 and one expression is 5x-7 what is the other expression
Answer:
-2x + 12
Step-by-step explanation:
If we call our other expression y, we can set up an equation tying together 3x + 5, y, and 5x - 7:
[tex](5x-7)+y=3x+5[/tex]
Solving for y by subtracting 5x - 7 from both sides will get us the expression we're looking for:
[tex]y=3x+5-(5x-7)\\y=3x+5-5x+7\\y=-2x+12[/tex]
So the other expression in the sum is -2x + 12.

Sampling
This is a common statistics practice, when we want to study something from a population, we find a sample of this population. This sample has to be representative.
In this question:
Students in the seventh grade prefer to visit the aquarium or the science museum for their end-of-year trip.
So the sample would have to contain only students from the seventh grade. So the correct options are:
10 seventh-grade boys and 10 seventh-grade girls
25 seventh-grade students

By what percent will a fraction increase is decreased by 10% and its denominator is decreased by 50%
Answer:
Let's assume the fraction is 1/1
decreasing 1 by 10% = .9
decreasing 1 by 50% = .5
So the fraction becomes .9/.5 = 1.8
So its value increases by 180%

Identify the requirements for a discrete probability distribution. Choose the correct answer below. A. There must be a fixed number of independent trials. There must be two mutually exclusive outcomes for each trial with a constant probability of success. B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive. C. Each probability must be between zero and one inclusive. D. The sum of the probabilities must equal one.
Answer:
B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive
Step-by-step explanation:
The discrete probability distribution is a distribution in which the random variable would be considered as countable i.e. non-negative digits also it would be presented in table form
So according to the given situation, the option b is correct as their sum would be equivalent to zero also each probability should be lies between zero and one inclusive
Calculus I: Find the smaller and larger x value.
Answers:
Smaller x value = -3Larger x value = -1===============================================================
Explanation:
Apply the derivative (see attached image for the steps)
You should get [tex]\frac{dy}{dx} = -\frac{1}{(x+2)^{2}}\\\\[/tex]
The line y = x is really y = 1x+0. We see that it's in the form y = mx+b with m = 1 as the slope. The negative reciprocal of this is m = -1, which is the perpendicular slope. As a rule, any two perpendicular lines always have their slopes multiply to -1 as long as neither line is vertical or horizontal.
So we want the derivative we just found to be set equal to -1, that way we have the x value lead to this derivative slope value.
We want dy/dx = -1
In short, the equation we need to solve is [tex]-\frac{1}{(x+2)^{2}} = -1\\\\[/tex]
Let's solve for x
[tex]-\frac{1}{(x+2)^{2}} = -1\\\\\frac{1}{(x+2)^{2}} = 1\\\\(x+2)^{2} = 1\\\\x+2 = \pm\sqrt{1}\\\\x+2 = \pm1\\\\x+2 = 1 \ \text{ or } \ x+2 = -1\\\\x = -2+1 \ \text{ or } \ x = -2-1\\\\x = -1 \ \text{ or } \ x = -3\\\\[/tex]
The smaller x value is -3 while the larger x value is x = -1.
Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car after x years, which function represents the car’s value?
f(x) = 20,000(0.85)x
f(x) = 20,000(0.15)x
f(x) = 20,000(1.15)x
f(x) = 20,000(1.85)x
Answer:
f(x) = 20,000(0.85)^x
Step-by-step explanation:
Given data
Cost of car P= $20,000
rate of depreciation r= 15%
Let us apply the depreciation formula
f(x) = P(1-r)^t
substitute
f(x) = 20000(1-0.15)^x
f(x) = 20000(0.85)^x
Therefore the correct expression is option 1
f(x) = 20,000(0.85)^x
