x^2 - 2xy + y^2
(Im not sure if it's correct)
Hope it helps.
Have a nice day noona/hyung.
Answer:
x²-2xy+y²
Step-by-step explanation:
(x-y)² is the same as (x-y)(x-y).
First you would do x×x=x²
Then you would do x×-y= -xy
After that you do -y×x= -xy
Then do -y×-y= y²
You would then put it into an equation like this:
x²-xy-xy+y²
And then simplify it to:
x²-2xy+y²
Hope this helps :)
At the local store, the cost of 1 pair of jeans is $24 and the cost of 3 pairs is $24 × 3 = $72. At the online store, the cost of 2 pairs of jeans is ($22 × 2) + $6 = $50 and the cost of 3 pairs is ($22 × 3) + $6 = $72.
Complete question :
Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and
ignore any taxes.
Answer:
$24, $72
$50
Step-by-step explanation:
From the table :
At local store :
2 pair of jeans cost $48
Cost of a pair :
Cost of 2 pairs / number of pairs
$48 / 2 = $24
Cost of 3 pairs :
Cost per pair * number of pairs :
$24 * 3 = $72
At online store :
Cost of Jean include a fixed fee of $6
Cost of one pair of Jean = $28
Actual cost of Jean :
$28 - $6 = $22
Hence, cost of 2 pair of jeans:
($22*2) + $6
$44 + $6 = $50
2/3x^2+15=23
help please
Answer:
x= 4.2
Step-by-step explanation:
2/3x^2=23-15
2/3x^2=8
Sq. root both sides
2/3x = 2.8
multiply both sides by 3
2x= 8.4
divide both sides by 2
x= 4.2
Each side of a square classroom is 8 yards long. The school wants to replace the carpet in the classroom with new carpet that costs $79.38 per square yard. How much will the new carpet cost?
Answer:
Total cost= $4,445.28
Step-by-step explanation:
Giving the following formula:
Each side of a square classroom is 8 yards long.
The new carpet costs $79.38 per square yard.
First, we need to calculate the total number of square yards needed:
Square yards of the classrom= 8*8= 56
Now, the total cost:
Total cost= total square yards*unitary cost
Total cost= 56*79.38
Total cost= $4,445.28
A caterer is preparing a dinner for a party. Shecharges an initial fee of $16 and $8.25 per person. How manypeople can attend a dinner that costs $131. 50? Write an equationand solve.
Answer:
The nomber of people can attend a dinner that costs $131. 50 is 14.
Step-by-step explanation:
With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:
c=16+8.25x, where:
c is the total cost of he dinner
x is the number of people
Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:
131.50=16+8.25x
131.50-16=8.25x
115.50=8.25x
x=115.50/8.25
x=14
According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.

Welcome for the answer. This answer is for good intentions only please don't report unless necessary. Have a great rest of your day!if f(x) = 2x -3 what is the value of f(x) when x is -5?
Answer:
-13
Step-by-step explanation:
To find the value of f(x) when x is -5, substitute -5 for the x in the equation. Then, simplify:
[tex]f(x) = 2x-3\\\\f(-5) = 2(-5)-3\\f(-5) = -10-3\\f(-5) = -13[/tex]
So, when x is -5, the value of f(x) will be -13.

Find the side lengths of a triangle
Step-by-step explanation:
The spinner below is spun. Find the probability that it lands on an odd number, given that it lands on a white space.
The probability that the spinner lands on an odd space given that it lands on the white space is 3/8.
The question is incomplete and the possible question is
The spinner given in the below image is spun. Find the probability that it lands on an odd number, given that it lands on white space.
What is Conditional Probability?The conditional probability of an event B on the hypothesis that another event A has occurred will be denoted by P(B|A) and defined by
P(B|A)=P(AB)/P(A)
provided P(A)≠0.
In case P(A)=0, the conditional probability remains undefined.
How to tackle the problem?The sample space has 16 events, out of which 8 events have white space.
And out of those 8 white spaces, 3 have odd numbers.
White events are 12,14,6,2,10,15,3,9.
White odd events are 3,9,15.
Hence, P(White odd)=3/16
P(White)=8/16=1/2
Thus, the probability that the spinner lands on an odd space given that it lands on the white space
=P(odd | White)
=P(White odd) / P(White)
=(3/16)/(1/2)
=3/8
Hence, the probability that the spinner lands on an odd space given that it lands on the white space is 3/8.

Han's garden has an area of 193.75
square feet. If the length of the garden
is 12.5 feet, what is the width
Answer:
15.5
Step-by-step explanation:
The equation to find area is Length × Width= Area
we have the area and the length, 12.5 × width= 293.75
to find the width, you will have to reverse engineer and divide the area by the length instead.
193.75 ÷ 12.5 =15.5
just to double check, 15.5 × 12.5 = 193.75
the width is 15.5

A family buys 6 airline tickets online. The family buys travel insurance that costs
total cost is $1,014. Let x represent the price of one ticket. Write an equation for t
find the price of one ticket.
Answer:
6x + 102 = 1,140
Step-by-step explanation:
We're looking for the sum. The insurance cost 17 dollars per ticket, and there are 6 tickets, so we have to multiply. 17 times 6 is 102. Next, we subtract 102 from both sides. 6x = 1,038. Then, divide by 6. x = 173. So, one ticket costs 173. I don't know if the insurance is included, but if it is, then add 17 and you get 190.
A system of equations is shown below. y=-x+3 y=3-/2 Does the ordered pair (-4, 6) satisfy the system? Justify your answer.
Answer:
(2.5, 5.5)
Step-by-step explanation:
The system of equation is not well written
Let the system of equations be;
y = x+3
y = 3x - 2
Equate both expressions to get x;
x + 3 = 3x - 2
x - 3x = -2-3
-2x = -5
x = 5/2
x = 2.5
Get the value of y;
y = x+3
y = 2.5+3
y = 5.5
Hence the required coordinate point is (2.5, 5.5)
Note that the second equation was assumed but the same steps can be taken to solve the given equation

what is g(x)?
a- g(x)=-x^2
b- g(x)=-lxl
c- g(x)=-2^x
d- g(x)=-x
Answer:
g(x) = -2^x
Step-by-step explanation:
This is an exponential function from the looks of the value for x as it decreases toward the negative value (increase in the absolute value calculation) y is constricted from its vigorous values down to the fractional components of an equation of the standard appearance of y = C^x. For this, try some values. x = 1 y = 2, x = 2 y = 4. There is a trend that is established through these points, and g(x) = -2^x seems to follow this trend as it is reflect across the x-axis. Enter points, it is confirmed and a graphing calculator further substantiates. Try for yourself!
