This is just the difference of squares.
The expression [tex]X^2 - y^2[/tex] can be factored using the difference of squares rule, resulting in the Factoring form [tex](X - y)(X + y)[/tex].
The equation you're asking about, [tex]X^2 - y^2[/tex], is an example of a difference of squares, a key concept in algebra. In general, the formula [tex]a² - b²[/tex] can be factored into [tex](a - b) (a + b)[/tex]. So for the expression [tex]X^2 - y^2[/tex], we can apply this rule to factor it into [tex](X - y)(X + y)[/tex].
Here is a step-by-step explanation:
Identify that the equation is in the form of [tex]a²-b²[/tex], where 'a' is X and 'b' is y

The 1 copy makes the cost equivalent in two options and the cost of 1 copy is $41.
Step-by-step explanation:
The given information are that,
Elsa could use a printer in which it cost a $38 setup fee and $3 for each copy.
Elsa could go to a supply store in which it cost $36 up-front fee and $5 for each copy.
To find the same amount for certain number of copies in both the cases :
Let us assume that the number of copies be 'x'.
In the first case, the total cost will be = setup fee + cost for x copies.
⇒ Total cost = 38 + 3x
In the second case, the total cost will be = up-front fee + cost for x copies.
⇒ Total cost = 36 + 5x
To find the x value :
Equating the total cost of both the cases, we get
⇒ 38 + 3x = 36 + 5x
⇒ 38-36 = 5x-3x
⇒ 2 = 2x
⇒ x = 1 copy
Therefore, taking 1 copy make the two options equivalent in terms of cost.
The cost of 1 copy = 38+ 3(1) = 41 dollars.
Therefore, it would cost $41 for 1 copy.

Mary mixes white paint and blue paint in the ratio 2:3
She makes a total of 20 litres of paint.
How much more blue paint does she need to add to the mixture so that the ratio of white paint to blue paint becomes 1:7?
Given:
Ratio of white and blue paint is 2:3
Total quantity of paint is 20 litres
To find:
Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7
Solution:
The ratio 2:3 totals 20 that is [tex]2x+3x=20\rightarrow5x=20\rightarrow x=4[/tex]
So, the quantity of white paint in the mixture is [tex]2\times4=8[/tex] and the quantity of blue paint in the mixture is [tex]3\times4=12[/tex]
Now, to get the final ratio as 1:7, Mary should have [tex]7\times8=56 \text{ litres }[/tex] of blue paint. So, she need to add [tex]56-12=44 \text{ litres}[/tex].
Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

A cyclist can cover a distance of 18 miles in 45 minute. How many miles the cyclist can cover in 6 hours?
First, lets find how many miles the cyclist can ride per minute (speed = distance/time).
18/45 = 0.4 miles per minutes
Second, lets find how many miles the cyclist can ride per hour.
0.4 * 60 = 24 miles per hour
Third, lets find how many miles teh cyclist can ride in 6 hours.
24 * 6 = 144 miles in 6 hours

John is saving $6 a week. He has already saved $28. How many weeks will it take John to reach his goal of $100?
Answer:
12 weeks
Step-by-step explanation:
If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72
In one week → $6
2 weeks → $12
3 weeks → $18
and so on..
[tex]\frac{72}{6} = 12[/tex]
John will need 12 more weeks to save a total of $100.

Find the equation of a line that passes through the point
(0,7) with a slope that is the opposite of the slope of the
line with equation y = -x -5.
Answer:
y=x+7
Step-by-step explanation:
y-7=1(x-0)
y-7=x-0
y=x+7
Answer:
y=x+7
Step-by-step explanation:
You need a slope that is opposite the slope of equation y=-x-5. To do this you need to find the opposite reciprocal. For -1, the opposite reciprocal would be 1. So, your slope is going to be 1.
You need the line to pass through (0,7), which is a point on the y axis. b in y=mx+b is the y-intercept. So, you would make 7 your b.
By plugging in these numbers you end up with y = x + 7

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need to drive 240 miles?
Answer:
34
Step-by-step explanation:
ok so first you need to divide 144 by 12 = 12
then you need to figure if you split that in half it equals 6.
now we know that for every 12 miles you drive, you need 1 gallon of gas
now you need to divide 240 by 6 = 40
so you will need 40 gallons of gas to drive that far
we are not one yet, then you need to take away 6 from 40 witch comes to 34.
so you will need 34 more gallons of gas

8 g + 10 = 35 + 3 g
Answer:
g = 5
Step-by-step explanation:
8 g + 10 = 35 + 3 g
in order to get the value of g, firt of all rearrange the expression or in ither words collect the like terms.
8 g + 10 = 35 + 3 g
8g + 10 - 3g = 35
NOTE; when you are moving a number with positive sign across the equal to = sign the positive changes to negative and same thing applies to the negative sign it changes to positive sign.
we have;
8g -3g = 35 - 10
5g = 25
divide both sides by 5
5g/5 = 25/5
g = 5

We have to find the range of the given function.
Range of function
Range is the collection of all possible values of y for the domain of function.Range of basic sine function is

Question:
A rectangular prism has a length of 4 1/2 millimeters, a width of 4 1/2 millimeters, and a height of 6 millimeters.
Sally has a storage container for the prism that has a volume of 143 cubic millimeters.
What is the difference between the volume of the prism and the volume of the storage container?
Answer:
The difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter
Solution:
Volume of rectangular prism is given as:
[tex]volume = length \times width \times height[/tex]
From given,
[tex]length = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\width = 4\frac{1}{2} = \frac{9}{2}\ mm\\\\height = 6\ mm[/tex]
Therefore,
[tex]volume = \frac{9}{2} \times \frac{9}{2} \times 6 = 121.5\ mm^3[/tex]
Sally has a storage container for the prism that has a volume of 143 cubic millimeters
What is the difference between the volume of the prism and the volume of the storage container
Difference = 143 - 121.5 = 21.5
Thus difference between the volume of the prism and the volume of the storage container is 21.5 cubic millimeter

The sum of two numbers is 47 and the difference is 19. What are the numbers?
Answer: The two numbers are 33 and 14
Step-by-step explanation: We shall start by first assigning letters to unknown variables. Therefore let the two numbers be called a and b. The first clue in this question states that the sum of both a and b equals 47. That means we can write the expression;
a + b = 47.
The second clue states that their difference equals 19. This also can be expressed as follows;
a - b = 19
Now we have a pair of simultaneous equations which are
a + b = 47 ———(1)
a - b = 19 ———-(2)
We shall use the substitution method. Therefore from equation (1), make a the subject of the equation.
a = 47 - b
Next we substitute for the value of a in equation (2)
a - b = 19
47 - b - b = 19
47 -2b = 19
By collecting like terms we now have 47 - 19 = 2b
28 = 2b
Divide both sides of the equation by 2
14 = b
We can now substitute for the value of b into equation (1)
a + b = 47
a + 14 = 47
Subtract 14 from both sides of the equation
a = 33.
Therefore the two numbers are 33 and 14.
The two numbers with a sum of 47 and a difference of 19 are 33 and 14. We found this by setting up two equations based on the given information and solving for the two variables.
Explanation:The sum of two numbers is 47 and the difference is 19. To find these two numbers, we can set up a system of equations and solve them. Let the numbers be x and y.
x + y = 47 (equation 1)x - y = 19 (equation 2)Adding both equations, we get 2x = 66, hence x = 33.
Substituting x in equation 1, we get 33 + y = 47, hence y = 47 - 33 = 14.
Therefore, the two numbers are 33 and 14.

If y = 6
4x - 3 x 6 = 6 - 12

Add 18 to both sides
4x - 18 + 18 = -6 + 18
4x = 12
Divide both sides by 4
