If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?
Let's see what to do buddy...
____________________________
Reminder:
[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]
So we need to just Multiply above equations like this :
[tex]x + y = 70[/tex]
[tex]x - y = 40[/tex]
[tex](x + y)(x - y) = 70 \times 40[/tex]
[tex] {x}^{2} - {y}^{2} = 2800 [/tex]
____________________________
And we're done.
Thanks for watching buddy good luck.

PLEASEEEE HELPPPP!!!! 50 POINTSSS!!!!!
Answer:
Please check this image for the answer.
Answer:
(x - 5)² + (y -6)² = 9Step-by-step explanation:
Formula for the circle is
(x – h)² + (y – k)² = r²Using the center (5, 6) and radius of 3
(x - 5)² + (y - 6)² = 3²(x - 5)² + (y -6)² = 9I need help simplifying this 7(3/7−6x)

Online, Terrell found a soup recipe that requires 1/4 of a teaspoon of pepper for every 1/2 of a teaspoon of dried basil. For a big event, Terrell wants to make a huge pot of soup. If he uses 1 teaspoon of dried basil, how much pepper should he use?
Answer:
He should use 1/2 of a teaspoon of pepper.
Step-by-step explanation:
From the question, the soup recipe requires 1/4 of a teaspoon of pepper for every 1/2 of a teaspoon of dried basil.
Now, to determine how much pepper Terrell should use if he uses 1 teaspoon of dried basil for the huge pot of soup,
Let the quantity be x
If 1/4 of a teaspoon of pepper requires 1/2 of a teaspoon of dried basil,
then, x teaspoon of pepper will require 1 teaspoon of dried basil
x = (1/4 × 1) ÷ (1/2)
x = 1/4 ÷ 1/2
x = 1/4 × 2/1
x = 2/4
x = 1/2
∴ 1/2 of a teaspoon of pepper is required for 1 teaspoon of dried basil.
Hence, he should use 1/2 of a teaspoon of pepper.

Veronica is given a rectangular piece of paper. If the length of Veronica's piece of paper is represented by x2 + 6x – 2 and the width is represented by 3x - 5, find the area of the piece of paper.
Answer:
3x^3 +13x^2 - 36x + 10.
Step-by-step explanation:
Area = length * width
= (3x - 5)(x^2 + 6x - 2)
= 3x(x^2 + 6x - 2) - 5)(x^2 + 6x - 2)
= 3x^3 + 18x^2 - 6x - 5x^2 - 30x + 10
= 3x^3 + 13x^2 - 36x + 10.
What part of an equation represents the constant rate of change?
Answer:
equation written in the form Ax + By = C where A and B are coefficients and C is the constant. assigns each input value, one output value. rate that describes how one quantity changes in relation to another quantity. rate of change between any two quantities is the same, or constant.
Step-by-step explanation:
The Slope of the equation represents the constant rate of change.
For example: in the equation [tex]y=3x+9[/tex] [tex]3[/tex] is the slope
The explicit rule for a sequence and one of the specific terms is given. Find the position of the given
term
f(n) -5.5n - 52;25
25 is the BLANK th term
Answer:
25 is the 14th term.
Step-by-step explanation:
The nth term of a sequence is given by the following explicit rule:
f(n) =5.5n - 52
We need to find the position n of the term of value 25. In other words, find n in the equation:
5.5n - 52=25
Adding 52:
5.5n =25+52=77
Solving:
n=77/5.5
n=14
25 is the 14th term.

Write an equation of the line passing through the point (7, 3) that is parallel to the line 4x−7y=9.
Answer:
The equation of the line is y = 4x/7 - 1
Step-by-step explanation:
The equation of a straight line can be represented by
y = mx + c
where m represents the slope and c represents the y-intercept
So for;
4x - 7y = 9
7y = 4x - 9
y = 4x/7 - 9/7
The slope here is 4/7
Since the line we are trying to form is parallel, then the slope of the line is 4/7 also, since parallel lines have equal slope
So the equation of the new line will be;
y = 4x/7 + c
To get c, just put the point x = 7 and y = 3
3 = 4/7(7) + c
3 = 4 + c
c = 3-4
c = -1
So the equation of the line is;
y = 4x/7 - 1

Answer:
RHS
Step-by-step explanation:
It is given that XY is the perpendicular bisector of WZ. This means that it forms 90-degree angles at Y. (angle XYZ and angle XYW are 90 degrees). (R)
Since there is a right angle at Y, XZ and XW are the hypotenuses. (H)
There is a common line between triangle XYZ and XYW and that is XY. (S)
Therefore you can prove ΔXYZ ≅ΔXYW because of RHS

Tina is saving to buy a notebook computer. She has two options. The first option is to put $300 away
initially and save $30 every month. The second option is to put $200 away initially and save $50 every
month. After how many months would Tina save the same amount using either option? How much
would she save with either option?
Plzzz hellpppp
Answer:
After 5 months, she will save the same amount using either option.
She would have saved $450 with either option.
Step-by-step explanation:
Set up expressions to represent the amount of money saved for each saving option, where x is the number of months
The first one can be represented by 30x + 300
The second one can be represented by 50x + 200
Set these equal to each other and solve for x:
30x + 300 = 50x + 200
300 = 20x + 200
100 = 20x
5 = x
So, after 5 months, Tina will save the same amount of money with both options.
To find how much she will save, plug in 5 as x into either expression:
30x + 300
30(5) + 300
150 + 300
= 450
So, she would have saved $450 with either option.
