Answer:

Step-by-step explanation:
Use the system of equations to answer the question.
2x + 3y = 8
x-y=5
Answer:
x = 23/5
y = -2/5
Step-by-step explanation:
We are given two equations
2x + 3y = 8 eq. 1
x - y = 5 eq. 2
From eq. 2
x - y = 5
x = 5 + y eq. 3
Substitute eq. 3 into eq. 1
2x + 3y = 8 eq. 1
2(5 + y) + 3y = 8
Simplify the equation
10 + 2y + 3y = 8
10 + 5y = 8
5y = 8 - 10
5y = -2
y = -2/5
or
y = -0.4
Substitute the value of y into eq. 3 to get the value of x
x = 5 + y eq. 3
x = 5 - 2/5
x = 23/5
or
x = 4.6
Therefore, the solution set is
(x, y) = (23/5, -2/5)
This is the point of intersection where these two equations meet.

Answer:
She wronged in V1.
Step-by-step explanation:
She write wrongly for the values of length and height. The length of V1 should be 7ft + 4ft which is 11ft and the height is 5ft.
So the volume of V1 is :
V1 = 2ft × 11ft × 5ft
= 110 ft³

A rectangular swimming pool is 19 m wide by 35 m long. what is the length of the diagonal of the pool round to the nearest 10th
Answer:
39.8
Step-by-step explanation:
for this question, use the Pythagorean theorem which is:
a^2 + b^2 = c^3
a = 35
b = 19
c = the answer
lets solve it:
35^2 +19^2 = c^2
solve the exponents first
1225 + 361 = c^2
1586 = c^2
square root both to find c
(the answer is rounded)
39.824 = c
rounded to nearest 10th:
c = 39.8
Answer:
the answer is 39.8m
Step-by-step explanation:
You divide the pool with the diagonal and you obtain a right angled triangle with its base as 35m and its height as 19m. then using pythagoras theorem, you find the length of the hypotenuse and this is the length of the diagonal of the pool.

Answer:
The mode is 80
Step-by-step explanation:
The number which appears most often in a set of numbers
Answer:
80
Step-by-step explanation:
Out of the 7 bars, three of them hit 80, two hit 50, and the other two hit 60.
50, 50, 60, 60, 80, 80, 80
80 appears most in the data set, so it is the mode.

How many different possible sandwich combinations can you make
A)16
B)12
C)36
D)18
Step-by-step explanation:
Assuming we use only one kind of bread, meat and cheese, we have 3, 2, and 3 options for them respectively. Therefore, the total amount of sandwiches we can make is 3 * 2 * 3 = 18.

Solve system of equations for x + y: -4x + 9y = -11 & -3x + 7y =-9
Answer:
x = -3 and y = -4
x + y = -3-4 = -7
Step-by-step explanation:
-4x + 9y = -11 ------------------------------------------------------------------------(1)
-3x + 7y = -9--------------------------------------------------------------------------(2)
multiply through equation (1) by 3 and multiply through equation(2) by 4
-12x + 27y = -33 -----------------------------------------------------------------------(3)
-12x + 28y = -36 ----------------------------------------------------------------------(4)
subtract equation (1) from equation (2)
y = -3
substitute y = -3 into equation (2)
-3x + 7(-3) = -9
-3x -21 = -9
add 21 to both-side of the equation
-3x -21 + 21 = -9 + 21
-3x = 12
divide both-side of the equation by -3
-3x/-3 = 12/-3
x = -4
x = -3 and y = -4

3*$9.99=$29.97
5*$1.29=$6.45
3 albums would cost $29.97, and 5 individual songs would cost $6.45.
3 albums would cost $29.97, and 5 individual songs would cost $6.45.
For your birthday you get an i‐Tunes gift card. The total cost for you to buy 3 albums at $9.99 each and then 5 individual songs each worth $1.29 is given by the expression 3(9.99) + 5(1.29).
What is Equation?
Two expressions with an equal sign is called as equation.
Through given data we construct equations,
3 albums at $9.99 is given by
3*$9.99=$29.97
5 individual songs each worth $1.29
5*$1.29=$6.45
Total cost for you to buy 3 albums at $9.99 each and then 5 individual songs each worth $1.29 is given by the expression.
3(9.99) + 5(1.29).
=29.97+6.45

Answer:
28
Step-by-step explanation:
Consider the expansion:
[tex]$(x+y)^2=\sum_{k=0}^{n} \binom{n}{k}y^{n-k}x^k$$[/tex]
[tex]$ \binom{n}{k}=\frac{n!}{(n-k)!k!}[/tex]
We have
[tex]$\left(x + y\right)^{8}=\sum_{k=0}^{8} \binom{8}{k} \left(y\right)^{8-k} \left(x\right)^k[/tex]
I'm sorry but I will not write and solve everything, typing LaTeX takes time. But that's the idea:
For [tex]k=0[/tex]
[tex]$\binom{8}{0} \left(y\right)^{8-0} \left(x\right)^{0}=\frac{8!}{(8-0)! 0!}\left(y\right)^{8} \left(x\right)^{0}=y^{8}[/tex]
For [tex]k=2[/tex]
[tex]$\binom{8}{2} \left(y\right)^{8-2} \left(x\right)^{2}=\frac{8!}{(8-2)! 2!}\left(y\right)^{6} \left(x\right)^{2}=28 x^{2} y^{6}[/tex]
[tex](x+y)^8={x}^{8} + 8{x}^{7}y + 28{x}^{6}{y}^{2} + 56{x}^{5}{y}^{3} + 70{x}^{4}{y}^{4} + 56{x}^{3}{y}^{5} + 28{x}^{2}{y}^{6} + 8x{y}^{7} + {y}^{8}[/tex]
Rectangle LMNO has vertices L (–4, 6), M (–1, 6), N (–1, 2), and O (–4, 2). Suppose you reflect this rectangle across the x-axis, and then translate it up two units. What are the corresponding vertices of L′′M′′ N′′O′′? Question 11 options: A) L′′ (–4, –4), M′′ (–1, –4), N′′ (–1, 0), O′′ (–4, 0) B) L′′ (4, –4), M′′ (1, –4), N′′ (1, 0), O′′ (4, 0) C) L′′ (–4, 8), M′′ (–1, 8), N′′ (–1, 4), O′′ (–4, 4) D) L′′ (–4, –8), M′′ (–1, –8), N′′ (–1, –4), O′′ (–4, –4)
Answer:
The correct option is:
A) L'' (-4 , -4) , M'' (-1 , -4) , N'' ( -1 , 0) , O'' (-4 , 0)
Step-by-step explanation:
The following are the vertices of a rectangle LMNO
L (-4 , 6)
M (-1 , 6)
N (-1 , 2)
O (-4 , 2)
First we have to reflect it across x-axis
When we reflect a shape across x-axis, the x components of the points remain the same while y components change their signs. After reflection:
L' (-4 , -6)
M' (-1 , -6)
N' ( -1 , -2)
O' (-4 , -2)
After we translate it up by two units, we add +2 to y components of each reflected point.
L'' (-4 , -4)
M'' (-1 , -4)
N'' ( -1 , 0)
O'' (-4 , 0)
Hence, the correct option is A

Answer:
y = 2/3x
Step-by-step explanation:
The first step is to find the slope
Pick two points on the line (0,0) and (3,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(3-0)
= 2/3
The y intercept is 0
Using the slope intercept form
y =mx+b where m is the slope and b is the y intercept
y = 2/3 x +0
y = 2/3x

1/3x
