Please help, this is for 8th grade math.
Answer:
(2,-2)
Step-by-step explanation:
The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.
-3x+4 = 4x-10
-3x-4x+4-4 = 4x-4x-10-4
-7x = -14
-7x/-7 = -14/-7
x = 2
Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.
y = 4(2)-10
y = 8-10
y = -2
Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)
Brian, Josh, Chad, Jordan, Ryan, and Rachel are the 6 players in a round-robin racquetballtournament. Each player will play aset against each of the other players. List all the sets that need to be played.
there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6.
What is the combination?
In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.
There are a total of 6 players in the round-robin racquetball tournament, which means that each player will play a set against each of the other 5 players.
To determine the total number of sets that need to be played, we can use the combination formula:
nC₂ = (n*(n-1))/2
where n is the number of players.
In this case, n = 6, so:
6C₂ = (6*(6-1))/2 = 15
Hence, there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6:
Brian vs. Josh

How can i identify a slope
Answer:
Rise over Run.
Step-by-step explanation:
If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.
I'm sorry that might not make much sense I'm bad at explaining but let me know if that helps at all!!

In the xy-plane, a line segment is dilated by a scale factor of 2. The dilation is centered at a
point not on the line segment. Select from the drop-down menus to make a true statement about the line segment and its image. The like segments are choose, and the length of the image is choose the length of the original line segment
The line segments are parallel and the length of the image is perpendicular to the length of the original line segment.
Why is the line segment by a scale factor. ?The line segment is a part of the line and is bounded by the two distinct endpoints. The line segment that represents the x, y plane is dilated by a factor of 2 and this dilation is centered around the point and not a line. Hence are line segment is parallel and perpendicular to the length of the original point shown in the image.

Which of the following shows a translation of f(x) two units down?
A. f(x + 2)
B. f(x) + 2
C. f(x – 2)
D. f(x) – 2
Answer: D. f(x)-2
Step-by-step explanation:
Changes insides the parenthesis translate left and right. If it is [+] a number, then it is moving to the left. If it is [-] a number, then it is moving to the right.
Changes outside the parenthesis translate up and down. If it is [+] a number, then it is moving upward. If it is [-] a number, then it is moving downward.
----------------------------------------------------------------------------------------------------
Given
Translate f(x) 2 units downward
Solve
According to the rules, it should be -2 units outside of the parenthesis
Therefore, it should be f(x)-2
Hope this helps!! :)

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.
Answer:
d
Step-by-step explanation:
The volume of the triangular prism.
= Base area x length of the prism
The volume of the rectangular block.
= Length x width x height
The volume of the model house is 1260 cubic feet.
Option A is the correct answer.
What is a rectangle?
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Module house:
Triangular prism on top and a rectangular block.
The volume of the triangular prism.
= Base area x length of the prism
= (1/2 x 12 x 4) x 15
= 24 x 15
= 360 cubic feet
The volume of the rectangular block.
= Length x width x height
= 12 x 15 x 5
= 900 cubic feet
The volume of the block house.
= Volume of the triangular prism + Volume of the rectangular block
= 360 + 900
= 1260 cubic feet
Thus,
The volume of the model house is 1260 cubic feet.
Option A is the correct answer.
