someone help me with this topic pls, i cant figure this out
====================================================
Explanation:
Let's label the given points A, B and C
A = (-6, -2)B = (-4, 7)C = (3, 5)To move from B to C, we do two things in either order:
Go down 2Go right 7This motion of "down 2, right 7" is copied or mirrored when we go from A to D. This is to ensure that BC is parallel to AD.
Start at point A and go down 2 units to get to (-6, -4). Then move 7 units to the right to arrive at (1, -4) which is the location of point D. You can use a tool like GeoGebra to verify the answer is correct.

At an office supply store, Samantha bought 5 notebooks and 2 pens for $9.
Jeffrey bought 3 notebooks and 2 pens for $6. Write a system of equations to represent this situation.
Answer: Let x be the cost of one notebook and y be the cost of one pen. Then we can write the following system of equations to represent the situation:
5x + 2y = 9
3x + 2y = 6
This system represents the fact that Samantha paid $9 for 5 notebooks and 2 pens, and Jeffrey paid $6 for 3 notebooks and 2 pens.
Step-by-step explanation:
Answer: hope this helps ♡
5x + 2x = 9
3x + 2x = 6
Step-by-step explanation:
x = cost of 1 item
Samantha → 5x + 2x = $9
Jeffrey → 3x + 2x = $6
5x + 2x = 9
3x + 2x = 6
What is the slope of the line that contains the points negative 3, negative seven halves and (2, −4)?
one fourth
one tenth
negative one tenth
negative one fourth
This answer was generated by an AI and may be incorrect.
The slope of a line can be found using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
Plugging in the given points, we get:
m = (-4 - (-7/2)) / (2 - (-3)) = 3/2 / 5 = 3/10
So, the slope of the line is 3/10, which is equal to one tenth.
Therefore, the answer is "one tenth."

Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.
Step-by-step explanation:
The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:
(0.17x + 60.50) - (0.09x + 30.50)
Simplifying the expression, we get:
0.08x + 30.00
Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.

What is the value of 80-2n when n=4
A: 66
B: 72
C: 76
D: 86
Answer:
B) 72
Step-by-step explanation:
The value of 80-2n when n=4 can be found by substituting n=4 into the expression and simplifying. Therefore:
80-2n = 80 - 2(4) = 80 - 8 = 72
Therefore, the answer is B) 72.

You are looking for the price of 4 pairs of shoes after 20 days of being on sale. You have $100 and you have to find out whether you can buy these shoes.
How to solve:
After 20 days 1 pair of shoes will cost:
$40/1 x 2/5 = 16$
40-16 = 24
So 1 pair of shoes will cost $24 after 20 days.
24x4 = $96
4 pairs of shoes after 20 days cost $96. We have 100$, So we will be able to purchase it.

Q.7d) q.7 find all below.
Answer:
a) 2/7 cup
b) k = 2/7
Step-by-step explanation:
2 cups of red paint (R) require 7 cups of white paint(W)
We can write this as a proportion equation:
R = k.W
where k is the constant of proportionality
Given R =2 when W = 7 we get
2 = k . 7
k = 2/7
Constant of proportionality = 2/7
So for 1 cup of White paint we will need
R = 2/7 x 1 = 2/7 cup
There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish

A stunt person opens his parachute at a height of 505 feet above the ground. He then descends at a constant rate.
Let y represent his height above the ground in feet. Let x represent the time, in seconds, he spent descending with his parachute open. Which equation is represented by the graph?
Question 2 options:
y = 505x + 17
y = 17x + 505
y = –17x + 505
y = 17x – 505
Answer:
It's -17x + 505
Step-by-step explanation:
The linear equation is like y=mx+b
Solve it by using linear equation knowledge: because the graph is going down, or the height is descending, so the the slope must be negative.
And the choise of slope is 505, 17, -17, 17, so the one with negative: -17 slope is correct.
Answer:
17x + 505
y=MX+b
Solve it by using a linear equation, the graph is going down the slope must be negative
-17 slope is The Right answer for you.
