Answer:
y = 1/7x -16/7
Step-by-step explanation:
We can point slope form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = 1/7(x-2)
y+2 = 1/7(x-2)
Distribute
y+2 = 1/7x - 2/7
Subtract 2 from each side
y+2-2 = 1/7x -2/7-2
y = 1/7x -2/7 - 14/7
y = 1/7x -16/7

Kayla works at flower store.the owner tells kayla he wants to take 10 percent off a 18.00$ bouquet. If the bouquet still doesn’t sell the owner will again reduce the sale price by 15 percent. Kayla tells the owner the original price by 25 percent because the sale price would be the same
Answers
Kayla is wrong because the calculation will give different amounts since one gave $13.77 while the other one was $13.50.
Taking 10% off and then 15% off will give a price that will be calculated thus:
= $18 - (10% × $18)
= $18 - $1.80
= $16.20
Taking 15% off will then be:
= $16.20 - (15% × $16.20)
= $16.20 - $2.43
= $13.77
Now taking 25% off directly firm $18.00 will give:
= $18.00 - (25% × $18.00)
= $18.00 - $4.50
= $13.50
Therefore, Kayla is wrong.

Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answers
Answer:
Perpendicular
slope Ab = undefined
slope Cd = 0
Step-by-step explanation:
slope AB = undefined, a vertical line has no slope
slope CD = 0 (a horizontal line has no slope)
Answer:
AB: Undefined
CD: 0
Perpendicular
Step-by-step explanation:
Slope is the change in y over the change in x
(sometimes called "rise over run")
Formula looks like this:
[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]
First let's find the slope of AB
[tex]\frac{7-3}{-5 --5 }[/tex]
[tex]\frac{7-3}{-5 +5 }[/tex]
[tex]\frac{4}{0}[/tex]
Undefined
Then the slope of CD:
[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]
[tex]\frac{9 -9}{-10 - 1 }[/tex]
[tex]\frac{0}{-11 }[/tex]
0
If they are parallel they will have the same slope, perpendicular lines have negative reciprocals as the slope, and neither is neither
Comparing the slope of our lines lead us to know that the two lines are perpendicular because AB is vertically up + down and CD is horizontally right + left
I hope this is correct and helps, have a nice day :D

A dilation is given by the transformation (x, y) →
(.75x, .75y). What type of dilation is this?
A) it is not a dilation
B) reduction
C) enlargement
Answers
Explanation:
We're multiplying each coordinate by 0.75, which is a value between 0 and 1. Whenever the scale factor is between 0 and 1, we always have a reduction. In this case, the linear dimensions are decreasing by 25% because 1-0.75 = 0.25 = 25%
So for instance, if the preimage had a side length of 12, then 0.75*12 = 9 is the corresponding image length. This is a reduction of 12-9 = 3. Then note how 3/12 = 0.25 = 25% is how much of a reduction we're dealing with.

Donald Trump wants to build a 100 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget and is willing to spend any amount to get the job done.
He has chosen to build the tower with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall. The blocks interlock on top and bottom (like legos). They cannot be stacked sideways or on their ends.
Using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are.
What is the shortest amount of time (weeks) that it will take to build the tower?
I looked up the answer, and everywhere it says that it is 10 weeks, but would it work with 1 stack of 100 blocks (1 week)?
Answers
Answer: 100 weeks
Step-by-step explanation: I think this is like a trick question or what not. I’m going to give you my best answer. It takes 1 week to stack a block and he wants it to be 100 meter tall. 1 block is one meter tall and since it takes 1 week per stack you would do 100 x 1 equals to 100 weeks. I know it says the shortest time but thats my best guess
It will take 100 weeks to build the tower.

Answers
Answer:
3
Step-by-step explanation:
There is no x in the equation, so I will assume solving for m
Distribute:
3m + 21 = 6m + 12
Subtract 3m and 12
3m = 9
Divide by 3
m = 3
Distribute 3 to (m+7) and distribute 6 to (m+2)
With that you end up with:
3m + 21 = 6m + 12
Subtract 3m from 6m
21=3m+12
Then subtract 12 from 21
9=3m
Divide by 3 in both sides
3=m

Name the values of A, B, and C when y=900+300x is written in standard form
Answers
Answer:
300x - y = -900
Step-by-step explanation:
The values of A, B, and C are 300, -1, and -900 respectively when the standard form of the equation is 300x - y = -900.
What is a standard form of an equation?An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The formula for a one-variable linear equation is written as Ax + BY = C, where a and b are constants and x is the variable.
Given equation is y = 900 + 300x, the standard form of the equation can be written as:-
Ax + Bx = C
y = 900 + 300x
Convert the above equation into standard form.
-300x + y = 900
Compare the equation to get A, B, and C.
A = -300
B = 1
C = 900
Therefore, the values of A, B, and C are 300, -1, and -900 respectively when the standard form of the equation is 300x - y = -900.
