Find the equation of the line passing through the points (-1,7) and
(2,-8). Write the equation in slope-intercept form.
A) y = -5x + 2
B) y = -5x + 7
C) y = 5x + 12
D) y = 5x – 18

Please help

Answers

Answer 1
A)
slop intercept form is y=mx+b

To find m, it is (y2-y1)/(x2-x1) or (-8-7)/(2-(-1)) which then = -5

To find b, the y-intercept choose one of the points and solve for b using:
y=x(slope)+b
7= -1( -5)+b
7= 5+b
2=b (subtract 5 on both sides)

I hope this helped!

Answers

Answer:

  (c)  8x -16

Step-by-step explanation:

The outside factor multiplies each of the terms inside parentheses.

  4(2x -4) = 4(2x) +4(-4) = 8x -16

_____

Additional comment

You can think of parentheses as a "bag". The factor outside tells you how many bags you have. When you dump that many bags (eliminate parentheses), you find that the number of each of the kinds of contents is the number in one bag, multiplied by the number of bags.

If you have 4 bags that each have 2 apples and 4 oranges, your total is 8 apples and 16 oranges.

Answers

Step-by-step explanation:

1a)

it means that after 14 hours into the experiment the temperature of the liquid reaches exactly the temperature of the surrounding room at that moment : 10° F.

1b)

it is the point (14, 10), and I know, because both lines touch or cross each other at that point, as due to the equality relation both curves contain this point (meaning they have the same result value 10 for the same function argument 14).

4a)

because the slope of the line segment at the end is larger (making the line go up at a much steeper angle) than fire the line segment at the beginning.

4b)

it looks like the experiment started at hour 0 with the liquid being at around -5° F.

and it reached +10° F after about 10 hours.

the x (time) difference is +10 (from 0 to 10).

the y (temperature) difference is +15 (from -5 to 10).

so, the slope at the beginning of the excitement is about +15/+10 = 3/2.

and at the end of the experiment it looks like the last line segment starts at about 20 hours with the liquid at about -3° F. and it ends at hour 30 and at 30°F.

the x (time) difference is +10 (from 20 to 30).

the y (temperature) difference is +33 (from -3 to 30).

so, the slope at the end of the excitement is about +33/+10, which is much bigger than 15/10 at the beginning.

check the picture and youll know.

Answer quick!!

Answers

A reasonable price for X would be $ 2.

Since a class of 30 students visits an art museum and a special exhibit while there, and the prices were as follows:

Child (under 5) Free Free Student $ 8 $ x Regular $ 12 $ 4 Senior $ 10 $ 3

To estimate a reasonable value for x, the following logical reasoning must be made:  

Regular 12 Senior 10 Student 8 = -2 Regular 4 Senior 3 = -1

Therefore, a reasonable price for X would be $ 2.

) Kora is working on a scrapbooking project. She buys packages of stickers at two different stores.
The price of the stickers at each store is p dollars, but each store offers a different discount
Discount on Packages of Stickers
• Which expression represents the total price Kora
pays for 5 packages of stickers at Store A and
3 packages of stickers at Store B?
3{p - 100) + 512 -0.75) 5(p+1.00 +3(p+0.75)
Store A $1.00 off each package
Store B $0.75 off each package
5(p - 1.00) + 3(p -0.75)
3(p+1.00) + 5(p +0.75)

Answers

The expression that can be used to represent the total price is 3(p - $0.75) + 5(p - $1).

The expression that can be used to determine the total amount spent in store A is:

number of stickers bought x ( price of the item - discount) number of  stickers bought = 5 price of the stickers  = p discount = $1

5(p - $1)

The expression that can be used to determine the total amount spent in store B is:

number of stickers bought x ( price of the item - discount) number of  stickers bought = 3 price of the stickers  = p discount = $0.75

3(p - $0.75)

Total price = 3(p - $0.75) + 5(p - $1)

Answer:$44.69

Step-by-step explanation:

Original cost = $45.87

Cost with sales = 45.87 x 0.10 since 10% is 0.10 as a decimal

New cost = (45.87) - (45.87 x 0.10)

=$41.283

Cost with tax  = 41.283 x 1.0825       <- 8.25% is 0.0825 as a decimal

= $44.69

Answer:

$44.69

Explanation

10 Percent of $45.87 is 4.587 rounded to the nearest hundredth is $4.59.

$45.87 - $4.59 is $41.28

8.25% of $41.28 is 3.4056 rounded to the nearest hundredth is $3.41.

$41.28 + $3.41 is $44.69
