Step-by-step explanation:

(-2,1), (-7,2)

y ^{2}  - y ^{1}   \\ x ^{2}  - x ^{1}

y ^{2}  =  - 7

y ^{1}  = 1

x ^{2}  = 2

x^{1}  =  - 2

m =   \frac{ - 7 -( 1)}{2 - ( - 2)?}

m =  \frac{ - 8}{4?}

m =  - 2

I only know how to find the slope.

Answer:

Step-by-step explanation:

Coordinates of B is (3,-4)

You multiply -2 by 2 to get -4 and then create the equation  then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)

You multiply -1 by 2 to get -2 and then create the equation then you subtract 2 by -2 which gives you -4 (y coordinate of B)

To check your answer use the midpoint formula  

  which will give you the midpoint (-2,-1)

a carton contains soup cans weighing a total of 20 pounds. Each can weighs 1-1/4. How many cans does the carton contain?
il63 [147K]
This is a division problem.

20 divided by 1 1/4

20/(1 1/4) = 20/(5/4) = 20/1 * 4/5 = 80/5 = 16

There are 16 cans.

F(x)=15x³+22x²-15x+2<br> Write f(x) as a product of linear factors.
Goryan [66]

Answer:

(5x  - 1)(3x - 1)(x + 2)

Step-by-step explanation:

(15 {x}^{3}  + 22 {x}^{2}  - 15x + 2)

Apply Rational Root Theorem, our possible roots will be

plus or minus( 2/15, 2/5,2/3,2, 1/15,1/5,1/3,1).

I

I tried root -2 and it work so

If we apply synthetic dividon, we would be left with

15 {x}^{2}  - 8x + 1

We can factor this regularly.

Apply AC method that a number

AC will multiply to 15 but add to -8.

The answer are -5 and -3 so we write this as

15 {x}^{2}  - 5x - 3x + 1

Factor by grouping

(15x {}^{2}  - 5x) - (3x + 1)

5x(3x - 1) - 1(3x - 1)

So our factor are

(5x - 1)(3x - 1)(x + 2)
