Answer: My bad if I butchered any answers. It was hard to read tbh

Step-by-step explanation:

D.) You can only factor out an x here. So you'd get: x(x^2-2x+4)

E.) You can factor out a 3x^2y to get: 3x^2y(2-x)

F.) You can factor out a 3xy to get: 3xy(y+3x-2)

G.) You can factor out a -4ab to get: -4ab(a-4b+2)

I need help help pls
djyliett [7]

Answer:

MAD = 2

Step-by-step explanation:

<u><em>First We'll find the mean of data</em></u>

Mean = \frac{20}{5}

Mean = 4

<u><em>Then, we'll find absolute deviation</em></u>

=> |4-3| = 1

=> |4-2| = 2

=> |4-1| = 3

=> |4-1| = 3

=> |4-3| = 1

<em><u>Now, taking the mean of these absolute deviations:</u></em>

MAD = \frac{1+3+3+2+1}{5}

MAD = \frac{10}{5}

MAD = 2

Solve the following system of equations: x - 2y = 14 x + 3y = 9
Margarita [4]
Solve your system of equations step by step.

x−2y=14;x+3y=9

Solve x−2y=14 for x:

x−2y+2y=14+2y (Add 2y to both sides)

x=2y+14

Substitute (2y+14) for x in x+3y=9:

x+3y=9

2y+14+3y=9

5y+14=9(Simplify both sides of the equation)

5y+14+−14=9+−14 (Add -14 to both sides)

5y=−5

5y5=−55 (Divide both sides by 5)

y=−1

Substitute (−1) for y in x=2y+14:

x=2y+14

x=(2)(−1)+14

x=12(Simplify both sides of the equation)



So,

y=-1
x=12

Answer is C)
