Answer:

$x(x-4)$

Step-by-step explanation:

Factor $x$ out of $x^2$

$x$ · $x$ $-4x$

Factor $x$ out of $-4x$

$x$ · $x$ + $x$ · $-4\\$

Factor $x$ out of $x$ · $x$ + $x$ · $-4\\$

$x(x-4)$

Answer:

$(-1,\frac{17}{6})$

$(3,\frac{3}{2})$

$(-5,\frac{25}{6})$

Step-by-step explanation:

The given equation is $2x+6y=15$

We substitute the ordered pairs to see which ones satisfies the equation.

For (-1,-8), we put x=-1 and y=-8 to get:

$2(-1)+6(-8)=^?15$

$-2+-48=^?15\\-50=^?15$

This is not true.

For $(-1,\frac{17}{6}))$ we put x=-1 and $y=\frac{17}{6}$ to get

$2(-1)+6*\frac{17}{6})=15\\ -2+17=15\\15=15$

This is true

For (3,3/2) we have 2(3)+6(3/2)=15

This implies 6+9=15

15=15

This is also True

For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15

This is also true.

Three friends start a business and decide to split the profits equally. Susan invests $6,000, John invests $4,000, and Pria inve

Inga [223]

Susan investment = $6000

John investement = $4000

Pria investment = $12000

investment proportion of Susan, John and Pria = 6:4:12= 3:2:6

Hence, Pria share in profit = (6/11)*$12000

= $ 6,545.454

M2=(y+10)° and m4=(3y-24)° what is m<2 show all of your work.

Ivan

Step-by-step explanation:

m∠2 = m∠4

y + 10 = 3y - 24

y - 3y = -24 - 10

-2y = -34

y = -34/-2

y = 17

m∠2 = y + 10

m∠2 = 17 + 10

m∠2 = 27°
