Select the correct answer from each drop-down menu. Factor the expression 8x3y − 8x2y − 30xy. 8x3y − 8x2y − 30xy = ( )( )

pychu [463]

Answer:

$8x^3y-8x^2y-30xy=2xy(2x+3)(2x-5)$

Step-by-step explanation:

we are given an expression as

$8x^3y-8x^2y-30xy$

Firstly, we will find factors

$(2xy)\times 4x^2-(2xy)\times 4x-(2xy)\times 15$

We can see that 2xy is common in all terms

so, we can factor out 2xy from all terms

and we get

$8x^3y-8x^2y-30xy=2xy(4x^2-4x-15)$

now, we can factor again

$4x^2-4x-15=(2x+3)(2x-5)$

we get

$8x^3y-8x^2y-30xy=2xy(2x+3)(2x-5)$

Is the equation conditional, an identity, or a contradiction? y - 11 + 3y = 6y + 4

ipn [44]

Answer:

The equation is a conditional.

y = 7.5

Step-by-step explanation:

y - 11 + 3y = 6y + 4

4y - 11 = 6y + 4

4y - 4y - 11 = 6y - 4y + 4

- 11 = 2y + 4

- 11 - 4 = 2y + 4 - 4

2y = - 15

2y ÷ 2 = - 15 ÷ 2

y = - 7.5

Solve the system by substitution.<br> y = 5x<br> y = 9x + 4

SVEN [57.7K]

Answer:

(-1, -5)

Step-by-step explanation:

$\left \{ {{y=5x} \atop {y=9x+4}} \right.$

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

And the answer is (-1, -5)
