Answer:

-2(x -2y)(x +y)

Step-by-step explanation:

Given:

(x- 2y)^2 -3x(x - 2y)

Find:

the factored form

Solution:

We notice that (x -2y) is a factor of both terms, so we can factor it out:

= (x -2y)(x -2y -3x) = (x -2y)(-2x -2y)

= -2(x -2y)(x +y)

What is the slope between the points (3,-4)&(7,6)?

olchik [2.2K]

Answer: The slope is $\frac{5}{2}$

Step-by-step explanation:

1. You need to apply the following formula for calculate the slope:

$m=\frac{y_{2}-y_1}{x_{2}-x_1}$

2. Given the points, (3,-4) and (7,6), you have:

$y_{2}=6\\y_1=-4\\x_{2}=7\\x_{1}=3$

3. Substitute these values into the formula for calculate the slope, as following:

$m=\frac{6-(-4)}{7-3}\\m=\frac{10}{4}$

4. Simplify the result. Therefore, you obtain that the slope is:

$m=\frac{5}{2}$

In the equation 0.5x - 8 = 1.5 the decimal coefficient is what

geniusboy [140]

We know that coefficient of an equation is the number multiplied by variable.

-8 and 1.5 are the constants for our given equation.

The variable of our given equation is x. We can also see that x is being multiplied by 0.5, therefore, 0.5 would be the decimal coefficient of our given equation.

Suzie paid a total of $324 dollar sign, 324 for x tickets to a rock festival.

MA_775_DIABLO [31]

Find the ticket unit cost: divide the total paid, $324, by the number of tickets, x. Then the form of the unit cost is

$324

--------- .

This question is highly unusual in that you write "x" as the number of tickets sold, instead of a specific number of tickets. Supposing that you'd sold 100 tickets for $324, then the unit cost would be, much more typically, a numeric ratio:

$324

----------------- = $3.24/ticket

100 tickets

How do I solve a question like this? (-4)5-(-6)(-4)+40

ra1l [238]

Answer:

-4

Step-by-step explanation:

We are given the following expression which we are to solve:

$( - 4 ) 5 - ( - 6 ) ( - 4 ) + 4 0$

Since this expression includes brackets as well has plus and minus signs, so we will follow the standard order of operations to solve this expression.

Solving the brackets first to get:

$( - 2 0 ) - ( 2 4 ) + 4 0$

Now adding all the terms up to get:

-4
