Answer:

6x^2-10x

Step-by-step explanation:

We will have to open the bracket

So let's solve the given question

2x(3x-5)

So let's start

6x^2-10x

Since any value is not given in replace of x it cannot be solved further... But in the case where a value is given,all we will have to do is to substitute and then solve further

Therefore we will have to leave our final answer to be 6x^2-10x

Whats 2 1/2 X 1 1/2 someone pls help

Answer:

15/4

Step-by-step explanation:

2 1/2 x 1 1/2

First, make them both improper fractions to make them easier to multiply

5/2 x 3/2

Multiply their numerators together to get the numerator and multiply their denominators together to get the denominator.

5 x 3 = 15

2 x 2 = 4

5/2 x 3/2 = 15/4

Find the slope of the line through the given points.(-4,7) and (-1,-3)Is the slope increasing or decreasing?

galina1969 [7]

• The following formula can be used to find the slope of a line:

$m=\frac{y_2-y_1}{x_2-x_1}$

These points are on the line:

$(x_1,y_1);(x_2,y_2)$

Given the following points:

$\mleft(-4,7\mright);(-1,-3)$

Then, you can set up that:

$\begin{gathered} y_2=-3_{} \\ y_1=7 \\ x_2=-1 \\ x_1=-4 \end{gathered}$

Therefore, substituting values into the formula and evaluating, you get:

$\begin{gathered} m=\frac{-3-7}{-1-(-4)} \\ \\ m=\frac{-10}{-1+4} \\ \\ m=-\frac{10}{3} \end{gathered}$

• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.

Therefore, the answers are:

• Slope of the line:

$m=-\frac{10}{3}$

• It is decreasing.
