Answer:

8x-5+2x\dfrac{x}{y} = \dfrac{8xy-5y+2x^2}{y}

Step-by-step explanation:

In this question, we need to simplify 8x-5+2x\dfrac{x}{y}

We can convert elements to fractions.

8x=\dfrac{8xy}{y},\:5=\dfrac{5y}{y}

= \dfrac{8xy}{y}-\dfrac{5y}{y}+\dfrac{2x^2}{y}

As the denominators are equal, we can combine the fractions as follows :

=\dfrac{8xy-5y+2x^2}{y}

Hence, the simplified form is : 8x-5+2x\dfrac{x}{y} = \dfrac{8xy-5y+2x^2}{y}

What is the definition of Absolute value and how do you find Absolute Value?
rusak2 [61]

Absolute Value. The absolute value of a number is its distance from zero on the number line. For example, -7 is 7 units away from zero, so its absolute value would be 7.

Find the constant rate of change for each linear function and interpret its meaning
Marina CMI [18]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.

(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{6}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{2}{4}\implies \cfrac{1}{2}

What is the equation for the line? enter your answer in the box
Igoryamba
To get the equation of the line, you need two points that belong to this line.
From the given graph, we can choose any two points: (0,-4) and (-2,0)

The general for of the linear straight line is:
y = mx + c where m is the slope and c is the y-intercept

First, we will calculate the slope using the following rule:
slope = (y2-y1) / (x2-x1)
slope (m) = (0--4) / (-2-0) = 4/-2 = -2
The equation of the line now is: y = -2x + c

Then, we will get the value of the c. To do so, we will choose any point and substitute in the equation. I will choose the point (0,-4)
y = -2x + c
-4 = -2(0) + c
c = -4

Based on the above calculations, the equation of the line is:
y = -2x - 4
