Answer:

\frac{3x}{x + 2}  +  \frac{4x}{x - 2}  \\  \frac{(3x(x - 2) + (4x(x + 2))}{(x + 2)(x - 2)}

(3x²-6x+4x²+8x)/(x²-2²)

(7x²+2x)/(x²-4)

comparing with

ax²+bx/x²+c

we get

a=7

b=2

c=-4

I require assistance once again.​
stealth61 [152]

Answer:

I can help you with 1, 2 and 3.

Step-by-step explanation:

1. 2x + 3y = 1470

Subtract 2x from both sides: 3y= -2x+1470

Divide three from both sides: y= \frac{-2}{3}x +490

2. To graph it, you would first go to (0,490) because that is where the y-intercept is. Since slope is ride over run, you can either go up 2 left3 or down 2 right 3. You can proceed doing that until you have enough points to draw the line.

3. f(x)= -2/3x +490. This function means represents how many wraps are sold based on how many rolls are sandwich.

How do you graph y=3x-4 on a coordinate grid
mars1129 [50]

Answer:

You can look at the screenshot

Step-by-step explanation:

So one point of the line is (0, -4) and another point is (4/3, 0). Plot these points on a graph and draw a line.

0, -4 is from making x = 0, and then 4/3, 0 is from making y = 0.

Find the distance between the points (4,-2) and (0,10)
vagabundo [1.1K]

We can solve this problem by using the distance formula. The distance formula is: \sqrt{(x_{1}-x)^{2} + (y_{1} - y)^{2}} We can now put in values and solve.

\sqrt{(4-0)^{2} + (-2-10)^{2}}  

\sqrt{16 + 144}

\sqrt{160}
