Sketch the graph of each line.<br> 2x-5y=25
ki77a [65]
Well, you transform the standard form equation into slope-intercept form (y=mx+b), since you can only graph it using this form.

First of all, the layout of the equation is Ax+By=C

So, in this case, A is 2, B is 5, and C is 25.

Now, to put it into slope intercept form, you either use the formula to change it and solve it:

y= \frac{-A}{B}x+ \frac{C}{B} \\ y= \frac{-2}{-5}x+ \frac{25}{-5} \\  \\ y= \frac{2}{5}x-5

Or you can just solve for y:

2x-5y=25 \\ 2x-5y-2x=25-2x \\ -5y=-2x+25 \\  \frac{-5y}{-5}= \frac{-2x+25}{-5} \\  \\ y= \frac{2}{5}x-5

In addition, I attached what the graph looks like.

Hope this helps!

Nitella [24]

Answer: The greatest number of plates Lenin can prepare = 4

and there will be 3 chickens and 4 rolls in each plate.

Step-by-step explanation:

Given: Lenin is preparing dinner plates. He has 12 pieces of chicken and 16 rolls.

To make all the plates identical without any food left over, the greatest number of plates Lenin can prepare = G.C.D.(12,16)=4

The number of pieces of chicken in each plate = \dfrac{12}{4}=3

The number of pieces of rolls in each plate = \dfrac{16}{4}=4

So,  the greatest number of plates Lenin can prepare = 4

and there will be 3 chickens and 4 rolls in each plate.
