Answer:

x = -22/3 and y = -1

Step-by-step explanation:

First, simplify the equation 12x + 20y = -108 by dividing both sides by 4:

3x + 5y = -27

now, you can subtract the two equations:

3x + 5y = -27

- (3x - 12y = -10)

17y = -17

y = -1

plug y = -1 into the equation 3x - 12y = -10

3x - 12 *(-1) = -10

3x + 12 = -10

3x = -22

x = -22/3

Make a table of values and create a line of best fit
Anni [7]
<h2>Explanation:</h2><h2></h2>

Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:

\begin{array}{cc}x & y\\0 & 0\\1 & 2\\2 & 4\\3 & 6\\4 & 8\\5 & 10\end{array}

As you can see, x increases in steps of 1 units. So let's check the difference in y:

\bullet \ \text{From x=0 to x=1} \\ \\ \Delta y=2-0=2 \\ \\ \\ \bullet \ \text{From x=1 to x=2} \\ \\ \Delta y=4-2=2 \\ \\ \\ \bullet \ \text{From x=2 to x=3} \\ \\ \Delta y=6-4=2 \\ \\ \\ \bullet \ \text{From x=3 to x=4} \\ \\ \Delta y=8-6=2 \\ \\ \\ \bullet \ \text{From x=4 to x=5} \\ \\ \Delta y=10-8=2

So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:

y=kx \\ \\ Where: \\ \\ k \ is \ constant \ of \ proportionality \ or \ the \ slope

Then:

k=\frac{2-0}{1-0}=2

Finally, the equation of the line is:

\boxed{y=2x}

What is the solution 9s =252
raketka [301]
All you need to do is find s, and get it by itself.


So, divide 9 by 252.

252/9= 28

s= 28

I hope this helps!
