I cant really show you how to graph this but i can try to explain it. you would make a 4 quadrant graph and do rise over run.
1)start by making the graph
2) on the line of the graph marked Y is where you would put -4
3) From -4, you would go up (rise) by 2 and go over to the right 1 where you end is the slop

Consider the system of equations:
vodka [1.7K]

Answer:

(x, y) = (5, 1)

Step-by-step explanation:

To <em>eliminate</em> x, you can double the second equation and subtract the first.

... 2(x +4y) -(2x -3y) = 2(9) -(7)

...11y = 11 . . . . . simplify

... y = 1 . . . . . . divide by 11

Using the second equation to find x, we have ...

... x + 4·1 = 9

... x = 5 . . . . . subtract 4

_____

<u>Check</u>

2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation

(Since we used the second equation to find x, we know it will check.)

By what percent will a fraction increase if its numerator is increased by 60% and its denominator is decreased by 20%?
Strike441 [17]
Lets just use \frac{10}{20} for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being: \frac{16}{16}. Since then new one is equal to 1, and the original is equal to \frac{1}{2}, we see that this manipulation of the fraction causes an increase of 100%.

How to do number 13?
Anarel [89]

y=40

a line is 180 degrees and the other side is 70 that means 110 =2y+x so x=30 then you fill in the x. 2y+30=110 you subtract 30 from 110 and get 80 then divide 80 by 2 and get 40
