Well, from the first row to the second you added +7 on both sides. On the other rows you merely did some arithmetic.
Usually one gets from the first line to the last one directly :)
<h3><u>y = 1/2x + 2 is the given equation in slope-intercept form.</u></h3>
3x - 6y = -12
Currently, this is in standard form.
In order to convert this to slope-intercept form, we need to isolate y.
Add 6y to both sides.
3x = -12 + 6y
Add 12 to both sides.
3x + 12 = 6y
Divide both sides by 6.
Answer:
Whoa, that's a lot to answer...
15. 30000=500x
16. y=58x+5
in 16, the total cost is y, so y has to be in 1 side for itself. and we need to add the amount of tickets and the fee (5$). So we get that equation.
Are you missing something?
2xy=7
5xy=9
does not have a solution.
If you mean
2x+y=7
5x+y=9
please say so.
