I believe it's 7.5 but I could be wrong.
Answer:
<em>10x + 50 =1 +5</em>
<em>10x=6-50</em>
<em>10x=-44</em>
<em>x=-4.4</em>
Step-by-step explanation:
Answer:
The constant of proportionality is basically just the slope, so the answer is 1/6.
Step-by-step explanation:
Count how many Y units it goes up to get the the black point from (0,0) (the origin). You go up 1 unit to go 6 units to the right meaning the slope is 1/6.
That is the rise over run technique and there are many others, such as point slope form, and y2-y1 over x2-x1.
Hope this helps!
1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price
I hope this helps you
1)
x= -2y
2. (-2y)+4y=0
0=0
2)
x+2x= -3
x=-1
y= -2
3)
7x+2x+2=4
9x=2
x=2/9
y=2/9+1
y=11/9
