Y=2/3x+3 so slope = 2/3

2x-3y=8
3y = 2x - 8
y = 2/3x - 8/3 so slope = 2/3

both equations have same slope = 2/3

so answer: parallel

Based on the ratios shown ion the double number line, what is the cost for 5 pounds of almonds? :)

denis-greek [22]

I found the answer to this by first dividing 34 by 4 to get 8.5. We already know what 4 divided by 4 is. For every one pound of almonds, it costs $8.50. Since we know that we need to find out how much it costs for 5 pounds of almonds, we simply multiply 8.5 by 5 to get 42.5. It costs $42.50 to buy 5 pounds of almonds.

2a) Solve using substitution.

Tcecarenko [31]

First things first, write out your equation without the substitution.

2x+ 2y= 10

Now, put in the substitution.

2x+ 2• 2= 10

Combine like terms.

2x+ 4= 10

Now that your equation it simplified, you need to reverse the problem and put everything on the other side.

2x+ 4= 10
- 4 - 4
2x = 6

2x=6
— —
2 2

X= 3

So the final answer is x=3
