X + 3y= -1
-2x - 6y = 2

These two equations have the same solution because we can see that they are equivalent. 

One way to find out is this:-

Since x has a +1 next to it, and the other equation has a (-2) next to the x, we can multiply everything on the first equation by 2 to see if they are equivalent.

x+3y= -1
(-2)*x + 3y*-2 = -1*-2
-2x+ (-6y) = 2
-2x-6y=2

Now we know that both of these equations have the same solution.

Anestetic [448]

Answer:

y = kx

Step-by-step explanation:

In proportional relationships, the value of one variable increases as the other increases or decreases as the other decreases. It is denoted mathematically as  y ∝ x where x and y are the variables. It follows that

y = kx where k is the proportionality constant.

So in the relationship where x represents the number of adults, and y represents the number of students,

y ∝ x and y = kx

y = kx is the required equation

Solnce55 [7]

Answer:

3 chocolate bars, and 2 graham crackers

Someone forgot the marshmallows...... :P

Step-by-step explanation:

Chocolate bars = 8 pack

Graham Crackers = 12pack

To have no crackers or chocolate left over, we need to find LCM

Factors of 8:

8, 16, 24, 32, 40, 48, 56, 72....

Factors of 12:

12, 24, 36, 48, 60, 72

The smallest LCM is 24

Chocolate bars:

24/8 = 3

Graham Crackers:

24/12 = 2

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
