Use the table to answer the question. The table shows the relationship between the number of Calories Darrel burns while Kayaking and the number of minutes he leaks.
Minutes Calories Burned
50
200
100
400
150
600
200
800

4 calories

Step-by-step explanation:

From the table given, the number of calories burnt shows a proportional or linear relationship with the minutes spent while kayaking.

Calories burnt is proportional to the minutes spent.

The calories burnt in 1 minute = number of calories burnt ÷ the number of minutes spent at any given interval.

Since 200 calories are burnt in 50 mins, therefore:

Calories burnt in 1 minute =

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
