Is (4, -2) the solution of the system of equations shown

Mathematics

Advocard [28]3 years ago

No, because if you substitute (4, -2) into x and y in each equation, they are not the same as the value on the right side of the equation.

2(4) + 4(-2) = - 2

8 + -8 = -2

0 = -2 <---- this is not correct.

-4(4) + -2 = -14

-16 + -2 = -14

-18 = -14 <----- this is not correct.

The table below shows the relationship between the number of calories burned and the minutes of exercise.
sergejj [24]

Answer:

Option B

Step-by-step explanation:

Since, number of calories 'C' burned is proportional to the number of minutes (m) given to the exercise,

C ∝ m

C = km

Where k is the proportionality constant.

From the table attached,

For C = 250 calories and m = 30 minutes,

250 = 30k

k = \frac{250}{30}

  = \frac{25}{3}

Therefore, equation representing this situation will be,

C = \frac{25}{3}m

Option B will be the correct option.
