Biologists use the formula = 70 4 to estimate an animal’s metabolic rate while resting, q Calories per day, to its body mass, M kilograms. Determine the approximate metabolic rate of a moose with a body mass of 548 kg. [2 marks]

Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

We will be using simultaneous equations to solve this problem.

Let's first establish the two equations we will be using.

Let x = smaller number

Let y = larger number

Equation No. 1 -

x + y = 0

Equation No. 2 -

14x + 9y = 1

To begin with, we will make ( x ) the subject in the first equation.

Equation No. 1 -

x + y = 0

x = 0 - y

x = - y

Next we will substitute the value of ( x ) from the first equation into the second equation to solve for ( y ).

Equation No. 2 -

14x + 9y = 1

14 ( - y ) + 9y = 1

- 14y + 9y = 1

- 5y = 1

y = 1 / - 5

y = - 1 / 5

Then we will substitute the value of ( y ) from the second equation into the first equation to solve for ( x ).

Equation No. 1 -

x = - y

x = - ( - 1 / 5 )

x = 1 / 5

FINAL ANSWER:

Therefore, the two numbers 1 / 5 and - 1 / 5.

Hope this helps! :)
