PRECALC AB

1 answer:

3 0

Answer:

So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of 2 ounces lost per second. Now that we know the slope, we can answer the questions

A. We can get the equation by finding the y int. (below) and writing it as y=-2x+68

B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2x5=10+58= 68 ounces at the beginning.

C. Since we have the formula and the slope, we just need to find when y hits 0. and that is: After 34 seconds.

Answer:

Step-by-step explanation:

Let us say, Olivia's age is x.

Now as the question says, we will get this equation.

$( \frac{1}{3} x ) + 12= 2x - 3$

Multiply both sides by 3.

$x + 36 = 6x - 9$

Collect like terms.

$x - 6x = - 9 - 36$

Calculate.

$- 5x = - 45$

Divide both sides of the equation by -5.

$x = 9$

Then, we will get the answer.

I hope it helps.
