Answer:

Step-by-step explanation:

Given the 2 equations

y = 2x + 3 → (1)

y = - $\frac{1}{2}$ x - 2 → (2)

Since both equations express y in terms of x, equate the right sides

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

Multiply through by 2 to clear the fraction

4x + 6 = - x - 4 ( add x to both sides )

5x + 6 = - 4 ( subtract 6 from both sides )

5x = - 10 ( divide both sides by 5 )

x = - 2

Substitute x = - 2 into (1) for corresponding value of y

y = 2(- 2) + 3 = - 4 + 3 = - 1

Solution is (- 2, - 1 ) → D

A forest has 800800800 pine trees, but a disease is introduced that kills \dfrac{1}{4} 4 1 start fraction, 1, divided by, 4, e

This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.

Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,

$P( t ) = a( b )^t$ - where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )

Thus, the function $P( t ) = 800( \frac{3}{4} )^t$ can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
