Answer:

$\large\boxed{x=-\dfrac{7}{5}=-1.4}$

Step-by-step explanation:

$\dfrac{1}{3}(5x+1)=-2\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{1}{3\!\!\!\!\diagup_1}(5x+1)=(3)(-2)\\\\5x+1=-6\qquad\text{subtract 1 from both sides}\\\\5x+1-1=-6-1\\\\5x=-7\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}=\dfrac{-7}{5}\\\\x=-\dfrac{7}{5}$

$991.19.

<u><em>Explanation</em></u><span><u><em>: </em></u>
His starting balance is 1234.56.

<u>Subtracting the check for plumbing supplies, we have: </u>
1234.56 - 115.12 = 1119.44.

<u>Subtracting the check for his loan payment, we have: </u>
1119.44 - 225.00 = 894.44.

What change(s) should Sylvia make to the equation to find the value of t in the above scenario?

finlep [7]

Answer:

Option (D).

Step-by-step explanation:

Initial population of the deer $P_{0}$ = 4800

Decrease in the population of the deer after every 8 years = $\frac{1}{2}\times (\text{Initial population})$

Decrease in population is an exponential process, so the expression representing population will be,

$P_{t}=P_{0}(1-r)^x$

Where $P_{t}$ is the population after 'x' slots of 8 years.

r = fraction of decrease in the population

x = $\frac{\text{Number of years}}{8}$

By substituting the values of r and x in the expression,

$P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}$

$P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}$

Therefore, Sylvia should do few corrections in her expression.

(8) should be replaced by ( $\frac{1}{2}$ ) and $\frac{t}{2}$ should be replaced by $\frac{t}{8}$ .

Option D. will be the answer.
