Create a question with this scenario you could ask that could be answered only by graphing or using logarithm.

Vesnalui [34]

Answer:

After how many years is the fish population 100?

x=3.97 years

Step-by-step explanation:

The fish population increases by a factor of 1.5 each year. We have the equation that represents this situation

$f (x) = 20 (1.5) ^ x$

Where x represents the number of years elapsed f(x) represents the amount of fish.

Given this situation, the following question could be posed

After how many years is the fish population 100?

So we do $f (x) = 100$ and solve for the variable x

$100 = 20 (1.5) ^ x\\\\\frac{100}{20} = (1.5)^x\\\\ 5= (1.5)^x\\\\log_{1.5}(5) = log_{1.5}(1.5)^x\\\\log_{1.5}(5) = x\\\\x =log_{1.5}(5)\\\\x=3.97\ years$

Observe the solution in the attached graph

If 2 pounds of strawberries cost $4.50 how much would 3 pounds cost?

AfilCa [17]

we know that

$2$ pounds of strawberries cost $\$4.50$

by proportion

<u>Find the cost of $3$ pounds of strawberries</u>

$\frac{4.50}{2} \frac{\$}{pounds} =\frac{x}{3} \frac{\$}{pounds}\\ \\x=(4.50*3)/2\\ \\x=\$6.75$

therefore

<u>the answer is</u>

$\$6.75$

Find the value of x and y for the equation x+y5 7x+9y=6

Nastasia [14]

Answer:

$x = \frac{39}{2}$

$y = -\frac{29}{2}$

Step-by-step explanation:

Given

$x + y= 5$ --- (1)

$7x + 9y = 6$ ---- (2)

Required

Find x and y

Make x the subject in (1)

$x + y= 5$

$x = 5 - y$

Substitute 5- y for x in (2)

$7x + 9y = 6$

$7(5 - y) + 9y = 6$

Open bracket

$35 -7 y + 9y = 6$

Collect like terms

$-7y + 9y = 6 - 35$

$2y = -29$

Divide both sides by 2

$y = -\frac{29}{2}$

Substitute this for y in $x = 5 - y$

$x = 5 - (-\frac{29}{2})$

$x = 5 +\frac{29}{2}$

L.C.M

$x =\frac{10+29}{2}$

$x = \frac{39}{2}$
