You presented: e^(3x+6) = 8. We want to solve for (3x+6) first, and then for x.

Take the natural log (ln) of both sides. Result:

(3x+6) = ln 8

Subtr. 6 from both sides: 3x = (ln 8) - 6

(ln 8) - 6
Div. both sides by 3: x = -------------
3

Note: I highly recommend using those parentheses! ( )

A study conducted to determine the relationship between the age, x, in years of a certain brand of motorcycle and its value, y,

kirza4 [7]

Based on the equation, y = -750·x + 8500, the estimated value of a

motorcycle that is 5 years old is <u>$4,750</u>.

<h3>How can the given equation help to estimate the value of the motorcycle?</h3>

The regression equation that models the data is; y = -750·x + 8500

Where;

y = The value of the brand of motorcycle in dollars

x = The age of the motorcycle

When the motorcycle is 5 years old, we have;

x = 5

y = -750 × 5 + 8500 = 4750

Based on the equation, the estimated value of a motorcycle that is 5 years old, y =<u> $4,750</u>

bridget recieved 1400 from her grandfather as a birthday gift she decided to put the money in an account to save for college the

Simora [160]

Answer:

The amount received after 5 years is 1827.39

Step-by-step explanation:

The amount received by Bridget from his grandfather as the birthday gift = 1400 .

Since he wants to deposit it and save for college, he earns interest rate = 5.4%

He deposited this money for the years = 5 years.

Here, the Present value (PV) is = 1400

Interest rate ( r ) = 5.4% or 0.054

Since the interest rate is compounded semi annually, So, n = 10

Now if we calculate the future value of 1400 with interest rate 5.4 percent:

$\text{The amount received after 5 years} = PV(1 + \frac{r}{2} )^{n} \\$

$= 1400(1 + \frac{0.054}{2})^{10} \\$

$= 1827.39$

Therefore, 1827.39 will be the total money in his account after five years.

Solve 2x+y=10<br> 4x+7=40

WITCHER [35]

2x + y = 10 is y = -2x + 10
4x + 7 = 40
-7 -7
4x = 33
4 4
x = 8.25
y = -2(8.25) + 10
y = -6.5 and x = 8.25

Hope this helps :)
