Answer:

B. 2(5a + 3)

Step-by-step explanation:

Using the distributive property, we know that we can distribute to polynomial within parenthesis. So, following this, we can multiple 2*5a and 2*3. This gives us the expression, 10a+6. Showing that these two expressions are equivalent.

Additionally, the expression 2(5a+3) is an example of factoring. The GCF, 2, was factored out of the original expression 10a+6. Since 2(5a+3) is a factored form of 10a+6, they must be equivalent.

Answer:

A solution curve pass through the point (0,4) when $c_{1} = -\frac{4}{3}$ .

There is not a solution curve passing through the point(0,1).

Step-by-step explanation:

We have the following solution:

$P(t) = \frac{c_{1}e^{t}}{1 + c_{1}e^{t}}$

Does any solution curve pass through the point (0, 4)?

We have to see if P = 4 when t = 0.

$P(t) = \frac{c_{1}e^{t}}{1 + c_{1}e^{t}}$

$4 = \frac{c_{1}}{1 + c_{1}}$

$4 + 4c_{1} = c_{1}$

$c_{1} = -\frac{4}{3}$

A solution curve pass through the point (0,4) when $c_{1} = -\frac{4}{3}$ .

Through the point (0, 1)?

Same thing as above

$P(t) = \frac{c_{1}e^{t}}{1 + c_{1}e^{t}}$

$1 = \frac{c_{1}}{1 + c_{1}}$

$1 + c_{1} = c_{1}$

$0c_{1} = 1$

No solution.

So there is not a solution curve passing through the point(0,1).

Alexandra [31]

Answer:

$5.4 Million

Step-by-step explanation:

3.2 mill/x = 60/100

3.2 mill x 100 = 60x

320 mill = 60x

x = 5.3333 million, rounded up to 5.4 million

While traveling to and from a certain destination, you realized increasing your speed by 40 mph saved 4 hours on your return. Th

Sholpan [36]

<u>Answer:</u>

An equation that relates the speeds of the two legs of the trip

$\frac{640}{x-40}+\frac{640}{x}=4$

<u>Explanation:</u>

Given, we have to use x to represent the speed on the second leg

Speed on first leg when increasing your speed by 40 mph will be (x-40)

Distance is given as 640 miles and time is calculated as

$\text { Time }=\frac{\text { Distance travelled }}{\text { speed }}$

According to the question, increasing speed saved four hours

Therefore, the equation that relates the speeds of the two legs of the trip will be

$\frac{640}{x-40}+\frac{640}{x}=4$
