Step-by-step explanation:

Hello there!

A good first step is to fill the t=blanks with 2 and 4.

Then proceed as follows:

$3 |2x+4|=24\\3(2x+4)=24\\2x+4=\frac{24}{3} \\2x+4=8\\2x=8-4\\2x=4\\x=2$

And there you are! Feel free to comment with questions, and have a grwat day!

The family of functions y = ce^{-2x} + e^{-x} is solution of the equation y' + 2y = e^{-x}. Find the constant c which defines th

Rufina [12.5K]

Answer:

$c = 1190.2$

Step-by-step explanation:

We have the following solution:

$y(x) = ce^{-2x} + e^{-x}$

We want to find the value of x that satisfies the following condition:

y(3) = 3.

This means that when x = 3, y = 3. So

$y(x) = ce^{-2x} + e^{-x}$

$y(3) = ce^{-2*3} + e^{-3}$

$3 = ce^{-6} + e^{-3}$

$3 = ce^{-6} + 0.0498$

$ce^{-6} = 2.9502$

$c = \frac{2.9502}{e^{-6}}$

$c = 1190.2$

Select the correct answer.

slavikrds [6]

Answer:

the answer is B

$3( \frac{7}{5} x + 4) - 2( \frac{ 3}{2} - \frac{5}{4} x)$

$(3 \times \frac{7}{5} x) + (3 \times 4) - 2( \frac{3}{2} - \frac{5}{4} x)$

$\frac{21}{5} x + 12 - 2( \frac{3}{2} - \frac{5}{4} x)$

$\frac{21}{5} x + 12 + ( - 2 \times \frac{3}{2} ) + ( - 2 \times ( - \frac{5}{4} x))$

$\frac{21}{5} x + 12 - 3 + \frac{5}{2} x$

$\frac{21}{5}x + \frac{5}{2} x + 12 - 3$

$\frac{67}{10}x - 9$
