Write the point slope form of the line that passes through (-8,2) and is parallel to a line with a slope of

1 answer:

Parallel lines have the same slope, so the new line will have the same slope as does the given line (which you have not yet given us!). If the given line has slope m = 5, then

y-2 = 5(x-[-8]), or y-2 = 5(x+8).

alternatively, y = 2 + 5x + 40, or y = 5x + 42

Please go back, find the slope of the given line, and re-do this problem, reflecting the value of the given slope.

Find the general solution of (x+3)y’=2y

gregori [183]

Answer:

$y=C(x+3)^2$

Step-by-step explanation:

We are given:

$\displaystyle (x+3)y^\prime=2y$

Separation of Variables:

$\displaystyle \frac{1}{y}\frac{dy}{dx}=\frac{2}{x+3}$

So:

$\displaystyle \frac{dy}{y}=\frac{2}{x+3} \, dx$

Integrate:

$\displaystyle \int\frac{dy}{y}=\int\frac{2}{x+3}\, dx$

Integrate:

$\displaystyle \ln|y|=2\ln|x+3|+C$

Raise both sides to e:

$|y|=e^{2\ln|x+3|+C}$

Simplify:

$|y|=(e^{\ln|x+3|})^2\cdot e^C$

So:

$|y|=C|x+3|^2$

Simplify:

$y=\pm C(x+3)^2=C(x+3)^2$

What is 1/8 of a full rotation

Naya [18.7K]

Answer:

45°

Step-by-step explanation:

If we consider a full rotation to be 360°, we can simply divide 360 by 8 to find 1/8 of a full rotation.

360 ÷ 8 = 45

1/8 of a full rotation is 45°

The price of printing digital photos is $1.40 for 7 prints. If Louie wants to

Alex777 [14]

Answer:

It will cost $9.80

Step-by-step explanation:

To find the cost, you have to divide the cost for 7 prints and then multiply it by 49.

1.40÷7= 0.2

0.2×49= 9.8

The answer that you get is the total cost for 49 prints.
