Answer:

y=8/(P+q+4)

Step-by-step explanation:

we can find out that three items have y

so we can get them together Py+qy+4y=8

next(P+q+4)y=8 so y=8/(p+q+4)

Answer:

y = $\frac{8}{P+q+4}$

Step-by-step explanation:

Given

Py + qy = - 4y + 8 ← collect terms in y to the same side

Add 4y to both sides

Py + qy + 4y = 8 ← factor out y from each term on the left

y(P + q + 4) = 8 ← divide both sides by P + q + 4

y = $\frac{8}{P+q+4}$

A number minus 3 is 5. write and solve an equation to find the missing number

Mrac [35]

a number can be written a "x".

"minus" is a key word for subtraction.

"is" is a key word for =.

So if we put that all together, we have

x-3=5

To solve it, we have to add 3, to cancel it out, and add 3 to 5.

x-3=5

+3 +3

x=8

Question attached as screenshot belowPlease help me with my calculus homework I am paying close attention

Wewaii [24]

Given:

$\int ^1_{-1}\frac{1}{x^2+1}dx$

To evaluate:

As we know,

$\int ^{}_{}\frac{1}{x^2+1^{}}dx=\tan ^{-1}(x)+C$

So, we have

$\begin{gathered} \int ^1_{-1}\frac{1}{x^2+1}dx=\tan ^{-1}(1)-\tan ^{-1}(-1) \\ =\frac{\pi}{4}-(-\frac{\pi}{4}) \\ =\frac{\pi}{4}+\frac{\pi}{4} \\ =\frac{2\pi}{4} \\ =\frac{\pi}{2} \end{gathered}$

Hence, the answer is,

$\frac{\pi}{2}$
