Answer:

m=1/300 du

Step-by-step explanation:

we have that m=∫∫rho(x,y)dA for this we must find the limits of integration (according to the graph1)

On the x axis: if y=2x and x+2y=1 then y=2x and y=(1-x)/2 ⇒ 2x=(1-x)/2 ⇒ 4x=1-x ⇒ 5x=1 ⇒ x=1/5; on the y axis y=0 and y=1/2

m=∫∫rho(x,y)dA (view the graph 2)

What is the solution set of this inequality? 3|p + 4| + 5 < 8 (–5, –3) (–3, 0) (0, –5) (3, 5)
Viefleur [7K]

Given:

The inequality is

3|p+4|+5

To find:

The solution set for the given inequality.

Solution:

We have,

3|p+4|+5

3|p+4|

3|p+4|

Divide both sides by 3.

|p+4|

It can be written as

-1

Subtracting 4 from each side, we get

-1-4

-5

The solution set of the given inequality is (-5,-3).

Therefore, the correct option is A.
