<h2>Hello!</h2>

The answer is:

u+v=-1+2i

<h2>Why?</h2>

To solve the problem, we just need to consider that the variable "u" and "v" represents different expressions, and then, perform the operation and add the like terms.

We must remember that the like terms are the terms that share the same variable and the same exponent.

We have that:

u=1+3i\\v=-2-i

So, calculating we have:

u+v=(1+3i)+(-2-i)=(1-2)+(3i-i)=-1+2i

Hence, we have that:

u+v=-1+2i

Have a nice day!

Water flows down the Mississippi River at about 1.2 miles per hour
Angelina_Jolie [31]

Answer:

Continuous

Step-by-step explanation:

The rate of flow of water down the river is referred to as its speed. Thus the speed changes with respect to the distance covered. Which implies that there is a direct relationship between the distance covered (in miles) by the water flow and time taken (in hours).

The relationship between hours and miles the water traveled is continuous.

When 4(0.5x+2.5y-0.7x-1.3y+4) is simplified, what is the resulting expression?
padilas [110]

Answer:

-0.8x + 4.8y + 16

Step-by-step explanation:

4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x  + 2.5y - 1.3y + 4)

= 4( -0.2x  + 1.2y + 4)

= 4*(-0.2x)  + 4 *1.2y + 4*4

= -0.8x + 4.8y + 16
