Answer:

-3+15i

Step-by-step explanation:

Apply complex arithmetic rule: \left(a+bi\right)\left(c+di\right)=\left(ac-bd\right)+\left(ad+bc\right)i

\left(-3\cdot \:3-3\left(-2\right)\right)+\left(-3\left(-2\right)+3\cdot \:3\right)i

-3 * 3 -3 (-2) = -3

D is the midpoint of RJ⎯⎯⎯⎯. R has coordinates (−4,7), and D has coordinates (2,−1). Identify the coordinates of J.
Aleksandr [31]

Answer:

(8,-9)

Step-by-step explanation:

If the x-coordinate of R is 6 units away from D's x-coordinate, then so will J's x-coordinate. If the y-coordinate of R is 8 units away from D's y-coordinate, then so will J's y-coordinate.

Side note/Extra information:

The line would be y=\frac{-4}{3} x+\frac{5}{3}

Connor lives forty-two miles from work. This
lozanna [386]

Answer:

66 mph or 88 mph (I'm a little stuck)

Step-by-step explanation:

Here's how I got this answer:

Conner has to travel 42 miles to get to work.

He left at 7:13 and needs to get to work before 9:30.

If he's going 11 mph for 22 miles, a little less than 2 hours have passed.

If we round up to 2 hours, he has about 15 minutes to get to work.

I multiplied by 22 (the amount of miles he still has left to go) by 2 and got 44. I then realized that would take about 30 minutes (too much time). I did the same thing again but instead I multiplied by 3 and got 66. This is where I got confused. I still can't decide whether the answer is 66 mph, or 88 mph.

(I got the 88 by multiplying 22 by 4.)

(Also, I typed about the same thing in the comments but then typed it out here, too. I would wait for someone else to answer the question or you could choose between the two of my answers and hope for the best haha. You could also email you teacher or someone that could help you!)
