Answer:

B.

Step-by-step explanation:

That would be B.

8/3 + √(-7/3) :-  because it consists of a real part ( the 8/3) and an imaginary part √(-7/3).

The √(-7/3) is usually written as √(7/3)i where i is √-1, so the complex number is 8/3 + √(7/3)i.

Rewrite the equation y-3=2(x+4) into slope form
soldi70 [24.7K]

Answer:

Step-by-step explanation:

So we have y-3=2(x+4)

So the first thing we want to do is distribute the 2 in front of the (x+4)

2(x+4) = 2x+8

Which means we have:

y-3=2x+8

Remember we need to get it into the form y=mx+b

As you can see here the 3 is preventing our equation from being in that form to we need to add it to both sides. This leaves us with:

y - 3 + 3 = 2x+8+3

Which gives: y = 2x+11

Therefore the slope form of this equation is y = 2x+11
