<h3>Answer: A) 5 - 3i</h3>

===========================================

Work Shown:

5 - \sqrt{-9}\\\\5 - \sqrt{-1*9}\\\\5 - \sqrt{-1}*\sqrt{9}\\\\5 - i*3\\\\5 - 3i\\\\

In step 3, I used the rule \sqrt{x*y} = \sqrt{x}*\sqrt{y}

Afterward, we use the definition that i = \sqrt{-1}

Question 8 options:
prisoha [69]

Answer:

Step-by-step explanation:

Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.  

c first:

\frac{c-8}{8-0}=34 and

\frac{c-8}{8}=34 and

c - 8 = 272 s0

c = 280

For a:

\frac{5-8}{a-0}=34 and

\frac{-3}{a}=34 and

-34a = 3 so

a=-\frac{3}{34}

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.

Help! if theres a answer already dont be discouraged as usually i still give thanks and stars will give brainliest
Strike441 [17]

7 + (4^2 + 5) x 2 = 51

(2 + 3) x 3^2 + 39 / 3 = 54

2 x [(4 + 3) x 5 - 6] = 58

[84 / (3 + 4)] x 3 + 1 = 37

Therefore none of them equal 52!
