Answer:

B) 5 + 17i is your answer.

Step-by-step explanation:

In order to write this equation as a complex number in standard form, you must first simplify each term.

<em>Apple the distributive property.</em>

21 - 4i - 1 * 16 - (7i) + 28i

<em>Multiply -1 by 16.</em>

21 - 4i -16 - (7i) + 28i

<em>Multiply 7 by -1.</em>

21 - 4i - 16 - 7i + 28i

<em>Now simplify by adding terms :)</em>

<em>Subtract 16 from 21.</em>

5 - 4i - 7i + 28i

<em>Subtract 7i from -4i.</em>

5 - 11i + 28i

<em>Add -11i and 28i.</em>

= 5 + 17i

Jonathan's Antiques purchased an old wooden sled at an auction for $210. Jonathan wants to mark up the sled 60% of the selling p
Elis [28]
Well, if the selling price was 210, and that's the 100%, then if he adds 60% to that, the new price will be 160% of 210... well, if 210 is the 100%, what's 160% of that?

\bf \begin{array}{ccllll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;210&100\\&#10;x&160&#10;\end{array}\implies \cfrac{210}{x}=\cfrac{100}{160}

solve for "x".

I dunno how to solve this
Ksenya-84 [330]

Answer:

9

Step-by-step explanation:

First off you need to find the interval that four falls in.  

Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one.  But four is greater than three and less than ten, so it falls in the second interval.

So, now you can substitute four in for x for the second equation

4^2-7

16-7

=9
