800*2/5=320 novels
800-320=480 non fiction books
320*3/8=120 novels sold
120*7=$840
480*2/5=192 non fiction books sold
192*5=$960
$960+$840=$1800
The owner would make $1800
Answer:
7/12
Step-by-step explanation:
1/3 x4/4 = 4/12
1/4 x 3/3 = 3/12
4/12 + 3/12 = 7/12 = 5.83
Find the slope
(y2-y1)/(x2-x1)
(-13-3)/(9+3)
-16/9 = -1.333 repeating slope
Equation: y = 1.333x - 1
Since 4i is a root, that automatically means -4i is also a root (complex roots always travel in pairs)
So the factored form would look like
<span>(x+4i)(x−4i).</span>
When multiplied out this gives the polynomial
<span><span>x2</span>+<span>16.</span></span>
