Answer:
-5.44
Step-by-step explanation:
multiply add negative sign
The average temperature increased from day 5 through day 7.
answer choice b is the correct answer.
if you look at the chart you see how the temp. increases throughout said days. :)
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>
D
uses the the formula y=mx+b and m is the slope. b is the y intercept.
I manually graphed the equation
