The functions have complex roots from the image are
Functions (b) and (d). This is further explained below.
<h3>What is Function?</h3>
Generally, Function is simply defined as a connection between two or more variables that may be expressed mathematically.
In conclusion, Functions with graphs that never touch or cross the x-axis are said to have complicated roots, not real ones.

Answer:
Not sure if I correctly did it but Stan is 56$ and Kyle is 44$, unless they meant how much they spent and were left with.
Step-by-step explanation:
50 + 6 = 56
34 + 10 = 44
Answer:
7 hours
Step-by-step explanation:
715 / 13 = 55 miles per hour
385 / 55 = 7 hours
Best of Luck!
At 4 months the amount spent is equal at 1,600.
600+250x
400x
250*4=1000+600=1600
400*4=1600
Responder:
<em>a) 1
</em>
<em>b) 12
</em>
<em>c) 3
</em>
<em>d) -1 y 3
</em>
Explicación paso a paso:
Dadas las siguientes ecuaciones;
a) x²-x =0
x² = 0+x
x² = x
x = 1
b) -x²+12x = 0
-x² = -12x
x² = 12x
x = 12
c) 3x² - 9x = 0
Suma 9x a ambos lados
3x²-9x+9x = 0+9x
3x² = 9x
3x = 9
x = 9/3
x = 3
d) x²-2x-3 = 0
x²-3x+x-3 = 0
x(x-3)+1(x-3) = 0
(x+1)(x-3) = 0
x+1 = 0 y x-3 = 0
x = -1 y 3
