The answer would be 3.4
Hope that helped : )
Answer:
5641 55/81
Step-by-step explanation:
you can simplify the equation by removing the parenthesis.
this means that you also have to solve the ^4 part.
this would be
5641 55/81
I know that this is a large number but that is what happens when you do ^4.
Answer:
The y= -28x+4 function is changing more quickly because the -28 of x is the bigger number meaning it is the bigger slope.
Step-by-step explanation:
hopefully that helps, if not let me know of the option you have that I can select from to fully answer the question.

You can begin to simplify this by factoring both the numerator and denominator:

Next, cancel out any common factors in both the numerator and denominator:

Your answer would be

Answer:
-5i and 5i cannot be roots of the equation, since they are complex.
Step-by-step explanation:
A 3-degree polynomial equation must have 3 roots, if one of its roots is a complex number, then its conjugate must also be a root of the function. The problem already stated two roots, which are reals, therefore the last root must also be real. Using this line of thought we know that -5i and 5i cannot be roots of the equation, since they're complex.
