X² - 15 x + 36 = 0
x² - 12x - 3x + 36 = 0
x( x - 12) - 3( x - 12) = 0
(x - 3)( x - 12) = 0
x - 3 = 0
x = 3
or
x - 12 = 0
x = 12
The solutions are 3 and 12
The solution would be like
this for this specific problem:
86 + 80 = 166
166 / 2 = 83
<span>So the class average is 83.
</span><span>In colloquial language, an </span>average<span> is the sum of a list of numbers divided by the
number of numbers in the list.</span>
Answer:

Step-by-step explanation:
The exponential function is
.
is the initial value of the function, or the y-value when x=0. In this case,
=5. If we enter that into the equation:

Then we can use another point to solve for
.

Since anything raised to the power of 1 remains the same, we can continue to solve algebraically.

Now that we have both the
and
value, we can return to the exponential function and fill in the blanks.

I hope this helps!
