Easy,
split them up,
-4(-11+4n)=
=44-16n
then
-3(-2n+9)=
=6n-27
Making it, 44-16n+6n-27, add your apples and oranges
-16n+6n=-10n
44-27=17
-10n+17.
Thus, this is your answer.

Step-by-step explanation:
<span>x2 = 81 if and only if x = 9.
</span><span>this statement means
</span>x2 = 81 implies x = 9, and x = 9 implies x²=81
so the converse of <span>If x = 9, then x2 = 81 is </span><span>If x2 = 81, then x = 9</span>
Answer:
y = 2·5^x
Step-by-step explanation:
Using the given points, we can solve for 'a' and 'b'.
y = ab^x
2 = ab^0 = a . . . . . substitute (0, 2) for (x, y)
__
1250 = 2·b^4 . . . . substitute for 'a' and (4, 1250) for (x, y)
625 = b^4 . . . . divide by 2
5 = b . . . . . . . take the 4th root
The function is ...
y = 2·5^x
____
<em>Additional comment</em>
There are two real and two imaginary 4th roots of 625. Only the positive real root is useful as the base in an exponential function like this.
