If h(x) = x - 7 and g(x) = x^2, which expression is equivalent to (gºh) (5)?
(5 – 77)²
(5)^2 -7
(5)^2(5 – 7)
(5 – 7)x²

 a) (5 - 7)²

Step-by-step explanation:

g(x) = x^2          h(x) = x - 7

                         h(5) = 5 - 7

g(h(5)) = g(5 - 7)  = (5 - 7)²         Replace the x in g(x) with (5 - 7)

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
