H(x) = x + 1 k(x) = x - 2 (h + k)(2) =

barxatty [35]

$h(x) = x + 1$

$k(x) = x - 2$

_________________________________

$(h + k)(x) = h(x) + k(x)$

$(h + k)(x) = (x + 1) + (x - 2) \\$

$(h + k)(x) = x + 1 + x - 2$

$(h + k)(x) = 2x - 1$

$(h + k)(2) = 2(2) - 1$

$(h + k)(2) = 4 - 1$

$(h + k)(2) = 3$

An airplane descends 1.8 miles to an elevation of 6.75 miles. Find the elevation of the plane before its descent.

Mariana [72]

Answer: 8.55 miles

Step-by-step explanation:

Adding the totals given in the problem together:

1.8 miles + 6.75 miles = 8.55 miles.

Therefore, because we descended the plane and are looking for the previous height, we just add the descent to the elevation AFTER descent.
