Answer:
-50
Step-by-step explanation:
-12 + (-38) can also be written as -12-38, and that would be -50
Answer:
$630.80
Step-by-step explanation:
To find the new value, find the percentage being charged. 1-.24 = .76
Multiply .76 * $830 = $630.80

We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.

Answer:
f^-1 (x) = 1/2x -5/2
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 2x+5
Exchange x and y
x = 2y+5
Solve for y
Subtract 5 from each
x-5 = 2y+5-5
x-5 = 2y
Divide by 2
(x-5)/2 = 2y/2
1/2x - 5/2 = y
f^-1 (x) = 1/2x -5/2
