Answer:
h(x) = 0.0045x – 0.4
Step-by-step explanation:
The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.
Flight A: f(x) = 0.003x - 1.2
Flight B: g(x) = 0.0015x + 0.8
Then the function
h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.
Therefore, the third option is the right option. (Answer)
Simplify:
-3 - (-t - 5) > 0
t + 2 > 0
t > -2
Answer:
Step-by-step explanation:
I'm assuming that the two points lie on a line and that we want the slope/intercept equation for the line
slope is change in y over change in x
s = (-7 - (-2)) / (5 - 0) = -1
y intercept is found when x = 0 which happens to be one of our point pairs.
(0, -2)
y = -1x - 2
3 5/6 + 4 1/6 =
add the whole numbers....3 + 4 = 7
add the fractions....5/6 + 1/6 = 6/6 = 1
add them together....7 + 1 = 8 hrs <===
