It represents simulations
We know that time is distance over velocity, that is:
time = distance / velocity
t = d / v
Now from the given:
d / 460 + d / 500 = 4.8
Now we can find for d:
d = 4.8 / [1/460 + 1/500]
d = 1150 miles
So the time of each flight is:
flight = 1150 / 460 = 2.5 hours
<span>return flight = 1150 / 500 = 2.3 hours</span>
Answer:
what type? if right then
7^2+16^2=23^2
49+256=529
305≠529
so its not a right triangle
Step-by-step explanation:
The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.
The sum of two numbers
x + y = 21
x = smaller number
y = larger number
Larger Number = y = (2x -6)
Substitute (2x - 6) for y
x + y = 21
x + (2x - 6) = 21
3x - 6 = 21
3x = 21 + 6
3x = 27
3x / 3 = 27 / 3
x = 9
Smaller number = x = 9
Find the larger number by inserting 9 into (2x - 6)
(2x - 6)
(2(9) - 6)
18 - 6
12
So
x = 9
y =12
Check our answer by inserting x = 9 and y = 12 into x + y = 21
x + y =21
9 + 12 = 21
21 = 21
So since we have 21 = 21 we know our answer is correct.
