Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286
And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
Answer:
y = -7x - 5
Step-by-step explanation:
14x + 2y = -10
2y = -14x - 10
2y/2 = -14x/2 - 10/2
y = -7x - 5

Find the time it will take:
195 miles / 50 miles per hour = 3.9 hours.
1 hour = 60 minutes:
0.9 hours x 60 = 54 minutes.
3.9 hours = 3 hours and 54 minutes.
Add 3 hours and 54 minutes to the time it leaves:
3:30 pm + 3 hours = 6:30 PM
6:30 + 54 minutes = 7:24 PM
The answer would be 26 due to the fact that it’s just nearly above the 25 mark
Answer:
Squaring both the sides, we get a quadratic and solving it, we find that the possible values of x are -7 and -4.
Step-by-step explanation:
The expression can be written as √(x+8) - 6 = x. Take 6 on the other side and square both the sides.
[√(x + 8)]² = (x + 6)²
x + 8 = x² + 12x + 36
x² + 11x + 28 = 0
x² + 7x + 4x + 28 = 0
(x + 7)(x + 4) = 0
x = -7 and x = -4
The possible values of x are -7 and -4.
