Answer:
Where d is the distance traveled, r is the rate, and t is the time. ... It took Markus half an hour to drive home from work. ... 17. Markus lives 17 miles from work. ... What was his average speed in kilometers per hour? ... per hour, we divide by 60 to find out how many hours it took. t = 20 minutes / 60 minutes per hour. = 1/3 hours.
Step-by-step explanation:
255 is the answer because 143+86=229, 229+23 is 255
Answer:
No
Step-by-step explanation:
The square root of any negative number is not a real number.
To equal the step 2, we would have to determine that 20 was our new denominator and multiply the first fraction by 5, the second by 4 and the 2 by 20.
multiplied by sides of the equation by 20
The vertex formula:
(h, k) - vertex
We have vertex (2, 3). Therefore:
We know that the parabola passes (1, -7).
Put the coordinates of this point into the function equation
x = 1, f(x) = -7
Therefore we have:
Use 
<h3>Answer: f(x) = -10x² + 40x - 37</h3>
