![17](https://tex.z-dn.net/?f=17)
Step-by-step explanation:
If f(x)=4x2-x+3, then what is the value of f(2)
![f(x)=4x {}^{2} -x+3 \\ f(2) = {4(2)}^{2} - 2 + 3 \\ = 4 \times 4 + 1 \\ = 16 + 1 \\ = 17](https://tex.z-dn.net/?f=%20f%28x%29%3D4x%20%7B%7D%5E%7B2%7D%20-x%2B3%20%20%5C%5C%20f%282%29%20%3D%20%20%7B4%282%29%7D%5E%7B2%7D%20%20-%202%20%2B%203%20%5C%5C%20%20%3D%204%20%5Ctimes%204%20%2B%201%20%5C%5C%20%20%3D%2016%20%2B%201%20%5C%5C%20%20%3D%2017)
the answer is 2
there are 13 days, 6x2=12. so the answer is 2.
105/1760 = x/60
105 yards per minute over 1760 (number of yards in a mile) is equal to X (solving) over 60 (the number of minutes in an hour)
x = 3.579 = 3.58 miles per hour.
