15.12 miles/ 6.3 hours= 2.4 miles/hour.
The final answer is 2.4 miles per hour~
• First way to solve:
We'll manipulate the expression of the equation:

If we have y=0:

Then, the function has one real zero (x=3) and two imaginary zeros (4i and -4i).
Answer: B
• Second way to solve:
The degree of the function is 3. So, the function has 3 complex zeros.
Since the coefficients of the function are reals, the imaginary roots are in a even number (a imaginary number and its conjugated)
The function "has only one non-repeated x-intercept", then there is only one real zero.
The number of zeros is 3 and there is 1 real zero. So, there are 2 imaginary zeros.
Answer: B.
Answer:
87509
Step-by-step explanation:
The equation is 30 x 2927 - 927 ÷ 3 + 8
You would first multiply 30 and 2927 to get 87810 - 927 ÷ 3 + 8
Then you would divide 927 by 3 to get 87810 - 309 + 8
Then you subtract 309 from 87810 to get 87501 + 8
Add
Your answer is 87509
I Hope That This Helps! :)
