well if he answers half a question per minute then it would take 2 minutes to answer a question. Therefore if you flip the numerator and the denominator you can multiply that by how many questions are being asked as shown:
q=6
1/2x2=1
2/1=2xq
2x6=12
?=12 minutes
Answer:
In a nutshell, you have to graph the parabola. Where the parabola intersects the x-axis is the solutions to the quadratic equation.
Answer:
The relation is discrete function
Domain is {x|x = 2,2,2}
Range is {y|y = 4, -1, -3}
Step-by-step explanation:
I. This function is discrete because x = 2,2,2
and y = 4, -1, -3
Or (2,4), (2,-1) and (2,-3)
If this function is continuous, the x and y will be something like this -3 <= x <= 3
II. Domain is x.value
III. Range is y.value
