<span>Z $ xy then Z = Kxy. When x = 2 and y = 3, and Z = 60, our constant of variation becomes
60 = K * 2 * 3
K = 10. Our constant of proportionality equals 10. We would need that in the second part of the equation.
When x = 4 and y = 9, we have
Z = 10 * 4 * 9 = 360</span>
Answer:
490
Step-by-step explanation:
Answer:
x > 0
Step-by-step explanation:
If is open circle it means is less than or greater than and if is closed circle it means that is less than or equal too or greater than or equal too. In this case the circle is open so it means that is less than or greater than and the only symbol available in the answer choices is greater than. So you will be stuck with the first and second option. The answer will be x > 0 because the line is going to the right meaning that x is greater than 0. Hope this helps!!
Answer:
7/17
Step-by-step explanation:
7+4+6=17
7/17
Hope this is useful :)
Step-by-step explanation:
distance = 160mile
time =5 hour or 5×60=300 minutes
speed =distance /time
v=160/300
v=0.5334miles per minute
