Answer:
The third one (parabola)
Step-by-step explanation:
Do a vertical line test.
Basically draw vertical lines over the function. If the x-value has more than one y-value then it is a relation and not a function
Answer:
When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to". To CHECK an inequaltiy, it is not possible to test every value.
Step-by-step explanation:
12/X=X/6
X^2=72
X= 8.48
X=8.5
18/y=y/12
Y-^2= 216
Y= 14.69
Y= 14.7
Mean of data = sum of values ÷ number of data
We have three values; 84, 87, and
Sum of values =
=
We want the value of
to give mean between 85 and 90 inclusive
Hence, the value of
is between 84 and 99 inclusive
Answer:
C) 1
Step-by-step explanation:
Since this a linear table, there has to be a minus or plus. In this case it's +3 or -3. When starting at top, it says 10. Next is 7. The difference is -3. So after is 4. Again, -3. And finally "?" For this you -3 from 4 because it is linear and that is the pattern. The answer is 1. So C is correct
