Answer:
If f(x) = 3x, this means that any number that replaces x in the parenthesis, would replace x in the right side too.
When x = -1:
f(-1) = 3(-1) = -3
When x = 0:
f(0) = 3(0) = 0
When x = 3:
f(3) = 3(3) = 9

Answer:
D
Step-by-step explanation:
Correlation coefficient is the leading coefficient of the line of best fit. We can estimate the slope by looking at the plots. The plots are moving in a positive slope so we can remove B and C and E.
We're left with slope of 1 and 0.5
We can faintly imagine the line of slope 1. It doesn't really fit. SO it is 0.5
1) If you want to split something ina 2:5 ratio, you must break it into 2+5=7 pieces. Then, you assign 2 of these 7 pieces to one person and the 5 remaining pieces to the other, and they'll have 2/7 and 5/7 of the total. for a ratio of 2:5, as required.
So, kindonoghwa gets 2/7 of 200000000, which is approximately 57142857.14.
2) We have
Divide both sides by 4:
This is equivalent to
