Substitution
y = 2x - 12
y = -x + 3
-x + 3 = 2x - 12
+ x + x
-----------------------------
3 = 3x - 12
+ 12 + 12
-----------------------
15 = 3x
------ ------
3 3
x = 5
y = 2(5) - 12
y = 10 - 12
y = -2
The final answer is (5,-2).
I'd be more than happy to help. Im a sophmore and Love math

Answer:
D. there is more variability among female students with respect to GPA
Step-by-step explanation:
The standard deviation is a measure of how spread out from the mean the values within a set are. If the standard deviation for females is much higher, that means that the variability in GPAs for female students is higher than that of male students.
Therefore, it is fair to conclude that there is more variability among female students with respect to GPA.
