Answer:
B and C
Step-by-step explanation:
(4, 2 ) → (- 4, 2 )
(- 3, - 1 ) → (3, - 1 )
We can see from both points that the y- coordinate did not change. → B
The x- coordinate of P' is the negative of the x- coordinate of P → C
Answer:
4 sophomore girls .
Step-by-step explanation:
If a student's gender and class are to be independent when a student is selected at random, two conditions must be met:
n° boys = n° girls
n° freshmen = n° sophomore
Currently, there are 10 boys and 6 girls, thus 4 girls must join.
Currently, there are 10 freshmen and 6 sophomores, thus 4 sophomores must join.
Therefore, 4 sophomore girls must join.
Y = -24x + 379
y represents money left
x represents weeks
We are finding the amount of weeks for the account to have $67 left.
Substitute y = 67
67 = -24x + 379
-312 = -24x
Divide both sides by -24 to get x by itself,
x = 13
Therefore the answer is 13 weeks!
Hope this helped!
