Answer:
1. C
2. D
3. C
Explanation:
1. Girls = 12 plus twice the number of boys, so C. y = 12 + 2x.
2. You have to see which point has the second value being greater than the first value:
A) -1 > -2 is not true
B) 0 > 1 is not true
C) 2 > 3 is not true
D) 8 > 4 is true, so it's D
3. Add the two values and see if it's less than 5
A) -1-4 < 5 is true
B) 0 + 4 < 5 is true
C) 1 + 7 < 5 is not true, so this is the answer
D) 2 + 2 < 5 is true
5d(7-3)= 20d
20d-16d= 4d
3x2d= 6d
4d+6d= 10d
the answer you are looking for is 10d
notice the first term is -10, and the common difference is 3, so we add 3 to get the next term.

check the picture below.
f(x) = 2x
f(x) = 2x + 4 (Is translated 4 units up.)
If my multiplication is right the answer is <span>321.625</span>
