(Please help)Choose the correct answer and please explanation each (Brainliest) 1.let x be the number of boys and y, the number of girls in a camp. the number of girls exceeds twice the number of boys by 12. This relation is given by which of the following equation?
A. x=2y+12
B. y=12–2x
C. y=12+2x
D. y=2(12–x)
2.Which of the following ordered pairs is a point in the region described by the inequality y>x?
A. (-1, -2)
B. (1,0)
C. (3,2)
D. (4,8)
3.Which of the following ordered pairs does NOT satisfy the inequality x+y<5?
A. (-1,-4)
B. (0,4)
C. (1,7)
D. (2,2)

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

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
