What is the relationship between sin(90°) and sin(-90°)
sin(90°) < sin(-90°)
sin(90°) > sin(-90°)
O sin(90°) = sin(-90°)
O cannot be determined

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

just a girl thing, i think im cute when im not lol

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1
