Which function has the given properties below?

the domain is the set of all real numbers.

one x-intercept is 6.0

the maximum value is 3.

the y-intercept is (0, -3).

y=-3sin(x)

y=-3cos(x)

y = 3sin(x)

y = 3 cos(x)

50- 250 is correct i did that one too

step-by-step explanation:

96 39 cause 135 -96=39 im smart (i used a calculater)

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
