Which best describes the range of the function f(x)=2/3(6)^x after it has been reflected over the x-axis

Hey!!

The correct answer is:

D) all real numbers less than or equal to 0.

Explanation:

When you reflect a function across the x-axis, you turn every y-coordinate in the function negative.

In our original function, our y-values will all be positive.  Reflecting this across the x-axis will make all of the y-values negative; this means the range, or set of y-values, will be less than or equal to 0.

central angle of a triangle has the same measure as its intercepted arc.

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
