What two ratios can be written for the following illustration comparing oranges to bunches of bananas? (image of 12 oranges & 4 bananas)
A. 12/4 and 1/3
B. 4/12 and 3/1
C. 3/3 and 1/1
D. 12/4 and 3/1

D

Step-by-step explanation: Because there are 12 oranges to 4 bananas. So if you simplify that you get 3 oranges to 1 banana

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

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
