Answer:
3:1
Step-by-step explanation:
Take the fraction and simplify it:
12/4 = 3/1
When we give x to second, then the third will be 2x and according to informations first one should be x-6. Then you have to sum all. It ll be equal to 4x-6.
78=4x-6
84=4x
21=x
So, first number is 15, second one is 21 and the last one is 42
First we need to isolate the y in the equation
-4y=16-2x (subtract the 2x)
4y=2x-16 (divide both sides by -1)
y=1/2x-4 (divide both sides by 4)
The we know the slope of this line is 1/2. I'm not sure what the choices are, but the answer would have to have a slope of 1/2. For example, y=1/2x+2 might be an answer.
Hope this helps
