Step-by-step explanation:
Remark
This would be easier to understand if it was written like f(x) - g(x). You might see what the question really is.
Equation
(f - g)x = f(x) - g(x)
Solution
(f - g)x = 9 - x - (3 - x) remove the brackets
(f - g)x = 9 - x - 3 + x
(f - g)x = 6
14/1 x 3/5 = 42/5 which then equals 8 1/20
The answer is "No they are not proportional" since the line y = 4x-5 doesn't go through the origin. Put another way, the equation is not in the form y = k*x for some fixed value k.
Answer: x=2
Step-by-step explanation:
To find out what x equals you have to find the rate of change. You do this by dividing 9 from 6 this will give you 1.5. Then you divide 3 by 1.5 then you get 2
Hope this helps :)
