Answer:
y = 3x -1
Step-by-step explanation:
When x goes up 2 units from 5 to 7, y goes up 6 units, from 14 to 20. That's 3 times as many units as the change in x.
When x goes up 4 units from 7 to 11, you goes up 12 units, from 30 to 32. That's 3 times as many units as the change in x.
So, the slope of the function is constant at 3. If y were 3x exactly, the output numbers would be 15, 21, 33, each of which is 1 higher than the actual output. Hence the output must be one less than 3x, or ...
y = 3x -1
Solutions
To solve the problem we first have to convert the fraction into a decimal. To convert a fraction into a decimal you have to divide the <span>numerator</span> by the denominator.
7/8
= 7 ÷ 8
= 0.875
0.875 is bigger then 0.78 therefore 7/8 is greater.
The answer would be 199/37 or 5 14/37
