Answer:
A. f and h
Step-by-step explanation:
For a linear function the First Differences of the y-values must be a constant. i.e. if we take the difference between any two consecutive y values or values of f(x) it should be the constant. For this rule to work, x values must change by the same number every time, which is true for all three given functions.
For function f:
The values of f(x) are: 5,8,11,14
We can see the difference in consecutive two values is a constant i.e. 3, so the First Difference is the same. Hence, function f is a linear function.
For function g:
The values of g(x) are: 8,4,16,32
We can see the difference among two consecutive values is not a constant. Since the first differences are not the same, this function is not a linear.
For function h:
The values of h(x) are: 28, 64, 100, 136
We can see the difference among two consecutive values is a constant i.e. 36. Therefore, function h is a linear function.
Answer:
5 hours
Step-by-step explanation:
227.5+97.5=325
325/65=5
If x to the 12th power is divided by x to the 9th power:
Since they share same bases, and are being divided, it would be the same as x^{12 - 9), or x^{3}
Now, simply find the cube root of 125, which is 5.
Therefore, the number (x) must be equal to 5.

Answer:
y=5x+6
Step-by-step explanation:
+6 is six more than.
5x is five times the input.
For example, let's say x=3. you gotta multiply first so you can get the five times out of the way. 3×5=15. Now we got to add six because "6 more than" means to add six. so, 15+6=21. I plugged in 21 for y to check and I got x=3, so this works.
