Answer:
We'll use the traditional "slope" formula, evaluating

To find f(5), plug in x = 5 to f(x).
3(5)^3 + 2 = 377
Same thing for f(3)
3(3)^3 + 2 = 83
So

Answer:
7 times
Step-by-step explanation:
Answer:
y=1/4x-2.25
Step-by-step explanation:
Add x to both sides to get y alone.
Then divide both sides by 4, dividing both the variable and constant on the right side.
To figure out the answer here, all you have to do is plug the given point into your equations and see if the result is true:
(4, 2) .... aka (x, y)
2 - 4 = 2
-2 = 2 ... this one is FALSE, as -2 doesn't equal 2, so already you can tell that the point won't be a solution, but still, check the second equation.
-3(4) - 2(2) = -8
-12 - 4 = -8
-16 = -8 .... this one is also false. (4, 2) is not a solution for this system of equations.
