State whether the given equation or function is linear. Write yes or no. Explain your reasoning. f(x) = 7x2 + 4
vagabundo [1.1K]

For this case we have the following function:

f (x) = 7x ^ 2 + 4

By definition, we have that a linear equation is of the form y = mx + b

On the other hand, a quadratic equation is of the formy = ax ^ 2 + bx + c

Then, the given equation is not a linear equation, it is not of the form y = mx + b

Answer:

No, the equation is not linear. It is not of the form f (x) = mx + b.

What numbers can give me 8 when added and 30 when multiplied
Paul [167]
In this problem, it is important to take note that the number of numbers to be utilized isn't specified so it can be up to a thousand numbers. It wasn't also specified if repeating of numbers is allowed or not. So with those taken into consideration and the condition presented in mind, the numbers that can give you 8 when added and 30 when multiplied are 2, 3, 5, -1, and another -1. The derivation from this is mainly from factorization and a little bit of logic.

here is the solution.

2 x 3 x 5 x -1 x -1 = 30
6 x 5 x -1 x -1 = 30
30 x -1 x -1 = 30
-30 x -1 = 30
30 = 30

2 + 3 + 5 + -1 + -1 = 8
5 + 5 + -1 + -1 = 8
10 + -1 + -1 = 8
9 + -1 = 8
8 = 8
