Answer:

Option C - 10

Step-by-step explanation:

Given : Function f(x)=5x

To find : Evaluate the function for the value x=2

Solution :

We have given the function f(x)=5x

We have to find the value of f(x) at x=2

Substitute x=2 in the given function f(x)

f(x)=5x

f(2)=5(2)

f(2)=10

Therefore, Option C is correct.

Which expressions are polynomials?
Oduvanchick [21]

Answer:


Step-by-step explanation:

Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in y^{2}), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.

1. 6 + p

Being p be a variable this equation is polynomial

2.  x – 1

Since x-1 has variable and constant so according to definition it is a polynomial

3. 8x−z3

According to definition it is a polynomial

4 .5x^{2}-x\sqrt{}

Since has root so it is not a polynomial .

Answer:

Square.

Step-by-step explanation:

given J(-4,2) || K(0,3) || L(1,-1) || M(-3,-2)

given below the visual answer.

OR

you can find the distance of coordinate to coordinate:

Distance of JK

√(-4-0)² + (2-3)²

√17

Distance of KL

√(0-1)²+(3--1)²

√17

Distance of LM

√(1--3)²+(-1--2)²

√17

Distance of MJ

√(-3--4)²+(-2-2)²

√17

All sides are similar of √17 , so its a square.
