Could the table x,y pairs have been generated by a linear function x 1,2,3,4 y 3,5,7,9

Which equation has the same solution as 2x^2+16x-10=0

dmitriy555 [2]

D
Divide the whole thing by 2
2(X^2+8x-5)
X^2+8x. =5
Half of 8 is 4 sq it so you add 16
X^2+8x+16= 5+16
(X+4)^2=21

If a polynomial function f(x)has root -2 + square root 8 and 9 what must be a factor of f(x)

Rasek [7]

Answer:

$(x+2-\sqrt{9}) , (x-2+\sqrt{9}) ,(x-9)$

Step-by-step explanation:

Given that f(x) is a polynomial function.

This implies that f(x) has x terms of positive integral degrees and also rational coefficients only.

Since an irrational root is given a root of f(x), we find that its conjugate also should be a root of f(x)

i.e. If $-2+\sqrt{8}$ is a root, then $-2-\sqrt{8}$ is also a root.

(Because this only when multiplied will make coefficients rational)

So the factors of f(x) should be atleast

$(x+2-\sqrt{9}) , (x-2+\sqrt{9}) ,(x-9)$

There can be other factors also but this is compulsory

Suppose you work as a clerk at a local retail store earning $6 per hour. The amount of your weekly paycheck (before taxes are ta

Viktor [21]

Answer:

x is the independent variable and it represents the number of hours worked per week by the clerk.

Step-by-step explanation:

An independent variable refers to a variable in model that is varied or changed in order to examine its effect on another variable. The other variable is called a dependent variable.

A dependent variable is a variable in a model that changes as a result of a change in the independent variable.

From the question, x is the independent variable and its represent the number of hours worked by the clerk.

F(x) represents the amount of your weekly paycheck and it is the dependent variable that changes as the number of hours worked, x, changes.

For example, since we are given:

F(x) = 6x ............................... (1)

Where;

F(x) = = depemdent variable = Amount of weekly paycheck (before taxes are taken out)

6 = coefficient of x = Earning per hour

x = Independent variable = Number of hours worked

Assuming x = 1, we can substitute this into equation (1) and have:

F(x) = 6 * 1 = $6

But when x = 2, we have:

F(x) = 6 * 2 = $12

Therefore, the dependent variable F(x) changes from $6 weekly to $12 weekly as the independent variable x changes form 1 hour to 2 hours weekly.
