What are the solutions to the equation x - 7/x = 6

bearhunter [10]

The answer is C that is X=7 and X=-1

multiple x through the given equation to get rid of a fraction. It will be

${x}^{2} - 7 = 6x$

After that bring 6X to the LHS of the equation

so that it will look like the general equation that is

${x}^{2} - 6x - 7 = 0$

Use the quadratic formula (or any other approach to find the values of x

You will arrive at

$x = 7. - 1$

Which of the sets of ordered pairs represents a function?

IgorC [24]

Answer:

Neither set A nor set B represents a function.

Step-by-step explanation:

According to the definition of a function, for each input there exists a unique output. In other word for each value of x there exists unique value of y.

In set A we have four ordered pair (-4,5),(1,-1),(2,-2) and (2,3).

It means for x=2, we have two values of y, i.e., -2 and 3.

Since for a single value of x there exist more than one value of y, therefore set A is not a function.

In set B we have four ordered pair (2,2),(3,-2),(9,3) and (9,-3).

It means for x=9, we have two values of y, i.e., -3 and 3.

Since for a single value of x there exist more than one value of y, therefore set B is not a function.

Which is true regarding the graphed function f(x)?

Sladkaya [172]

<h2>Explanation:</h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

$f(x)=\left(x-4\right)^{2}+5$

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

$V(4,5)$

The graph of this function is shown below. Which is true regarding the graphed function f(x)?

It is true that the domain is the set of all real numbers because this is a polynomial function.

It is true that the range is the set of all real numbers such that y ≥ 5

It is true that this parabola opens upward

It is true that it doesn't cut the x-axis
