7x to the second power - x=6 find the solution set

Dahasolnce [82]

7x^2 - x = 6
7x^2 - x - 6 = 0
(7x + 6 )(x - 1) = 0
7x + 6 = 0; x = -6/7
x - 1 = 0; x = 1

answer
x = -6/7; x = 1

What is the domain of the function f(x) = + 5?

Greeley [361]

Answer:

The domain of the function is:

$\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}$

Step-by-step explanation:

Given the function

$f\left(x\right)\:=\sqrt{x+5}$

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

From the function, it is clear that for the values x<-5, the function becomes undefined.

For example, for x=-6

√x+5 = √-6+5 = √-1 which is undefined

and for x=-5

√x+5 = √5+5 = √0 which is defined

Thus, the domain of the function is:

$\mathrm{Domain\:of\:}\:\sqrt{x+5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:[-5,\:\infty \:)\end{bmatrix}$

This math is so hard. Please help!

lord [1]

Answer:

f(x)= -(x+1)^2 -2

Step-by-step explanation:

f(x)=(x-h)^2 +k; (h,k)

Then you would substitute the x and y of the coordinate and solve.

-6= -(1+1)^2 -2

-6= -(4) -2

-6 = -6
