Answer:

Step-by-step explanation:

X is an unknown variable so just leave x as it is

Because the (2x) and the (7x) are being multiplied together they are almost seen as their own category of things

Think about having two bananas in a bowl. I just threw in seven more to get a total of nine bananas in the bowl.

It's the same thing when you have a variable right next to a number! add them together as if they are alike terms.

2+7=9 therefore your answer should be 9x

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 – 10x?

Marina86 [1]

we have

$6 = x^{2}- 10x$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2}- 10x+25=6+25$

$x^{2}- 10x+25=31$

Rewrite as perfect squares

$(x-5)^{2}=31$

$(x-5)=(+/-)\sqrt{31}\\ x1=5+\sqrt{31} \\ x2=5-\sqrt{31}$

therefore

the answer is

the solutions are

$x1=5+\sqrt{31} \\ x2=5-\sqrt{31}$

How to somve this question

Dafna1 [17]

Answer:

-1

Step-by-step explanation:

The given function, f(x), has three distinct parts. We must find and choose the part whose domain includes x = 1.

This x = 1 is a member of the set 1 ≤ x < 2. Therefore, we choose the 2nd part of this function: evaluate -x^2 at x = 1. This comes out to -1^2, or -1. that's the second answer choice.
