Answer:

Your answer is C.

Step-by-step explanation:

3.4 μm mean 3.4 Micrometers. Wow, that's pretty small.

A and B can instantly be ruled out, since it's micrometers, which are far smaller than meters. And 1 meter is 1e+6 times bigger than a micrometer, which makes D easily ruled out. The only answer you are left with is C, which is correct.

Match the following items by evaluating the expression for x = -2.
Sloan [31]

Answer:

1)  -4

2) -3

3) 1

4) -2

5) 4

Step-by-step explanation:

According to the information given in the exercise, the value of "x" is:

x = -2

Then:

1) You must substitute  x = -2 into the expresion x-2:

=(-2)-2

Now, you must evaluate:

=-4

2) You have to substitute the given value of "x" into the second expression:

x-1=(-2)-1

Finally, evaluating, you get the following result:

=-3

3) According to the Zero exponent Rule, any non-zero number with an exponent of zero is equal to 1.

Then, substituting x = -2 into the expression x^0 and then evaluating, you get:

x^0=(-2)^0=1

4) By definition:

 a^1=a

Then, substituting   x = -2 into x^1 and evaluating, you get:

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

5) Since:

 a^2=a*a

When you substitute the given value of "x" into the last expression and then  you evaluate, you get:

x^2=(-2)^2=(-2)(-2)=4

Show work please and thanks!

Hello there!

On those type of angles, the angles that are facing each other is equal to another.
So you can set up the equation like this : 

10x + 1 = 12x - 5
        -2x = -6
          x = 3

So the answer is x = 3.



In some problems, you have to find the angle.
Then you just simply substitute 3 into x.

10x + 1
10(3) + 1
30 + 1
31

12x - 5
12(3) - 5
36 - 5
31
The angles are 31° and 31°.

Hope this helped! :)

Only answer number one
Gemiola [76]

Answer:

George is right

Step-by-step explanation:

(0,5) and (4, 3)

m= (y2-y1)/(x2-x1)

m = (3-5)/(4-0)

m = (-2)/4

m = -1/2

Chrissie's slope: 1/2

George's Slope: -1/2

George is correct because the slope is -1/2 after completing the slope formula
