Answer:

-300

Step-by-step explanation:

A counter-clockwise rotation is positive.

A clockwise rotation is negative.

Start at the top and go counter-clockwise 60 degrees.

Start at the top and go clockwise 300 degrees.

You end up at the same point.

It is -300 because a clockwise rotation is negative.

What is the slope of the line that passes through the points (6-8) and (10,-8)?

romanna [79]

Answer:

The slope of the line that passes through the points would be 0

Step-by-step explanation:

Lets use the formula : y2-y1/x2-x1

In this case lets let y2 be -8 and y1 be -8

And lets let x2 be 6 and x1 be 10, that would look like..

-8-(-8)/6-10

which equals...

0/-4 = 0

We know that the slope of the line is 0

What are the zeros of this function ?

Montano1993 [528]

The zeroes are where the graph hits the x axis (left and right)

that ocurs at x=0 and x=5

so answer is A

Which two steps should be used first in solving the system of equations

Inessa05 [86]

Answer:

The value of x , y using substitution method is 2 , 5

Step-by-step explanation:

Given as :

The two linear equation as

6 y - 4 x = 22 .......1

y + 2 x = 9

Let y = 9 - 2 x .......2

Now, using substitution method

Substitute the value of y from eq 2 into eq 1

i.e 6 × (9 - 2 x) - 4 x = 22

Or, 54 - 12 x - 4 x = 22

Or, 12 x + 4 x = 54 - 22

Or, 16 x = 32

∴ x = $\dfrac{32}{16}$

i.e x = 2

Now, Put the value of x into eq 2

∴ y = 9 - 2 x

So, y = 9 - 2 × 2

Or, y = 9 - 4

i.e y = 5

So, The value of x , y = 2 , 5

Hence, The value of x , y using substitution method is 2 , 5 Answer

Solve each of the following equations. Show its solution set on the number line. Check your answers. a 2(x−1) =11

adelina 88 [10]

You distribute the 2 to both numbers to get 2x-2=11, move the 2 to the other side by adding it to the 11. 2x=13. Divide 13 by 2, and X=6.5

Darla found that the least common denominator needed to subtract \frac{x}{x^2+4x-12}-\frac{3}{x+6}is (x + 6)(x – 2). Which is th

Leona [35]

<h3>Answer: Choice B</h3>

$\frac{x}{(x+6)(x-2)} - \frac{3(x-2)}{(x+6)(x-2)}$

which is the same as x/((x+6)(x-2)) - 3(x-2)/((x+6)(x-2))

=====================================

Explanation:

The LCD is (x+6)(x-2) which is the factorization of x^2+4x-12, and that is the denominator of the first fraction. The first fraction has the LCD already. The second fraction does not. It has (x+6) but it is missing (x-2).

We multiply top and bottom of the second fraction by (x-2) to get the second fraction to have the LCD.

$\frac{3}{x+6}$ turns into $\frac{3}{x+6}*\frac{x-2}{x-2} = \frac{3(x-2)}{(x+6)(x-2)}$

------

So,

$\frac{x}{x^2+4x-12} - \frac{3}{x+6}$

$\frac{x}{(x+6)(x-2)} - \frac{3}{x+6}$

$\frac{x}{(x+6)(x-2)} - \frac{3(x-2)}{(x+6)(x-2)}$

This is the same as x/((x+6)(x-2)) - 3(x-2)/((x+6)(x-2))

Note the parenthesis around "(x+6)(x-2)"

Instead of x/(x+6)(x-2) you should write x/( (x+6)(x-2) ) to ensure that all of "(x+6)(x-2)" is in the denominator.
