Answer:

x=13

Step-by-step explanation:

We add all the numbers together, and all the variables

6x-78

We move all terms containing x to the left, and all other terms to the right

6x=78

x=78/6

which should equal 13

Step-by-step explanation:

OMG!!!!! why don't you just SAY YOU WANT a BLEEPING REFLECTION!!!

I had to search through a slew of your questions to get clues as to what to do.

To reflect over the x axis, just negate the y term and leave the x term as it is.

M becomes (2, -1)

N becomes (-3, -1)

P becomes (-1, -4)

A shelf is designed so it will fit in a 90º corner between two walls. The shelf has dimensions, rounded to the nearest tenth, as

den301095 [7]

Answer:

Yes, it will fit snugly in a 90º corner

Step-by-step explanation:

To do this, we simply need to check if the given sides of the shelf is right-angled.

So, we have:

$Hypotenuse = \sqrt{242$

$Side\ 1 = Side\ 2 = 11$

To check for right-angle triangle, we make use of:

$Side\ 1^2 + Side\ 2^2 = Hypotenuse^2$

This gives:

$11^2 + 11^2 = \sqrt{242}^2$

$121 + 121 = \sqrt{242}^2$

$242 = \sqrt{242}^2$

$242 = 242$

This shows that the given sides of the shelf is a right-angled triangle.

Hence, it will fit the wall

Answer:

-31

Step-by-step explanation:

(2×x) - (2×5) = (3×x) + (3×7)

2x-10 = 3x+21

2x-3x = 21+10

-x = 31

therefore, x = -31
