You have to perform operations inside parenthesis first:

$6(5+4)=6\cdot 9$

And finally,

$6\cdot 9 = 54$

Distribute 6 to 5 and 4 by multiplying 6•5=30 and then 4•6=24 and then do 30+24 and you’re answer is 54

The graph of y=tan(x) is vertically stretched by a factor of 7, shifted a distance of 12 units to the left, reflected across the

Mekhanik [1.2K]

Step-by-step explanation:

A transformation(s) of a parent function is

$f(x) = a(bx - c) + d$

where a is vertical compression/stretched or reflection

B is horinzotnal compression/stretch or reflection

C is horinzontal translation

D is vertical translation.

The parent function is

$y = \tan(x)$

First, we stretched this by 7

so we have

$y = 7 \tan(x)$

We need to shift this 12 units to the left so we have

$y = 7 \tan(x + 12)$

We need to reflect this across x axis so we get

$y = - 7 \tan(x + 12)$

We need to shift this downwards 15 so we get

$y = - 7 \tan(x + 12) - 15$

or because tan is a odd function you could say

$7 \tan( - (x + 12) ) - 15$

$7 \tan( - x - 12) - 15$

Each side of the Pentagon Building in Washington DC is 900 feet long. What is the perimeter ?

Vika [28.1K]

The perimeter of a Pentagon is all the length of the sides added up
A pentagon is a five sided shape
so...
900+900+900+900+900
or 900*5
That is 4500.

The perimeter of the Pentagon Building in Washington DC, whose side is 900 feet long, is 4500 feet around.

Hope this helps :)

-the equations x-y=-14 and -x-y=14 what is the number of solutions? A.) no solutions B.) infinitely many solutions C.) one solut

Yuki888 [10]

Answer:

The answer is C one solution

Step-by-step explanation:

x-y=-14

-y=-x-14 bring x to the other side

y=x+14 divide everything by -1

-x-y=14

-y=x+14 bring x to the other side

y=-x-14 divide everything by -1

What is the image point of (-6, 9) after a translation left 4 uints and down 1 unit?

Alex17521 [72]

Answer:

(-10,8)

Step-by-step explanation:

So our original point is (-6,9).

A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.

A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.

Therefore, the new point would be:

$(-6-4,9-1)\\=(-10,8)$
