Answer:

tn=9+3(n-1)

Step-by-step explanation:

Formula: tn=t1+d(n-1)

AKA: term n=term 1 plus common difference times n minus 1

For this sequence: tn=tn; t1=9; common difference=3; n-1=n-1

Plug in the answer: tn=9+3(n-1)

What is the perimeter, in units, of polygon UVWXYZ? Enter your answer in the box.
nikitadnepr [17]

Given:

Consider the below figure attached with this question.

To find:

The perimeter of the polygon UVWXYZ.

Solution:

All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.

From the figure it is clear that,

UV = 9 units

VW = 2 units

WX = 3 units

XY = 3 units

YZ = 6 units

ZU = 5 units

Now, perimeter is the sum of all the sides.

Perimeter=UV+VW+WX+XY+YZ+ZU

Perimeter=9+2+3+3+6+5

Perimeter=28

Therefore, the perimeter of UVWXYZ is 28 units.

If f(x) = 9x - 2 and g(x) = 2x², what is the value of f(4) - g(4)
pishuonlain [190]

9514 1404 393

Answer:

  f(4) -g(4) = 2

Step-by-step explanation:

Fill in the given values for x and do the arithmetic.

  f(4) = 9·4 -2 = 34

  g(4) = 2·4^2 = 32

Then ...

  f(4) -g(4) = 34 -32

  f(4) -g(4) = 2

How many solutions are there to the following system of equations?
blagie [28]
Lets simplify these equations into slop-intercept form (y=mx+b)

When we do that, the equations turn to

y=-6x/24+10/6  or y=-1/4*x+5/3
y=-2x/8+7/8      or y=-1/4*x+7/8

When you do this, you see that the slope (m) is the same. This means that they are parallel lines. That means these lines will never meet, which means there will be no solution
