Answer:

Step-by-step explanation:

f(n)=64+6n

f(n-1)=64+6(n-1)=64+6n-6=f(n)-6

f(n-1)+6=f(n)

or f(n)-f(n-1)=6

The rectangle below has a area x^2-x-72 square meters and a length of x+8 meters what expression represents the width of the rec
mixer [17]
ANSWER

w = (x - 8)

EXPLANATION

The given rectangle has area,

A = {x}^{2} - x - 72 \: {m}^{2}

It was given to us that, the length of the rectangle is l=(x+8)

To find the width, we need to factor, the expression for the area.

We split the middle term to get,

A = {x}^{2} - 9x + 8x- 72

We now factor by grouping;

A = x(x - 9) + 8(x- 9)

A = (x + 8)(x - 9)

We know that area of a rectangle is

A = l \times w

Hence the width of the rectangle is,

w = (x - 8)

Help plzz i will give you brianliest Which best describes the graph of the function f(x) = 3(1.8)^x A) The graph passes through
DanielleElmas [232]

Answer:

Step-by-step explanation:

Start with why C isn't the answer.

y = 1.8^0 . The power is zero. Anything to the zero power (anything except 0 to the 0 power) is 1. So 1.8^0 is 1 not something else. C assumes that somehow 0,1.8 turns into 1.8. It does not. The second part is also wrong but you don't need it. However here it is.

x = 0        y = 3

x = 1         y = 3 * 1.8 = 5.4

x = 2        y = 3 * 1.8^2 = 3*3.24 = 9.72

You should be able to see that if you multiply 5.4 by 3, you don't get 9.72

C just does not work.

=======

The actual answer is A. That's exactly what the graph does. If you multiply 5.4 * 1.8 you should get 9.72. Just for completeness, I've included the graph.

Best answer gets Brainliest!!!
Murrr4er [49]

Answer:

The table C

Step-by-step explanation:

when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality  is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.
