Answer:

5(k + 1) and 5k + 5

Step-by-step explanation:

The easiest way to do this is to pick any number to substitute in for the variable <em>k </em>for ALL of the expressions, and find the expressions that equal the same as the first expression being compared.

For example, lets just make <em>k </em>equal 1 to make things easy. Plug 1 into <em>k</em> into the first expression. 2k + 2 + k + 3 + 2k → 2(1) + 2 + (1) + 3 + 2(1) = 10.

Now we do the same to the rest of the expressions and see which ones ALSO equal 10.

5(k + 1) → 5(1 + 1) = 10

5k + 5 → 5(1) + 5 = 10

5 + k^5 → 5 + (1)^5 = 6

5k^5 → 5(1)^5 = 5

3. Factor.
sleet_krkn [62]
It seems that some the work is already here, but I'd be glad to!! So for #3 which is 9x^2+15x, we can factor out both a 3 and an x (3x) so we know that 3x * 3x =9x^2 and 3x * 5 = 15x so once we take the 3x out of the equation, we are left with 3x(3x+5) and that's as far as you can factor.
For #4, we see that the common factor is 10m because 10m * 2n = 20mn and 10m * 3 = 30m so once we take 10m out of the original, it becomes 10m(2n-3)
For #5, this one the common factor is 4xy because 4xy * 2xy=8x^2y^2 and 4xy*x= 4x^2y and 4xy*3=12xy so once we take the 4xy out of the equation, it becomes 4xy(2xy-x-3)
Hope this helps!

Answer:

It will earn an additional $71.94.

Step-by-step explanation:

First, figure out what 1% of 720 is by dividing 720 by 100 to get 7.2. Then you add 7.2 to 720 to get 727.2. Then you find 1% of the new total and repeat the process.

Which is the graph of g(x) = ⌈x + 3⌉?
koban [17]

Answer:

I can not tell what the graphs are but you would set up a table and plug it into the x value to calculate the y value

Step-by-step explanation:

____x_________y_______

3                  !

2                  !

1

0

-1

-2

-3

this is assuming that your brackets would be a straight lines which would be an absolute value  

if this is the case, then no matter what the answer for y is . . .Y would always be a positive number with the exception of the 3 or the negative three that would result in a 0 value

I hope this helps
