For question number 2, the answer is A 6x+9

Explanation:

$\begin{gathered} 3(2x+3) \\ \text{Clearing the brackets, we get} \\ 6x+9 \end{gathered}$

Question Number 19:

$\begin{gathered} 8x-2x+4 \\ 6x+4 \\ \text{Factorizing, we get} \\ 2(3x+2) \end{gathered}$

So, the correct answer for question number 19 is 6x + 4.

write the first five terms of the sequence defined by the recursive formula a_n=(5a_n-1)-1, with a_1=0

nadezda [96]

Answer:

a_1 = 0

a_2 = -1

a_3 = -6

a_4 = -31

a_5 = -156

Step-by-step explanation:

a_n=(5a_n-1)-1

a_1 = 0

to find a2 substitute a1

a_2 = (5* a_1)-1

a_2 = 5* 0 -1

a_2 = 0-1

a_2 = -1

to find a3 substitute a2

a_3 = (5* a_2)-1

a_3 = (5* -1 ) -1

a_3 = -5 -1

a_3 = -6

to find a4 substitute a3

a_4 = (5* a_3)-1

a_4 = (5* -6 ) -1

a_4 = -30 -1

a_4 = -31

to find a5 substitute a4

a_5 = (5* a_4)-1

a_5 = (5* -31 ) -1

a_5 = -155 -1

a_5 = -156

Where would you plot the vertex on the graph of the following absolute value equation? enter your answer as an ordered pair (x,y

makvit [3.9K]

Answer:

The absolute value vertex is (5, 10). Please check that graph is also attached for the absolute equation with vertex (5, 10).

Step-by-step explanation:

Considering the absolute value equation

$y=|x-5|+10$

To find the x coordinate of the vertex, set the inside of the absolute value $x - 5$ equal to zero.

In this case,

$x - 5=0$

$x=5$

Replace the variable x with 5 back into the equation and solve for y.

$y=|(5)-5|+10$

$y=0+10$

$y = 10$

Therefore, the absolute value vertex is (5, 10). Please check that graph is also attached for the absolute equation with vertex (5, 10).

A standard deck of playing cards contains 52 cards, equally divided among four suits (hearts, diamonds, clubs, and spades). Each

Svetradugi [14.3K]

The order does not matter, so we will be using combinations here. 52C1 is the first one since there is only one possibility. 16C1 is the second. You have to multiply these two, so 52 X 16 = 832.
