Answer:

B. arithmetic sequence; 9

Step-by-step explanation:

An arithmetic sequence is a sequence where there is a common difference between each term. A common difference is a number that is added to the previous term to get the current term. For a sequence to be considered arithmetic this common difference must remain constant. This sequence is arithmetic because each time 9 is added to the previous term to get the next one. So the common difference is 9 and B is correct.

siniylev [52]

Answer:

The percentage decrease is -33.93%

Step-by-step explanation:

Firstly we check if there is an increase or decrease

Since we went from 5.5 million to 3.7 million, that is a decrease

Percentage decrease = (3.7 - 5.6)/5.6 * 100%

= -1.9/5.6 * 100% = -33.93%

Solve forx: x^2 = 5x
Akimi4 [234]

Answer:

x = 5

x = 0

Pulling out like terms :

2.1     Pull out like factors :

  x2 - 5x  =   x • (x - 5)

Equation at the end of step  2  :

 x • (x - 5)  = 0

Step  3  :

Theory - Roots of a product :

3.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.
