Rules for Graphing an Inequality 1. Place a on the number line for the number in the expression.
• Open circles for strictly and
• for less than or equal to and greater than or equal to.
2. Draw a line to the left or right to show all the for the inequality.

Step-by-step explanation:

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
