Math Unit 4

Front 1

F = 9/5 C + 32

Back 1

is used to Convert c to f

Front 2

c= 5/9 f - 32

Back 2

is used to Convert f to c

Front 3

In an arithmetic sequence, the difference between every pair of consecutive terms is the same

Back 3

true

Front 4

The common difference of a sequence can be found by subtracting any term from the term that follows it

Back 4

true

Front 5

In a geometric sequence, there is a common ratio between each pair of consecutive terms in the sequence. So to find the common ratio of a sequence, simply divide any term by the previous term

Back 5

true

Front 6

a n = a 1 + d(n - 1),

Back 6

formula for solving the arithmetic sequence

Front 7

n-1

a n = a 1 · r

Back 7

formula for solving a geometric sequence

Front 8

a n represents the value of the nth term, a 1 represents the value of the first term, r represents the common ratio, and n represents the term number

Back 8

true

Front 9

You solve inequalities using the same process you used for solving equations. The only difference is that the inequality symbol must be flipped if both sides of the inequality are multiplied or divided by a negative number.

Back 9

true

Front 10

Solve the inequality 3 > x/-2 and graph the solution on a number line.

Solution:
The variable x is being divided by -2. To solve, multiply both sides of the inequality by -2. Since you need to multiply both sides by a negative number, you'll also flip the inequality symbol.
