Answer:
x > -7
Step-by-step explanation:
Step 1: Translate
Twice a number = 2x
Six more = + 6
At least = >
-8 = -8
Step 2: Write out inequality
2x + 6 > -8
Step 3: Solve
2x > - 14
x > -7
Answer:
Step-by-step explanation:
Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so
An aircraft has a maximum of 220 economy seats
A flight will be cancelled if the money taken for the seats is less than $28,800.
so
therefore
Three inequalities that represent the situation are
Answer:
1.) Arithmetic sequences are modeled with linear functions because it is a linear series
2.) Geometric sequences are modeled with exponential functions because their value increases exponentially
Step-by-step explanation:
1.) Arithmetic sequences are linear functions. While the n-value increases by a constant value of one, the f (n) value increases by a constant value of d, the common difference.
Arithmetic Sequence is one where you add (or subtract) the same value to get from one term to the next.
2.) An exponential function is obtained from a geometric sequence by replacing the counting integer n by the real variable x. Geometric sequences (with common ratio not equal to −1, 1 or 0) show exponential growth or exponential decay, as opposed to the linear growth (or decline) of an arithmetic progression such as 4, 15, 26, 37, 48, … (with common difference 11).
This shows that Geometric series grow or decays (reduces) exponentially; this is due to their common ratio (r)
