Answer:

$7x {}^{2} + 5x$

Step-by-step explanation:

$9x {}^{2} + 8x - (2x {}^{2} + 3x) \\ \\ = 9x {}^{2} + 8x - 2x {}^{2} - 3x (remove \: brackets) \\\ \\ = 7x {}^{2} - 5x$

Lemur [1.5K]

Answer:

Value of h greater than 5.4 will make inequality false.

Step-by-step explanation:

This question is incomplete; here is the complete question.

The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel 750 ≥ 75 + 125h. What value of h does NOT make the inequality true?

From the given question,

Per night expense (expected) = $125

If Jones family stays in the hotel for 'h' days then total expenditure on stay = $125h

Charges for scuba diving = $75

Total charges for stay and scuba diving = $(125h + 75)

Since Jones family has saved $750 for the vacation trip so inequality representing the expenses will be,

125h + 75 ≤ 750

125h ≤ 675

h ≤ $\frac{675}{125}$

h ≤ 5.4

That means number of days for stay should be less than equal to 5.4

and any value of h greater than 5.4 will make the inequality false.

Q#1: Suppose that you have two different algorithms for solving a problem. To solve a problem of size n, the first algorithm use

svetlana [45]

Answer:

The one of -[n+2n+3n+4n]/nlne(10) has fewer operations because the value of n is <u>static</u><u>.</u>

The one of n! ( factorial ) is factorised up to n∞ hence has infinity operations.

(A) How many ways can a 3-person subcommittee be selected from a committee of 6 people? (B) How many ways can a president co

Zepler [3.9K]

Answer:

A) N = 20 ways

a 3-person subcommittee can be selected from a committee of 6 people in 20 ways.

B)N = 120 ways

The president, vice president and secretary can be chosen from a committee of 6 people in 120 ways.

Step-by-step explanation:

A) the number of ways a 3-person subcommittee be selected from a committee of 6 people N;

Since there is no given order for the selection, this means that the order of selection is irrelevant. Therefore, this is a combination problem where order is not considered.

N = nCr

N = 6C3

N = 6!/3!(6-3)! = 6!/3!3!

N = 720/(6×6)

N = 20 ways

a 3-person subcommittee can be selected from a committee of 6 people in 20 ways.

B) the number of ways a president, vice president and secretary can be chosen from a committee of 6 people N;

In this case, there is a given order of selection for the 3 posts. This is a permutation.

N = nPr

N = 6P3

N = 6!/(6-3)!

N = 6!/3!

N = 120 ways

The president, vice president and secretary can be chosen from a committee of 6 people in 120 ways.
