A two column proof shows an algebraic step being taken, and then describes the step and how it's justified to the right.

A flowchart proof links each step to the next, with a brief description below it.

A paragraph proof describes each step in a group of text, written as a paragraph.

The number of tourists at the beach per weekend in July was 55,000, In November, the number of tourists per weekend was 18,000.
Ganezh [65]

Answer:

The percentage change from July to November is 67.27 %

Step-by-step explanation:

Given as :

The number of tourists at the beach per weekend in the month of July = x_1 = 55,000

The number of tourists at the beach per weekend in the month of November = x_2 = 18,000

Let the percentage change from July to November = A %

Or,  % decrease change = \dfrac{\tetxtrm new value - \textrm old value}{\textrm old value} × 100

So , A % = \dfrac{\tetxtrm [tex]x_2   - \textrm  x_1 }{\textrm  x_1 }[/tex] × 100

or, A % = \frac{55000 - 18000}{55000} × 100

Or, A % = \frac{37000}{55000} × 100

Or, A  = 67.27 %

So percentage change between two months = 67.27 %

Hence The percentage change from July to November is 67.27 % Answer

Solve using system of equations by using elimination method for -5x+4y=2 ; 9x-4y=6
jek_recluse [69]

Answer:

y = 3

x = 2

Step-by-step explanation:

-5x + 4y = 2

9x - 4y = 6

Sum both eq.

-5x + 9x = 4x

+4y - 4y = 0

2 + 6 = 8

then:

4x + 0 = 8

4x = 8

x = 8/4

x = 2

from the first eq.

-5x + 4y = 2

-5*2 + 4y = 2

-10 + 4y = 2

4y = 2 + 10

4y = 12

y = 12/4

y = 3

Check:

from the second eq.

9x - 4y = 6

9*2 - 4*3 = 6

18 - 12 = 6

Describe a relationship in which it would be reasonable to have a negative number in the domain or
Aliun [14]

Answer:

Relationship between temperature at different times of the day during the Winter period in places like Alaska and Minnesota in the USA.

Step-by-step explanation:

An example of a relationship that would have a negative number in the domain or range would be the relationship between the temperature at different times of the day during the snow period in the winter. It's well known that in places like Alaska and Minnesota in the USA, that during the winter when there's very heavy snow, the average temperature is usually below 0°C. The temperature is the dependent variable and is most likely negative in those 2 states and thus the range would have negative numbers.
