Solve the following systems of inequalities and select the correct graph:
zaharov [31]
We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2

So the solution of this system of equation is the coordinate (1, -2)

You are having a family meeting during the a epidemic. You want to follow the guidelines and know everyone has to stay 6 feet ap
Lady_Fox [76]

Answer:

a.

Total No. of People = 8 people

b.

Total No. of People = 6 people

Hence, we can not fit the same amount of people in both rooms.

Step-by-step explanation:

a.

Here, the dimensions of the room are 12 ft by 24 ft. So, in order to maintain the 6 ft distance, we can allow following number of people in it.

No. of people along 24 ft dimension = 24 ft/6 ft

No. of people along 24 ft dimension = 4

No. of rows along 12 ft dimension = 12 ft/6 ft

No. of rows along 12 ft dimension = 2

So, the total no. of people is given as:

Total No. of People = (People along 24 ft)(Rows along 12 ft)

Total No. of People = (4)(2)

<u>Total No. of People = 8 people</u>

<u></u>

b.

Here, the dimensions of the room are 16 ft by 18 ft. So, in order to maintain the 6 ft distance, we can allow following number of people in it.

No. of people along 16 ft dimension = 16 ft/6 ft

No. of people along 16 ft dimension = 2.67

In order to maintain minimum 6 ft distance the no. of people is rounded down to 2.

No. of people along 16 ft dimension = 2

No. of rows along 18 ft dimension = 18 ft/6 ft

No. of rows along 18 ft dimension = 3

So, the total no. of people is given as:

Total No. of People = (People along 24 ft)(Rows along 12 ft)

Total No. of People = (2)(3)

<u>Total No. of People = 6 people</u>

<u>Hence, we can not fit the same amount of people in both rooms.</u>

<u></u>
