2x + y = 8 find four solutions
Tcecarenko [31]

Answer:

see explanation

Step-by-step explanation:

Choose any value for x, substitute into the equation and solve for y, that is

x = - 1

2(- 1) + y = 8

- 2 + y = 8 ( add 2 to both sides )

y = 10

---------

x = 0

2(0) + y = 8

0 + y = 8

y = 8

----------------

x = 1

2(1) + y = 8

2 + y = 8 ( subtract 2 from both sides )

y = 6

---------------

x = 3

2(3) + y = 8

6 + y = 8 ( subtract 6 from both sides )

y = 2

----------------

4 possible solutions are (- 1, 10 ), (0, 8 ), (1, 6 ) and (3, 2 )

WhaT is the sum of the first 6 terms of this geometric system<br> -5,10,-20,40,...
jeyben [28]
Each one is multiplied by -2...

PROOF
-5 * 10 = -20
-20 * -2 = 40
And so on.

So we need two more numbers so do 40 * -2...

40 * -2 = -80

And then...
-80 * -2 = 160

So the first 6 numbers are...
-5, 10, -20, 40, -80, 160.

We need to find the SUM, which is all the numbers added together.

-5 + 10 - 20 + 40 - 80 + 160 = 105

105 is your answer.

1. One rule of thumb for estimating crowds is that each person occupies 2.5 square feet. Use this value to
givi [52]

Answer:

216 people

Step-by-step explanation:

Given:

2.5 feet² is occupied by 1 person

Dimension of room = 216 in × 360 in

Required:

No. of people that would occupy the room

SOLUTION:

Step 1:

Convert the dimensions of the room from in to ft

Note: 1 foot = 12 inches

216 inches = \frac{216}{12} = 18 ft

360 inches = \frac{360}{12} = 30 ft

Step 2: calculate area of the room.

Area of the room = 30*18 = 540 ft²

Step 3: calculate the no. of people the room will contain.

2.5 ft² will contain one person

Therefore, 540 ft² will contain: \frac{540}{2.5} = 216 people
