(6,10) (12, 0) 8 10 (0,0) What is the equation

For a fixed amount of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. The functi

malfutka [58]

The relation between pressure and volume is given as
v = 18000/p
where
v = volume, in³
p = pressure, lb/in²

When the pressure is p = 900 lb/in², then the volume is
v = 18000/900 = 20 in³

Answer: 20 in³

Solve for x. -2(16 - 4x) - 8 = 6(x + 2)

Amanda [17]

So...

-2(16-4x)-8=6(x+2)            Multiply
-32+8x-8=6x+12                 Add like terms
-40+8x=6x+12                    Subtract 6x from both sides
-40+2x=12                          Add 40 to both sides
2x=52                                 Divide 2 from both sides
x=26                                   Substitute to check
-2(16-4(26))-8=6((26)+2)   Add and multiply in parenthesis
-2(-88)-8=6(28)                  Multiply
176-8=168                         Subtract
168=168

So x=26

I hope this helps! Have a great day!

ira [324]

Answer:

He won 13 times and lost 1 time

Step-by-step explanation:

divide 67 by 5 so 67÷5 you would get 13.4 you take the whole number 13 and multiply it by 5 and that will get you to 65 so then you only have 2 left over and if you lose you get 2 point so therefore you know that he lost only once

(13•5)+2=67

Over which interval is the graph x^2+3x+8 increasing

vladimir1956 [14]

F(x) = x^2+3x+8

now, the pending of the tangent line is d/dx f(x)
f'(x) = 2x + 3
now, we need know when the pending is increasing.
so
2x + 3> 0

solving
x>-3/2

The interval over which the function f(x)= x^2+3x+8 is increasing is (-3/2,+∞)

According to a survey of 100 people regarding their movie attendance in the last year, 40 had seen a science fiction movie, 50 h

Anarel [89]

Answer:

Kindly check attached picture ; 37.5%

Step-by-step explanation:

Let:

S = number of science fiction movie viewers

H = number of horror movie viewers

A = number of adventure movie viewers

From the information given :

n(SnHnA) = 5

n(SnH) only = 15 - 5 = 10

n(SnA) only = 25 - 5 = 20

n(AnH) only = 5 - 5 = 0

n(S) only = 40 - (10+5+20) = 5

n(H) only = 40 - (10+5+0) = 25

n(A) only = 50 - (5 + 20 + 0) = 25

2.) % of science fiction movie to horror movie fans

Total Science fiction movie fans = n(S) = 40

Science fiction and Horror movie fans = n(SnH) = 15

[n(SnH) / n(S)] * 100%

(15 / 40) * 100%

0.375 * 100%

= 37.5%
