Answer:

Answer:

Step-by-step explanation:

y = 15x

y = 10x + 100

15x = 10x + 100

5x = 100

x = 20 movies

Answers

Answer:

It is 10 (m=10)

Step-by-step explanation:

3 (10-2) + 14                  Subtract whats in the parentheses

3 (8) + 14                        Multiply 3 and 8

24 + 14                             Add the remaining to get the sum ( 24 + 14 )

If a flexible air-filled container has a volume of 40 cu ft on the surface, what would the volume be at 99 feet in sea water

Answers

The volume of flexible air filled container at 99 feet in sea water is 10 cu.ft.

What is Boyle's law?

Boyle's Law states that If the temperature is constant, the volume of a  gas is inversely proportional to the absolute pressure.

V 1/V2 =P2/P1

V2 = P1 x V1 /P2

Substitute 60 psi for P2, 14.7 psi for P1 and 40cu.ft for V1, we get the volume V2

V2 = 40 x 14.7 / 60

V2 = 9.8 cu.ft

Volume is approximately 10 cu.ft.

Thus, the volume of flexible air filled container at 99 feet in sea water is 10 cu.ft.

What is the LCD of 8 5/12 and 3 5/8?

Answers

The lowest common denominator of those two numbers is 12.

8 5/12 = 8 10/24
3 5/8 = 3 15/24

Answer:

12

Step-by-step explanation:

Input the equation of the given line in slope intercept form. The line through 1,0 and parallel to x-y=7

Answers

x - y = 7
y = x - 7....the slope here is 1. A parallel line will have the same slope.

y = mx + b
slope(m) = 1
(1,0)...x = 1 and y = 0
now we sub and solve for b, the y int
0 = 1(1) + b
0 = 1 + b
-1 = b

so ur parallel line is : y = x - 1

We know that a parallel line has the same slope. And the slope-intercept form in y=mx+b.

1. simplify x-y=7 to isolate y.

subtract x:    -y=-x+7

then divide by -1:  y=x-7

so the slope is 1 (m=1)

2. plug in m=1 and (1,0)           *******alternate solution below

0=1(1)+b

0=1+b    subtract 1

-1=b    (b=-1)

3.  y=mx+b plug in numbers. ( in bold)

y=1x-1

your answer is y=x-1

*****alternate answer solution from step 2 (using step 1)

2. use the formula y-y1=m(x-x1) (y1 and x1 is with the 1 below the letters BTW)

plug in (1,0)

y-0=1(x-1)

y=1x-1

y=x-1 is your answer.

So it comes out as the same answer. Just 2 different ways to doing it! :)
