Answer:

x > 1

interval (1,∞)

Step-by-step explanation:

1/2(-2x - 12) > 7(3 - 4x)

-x - 6 > 21 - 28x

-x + 28x > 21 + 6

27 x > 27

x > 27 / 27

x > 1

interval (1,∞)

-x - 6 > 21 - 28x     if x = 2

-2 - 6 > 21 -28(2)

-8 > 21 - 56

- 8 > - 35

Find the distance between the two points rounding to the nearest tenth (if necessary). (-7, -5)(-3, 4)
aleksklad [387]

Answer:

9.8 ( to the nearest tenth )

Step-by-step explanation:

calculate the distance using the distance formula

d = √( x₂ - x₁ )² + ( y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, - 5) and (x₂, y₂ ) = (- 3, 4)

d = \sqrt{(-3+7)^2+(4+5)^2} = \sqrt{16+81} = \sqrt{97} = 9.8

Ad libitum [116K]

Answer:

0.72\,\,m^3

Step-by-step explanation:

Given:

Length of a rectangle solid = 3 m

Width of a rectangle solid = 0.6 m

Height of a rectangle solid = 0.4 m

To find: Volume of the solid

Solution:

Volume of the solid = length × breadth × height

=3\times 0.6\times 0.4=0.72\,\,m^3

So, the number of cubic meters in the volume of the solid is 0.72\,\,m^3
