Solve the following in-equations and graph the solution on the number line

OverLord2011 [107]

Answer:

Step-by-step explanation:

$\frac{x-4}{3}$ ≥ - 2

x - 4 ≥ - 6

x ≥ - 2

x ∈ [ - 2 , ∞ )

2 - 6x < 32

- 6x < 30

x > - 5

I'll mark as Brainliest, Please answer ASAP, Ihave MCAS tomorrow. How could this be true?? Please Explain.

Vaselesa [24]

Answer:

See below

Step-by-step explanation:

The number of loaves of bread remaining can only go as low as ZERO (you can't have negative loaves) ...and can only go as high as when h = 0

so 0 = 42-3.5 h

3.5 h = 42

h = 12 and min is h = 0 ( when there are 42 loaves to start)

So:

0≤ h ≤ 12

Determine the kinetic energy of a 100-kg roller coaster car that is moving with a speed of 20.0/ms.

rjkz [21]

Answer:

The kinetic energy is 20,000\ J

Step-by-step explanation:

The kinetic energy of a body is defined as:

$k = \frac{1}{2}ms ^ 2$

Where m is the mass of the roller coaster car

s is the speed and k is the kinetic energy

We know that $s = 20\ m/s$

$m = 100\ kg$

Then the kinetic energy of the roller coaster car is:

$k = \frac{1}{2}(100)(20) ^ 2\\\\k = 50(20) ^ 2\\\\k = 50 * 400\\\\k = 20,000\ J$

Answer:

x = 20

Step-by-step explanation:

Traingle ABC = Traingle DEC

4x-1×4×5 = x+2×4×5

80x-1 = 2×20x

80x-20x = 2+1

60x = 3

60÷3 = x

x = 20
