Answer:
x < -7
Step-by-step explanation:
-4x > 28
-x > 7
x < -7
Answer:
x is less than or equal to negative 14.
Step-by-step explanation:
so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side
remove 5 from each side
-x/3=1/3-5
-x/3=14/3
multiply both sides by 3
-x=14
x=-14
so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14
Depends on what kind of a triangle
There's a formula for that.
KE = (1/2)mv²
... = (1/2)(2000 kg)(30 m/s)²
... = 900,000 kg·m²/s²
... = 900,000 J
_____
It is helpful to know the relationship between kilograms, meters, seconds, and Newtons or Joules.
1 J = 1 kg·m²/s²
Answer: Is the last one. D
