Answer:
no solution
Step-by-step explanation:
Simplifying the given equation, you have ...
-6(x -2) +3x = -3(x +3) +21 . . . . . given
-6x +12 +3x = -3x -9 +21 . . . . . . eliminate parentheses
-3x +12 = -3x +13 . . . . . . . . . . . . collect terms
0 = 1 . . . . . . . . . . . . . add (3x-12) to both sides
There is no value of x that will make this true.
The equation has NO SOLUTION.
Answer:
The first option.
Step-by-step explanation:
When graphing inequalities on a number line, a solid circle indicates that the number is part of the solution, while an open circle does not count that number as part of the solution.
Drawing a line to the left of the circle means that the solution includes values less than the circled number. Drawing a line to the right means that the included values are greater than the circled number.
I hope this helped :)
Answer:
[8i + 54j + 72k] joules per newton metre square.
Step-by-step explanation:
F(x,y,z) = z2i + 3xyj + 3y2k
F(3,0,0) = 0
F(3,3,1) = 1(2i) + 3(3)(3)j + 3(3)(2k)
= 2i + 27j + 18k
F(0,3,1) = 1(2i) + 3(0)(3)j + 3(3)(2k)
= 2i + 18k
The sum = [4i + 27j + 36k]
Since the particle moves back to the origin, we multiply the above Work Done by 2:
[8i + 54j + 72k]
And since work done is the product of Force and Distance, the S.I. unit is Joules/newton metre square
