What is the value of x? 3x + (6x - 6) = 4(2x-2)

Mathematics
1 answer:

8 0

Answer:

x = -2

Step-by-step explanation:

To start, let's add on the first side to get 3x + 6x - 6 = 9x - 6. For the second side, we need to distribute the 4 to get 4(2x) + 4(-2), or 8x + (-8) or 8x - 8. Setting these equal, we subtract 8x from both sides to get x - 6 = -8, and adding 6 to both sides gives x = -2.

Explain how to solve for the rate in a simple interest equation if you are given the interest amount, the principal, and the tim
FrozenT [24]

Answer:

divide the interest amount by the product of the principal and time

Step-by-step explanation:

The simple interest formula is I = prt where I is the interest, p is the principal, r is the rate and t is the time (in years). Rewriting this formula so that r is the subject we get r = I / pt. Therefore the answer is divide the interest amount by the product of the principal and time.

Resuelve el siguiente ejercicio de velocidad. El vector de posición de un móvil es r (t) =2 (t −7) i +12t j, en intervalos de ti
krek1111 [17]

To Find :

Position vector at time t_1  = 5\ s and t_2 = 8\ s.

Solution :

r (t) = 2 (t −7)i + 12t j

Putting t = 5 s and t = 8 s, we get :

r(5) = 2( -2 )i + 60j

r(5) = -4i + 60j

r(8) = 2i + 96j

Now, to find speed differentiating the r(t) w.r.t t :

v=\dfrac{dr}{dt}= \dfrac{d(2(t-7)i + 12tj)}{dt}\\\\v=\dfrac{dr}{dt}= 2i + 12j

Hence, this is the required solution.

Triangle inequality theorem-are the lengths 7, 4, and 2 of a triangle possible?
kakasveta [241]

You can't make a triangle with those lengths for sides.

The way I look at it is like this:

-- Take  2  sticks ... lengths  4  and  2  ... and connect them together at one end.

-- The farthest they can reach, if they're opened up completely and pointing
in opposite directions, is a distance of  6 .

-- They can't reach the ends of a stick that is  7  long.  So you can't make
a triangle with those  3  sticks.
