Distribute 2 to x and -2, and -6 to x and -2

2(x - 2) = 2x - 4

-6(x - 2) = -6x + 12

2x - 4 = 4x - 6x + 12

Simplify. Combine like terms

2x - 4  = (4x - 6x) + 12

2x - 4 = -2x + 12

Isolate the x. Add 4 to both sides, and 2x to both sides

2x (+2x) - 4 (+4) = -2x (+2x) + 12 (+4)

2x + 2x = 12 + 4

Simplify

4x = 16

Isolate the x. Divide 4 from both sides

4x/4 = 16/4

x = 16/4

x = 4

4 is your answer for x.

hope this helps

Which is equivalent to sqrt x^10<br> A. X-5<br> B. X -1/5<br> C. X sqrt 10<br> D. X 1/5<br> E. X^5
Lesechka [4]
<h3>Answer:  E) x^5</h3>

\sqrt{x^{10}} = x^5

=====================================================

Explanation:

We simply take half of the exponent 10 to get 5. This applies to square roots only.

So the rule is \sqrt{a^b} = a^{b/2}

A more general rule is

\sqrt[n]{a^b} = a^{b/n}

If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.

PLEASE HELP ASAP!! You used your new smart watch to record your heart rate every morning for 15 days. Select the dot plot that r
Artyom0805 [142]

The dot-plot for the data is sketched at the end of this answer.

--------------------------

  • The dot plot shows the <u>number of times each measure appears in the data-set.</u>

<u />

  • 68 appears once, thus it is 1 in the dot-plot.
  • 69 appears three times, thus it is 3 in the dot-plot.
  • 70 appears once, thus it is 1 in the dot-plot.
  • 71 does not appears, so it is 0.
  • 72 appears once, thus it is 1 in the dot-plot.
  • 73 appears five times, so it is 5 in the dot-plot.
  • 74 appears once, thus it is 1 in the dot-plot.
  • 75 does not appears, so it is 0.
  • 76 appears twice, thus it is 2.
  • 77 appears once, so it is 1.

The sketch is given at the end of this answer.

What is the rate of change of the volume of the cylinder at that instance (in cubic kilometers per second)?
Kay [80]

Answer:

hello your question is incomplete attached below is the complete question

answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = d(\pi r^h ) / dt  

              = \pi h\frac{d(r^2)}{dt}  = -\pi h *2r *dr/dt

hence ; dv / dt = -2400 π
