How to solve |2x-4|=8

Mathematics
2 answers:
zaharov [31]3 years ago

Ok... let's break it apart and put it back together.

There's an absolute value... "2x-4" is inside the absolute value. The absolute value of "2x-4" is equal to the value of 8... so find x.

There are TWO cases:

(2x-4)=8
    OR
 -(2x-4)=8 

Now you should be able to solve it. If you can't... well, just ask me below. I can't do ALL the work, can I?

|2x - 4| = 8 ⇔ 2x - 4 = -8 or 2x - 4 = 8  |add 4 to both sides

2x = -4 or 2x = 12    |divide both sides by 2

x = -2 or x = 6

If I toss a fair coin in real life and I get two heads in a row, does that change the probability of getting one tail in every t
stepladder [879]
Getting two heads in a row does not change the probability of getting a tail. There is a 50/50 chance for both heads and tails each time you flip a coin, because there are two possibilities each equally possible. The 50% probability of getting a tails is not a guarantee. It's possible to get more heads than tails, or vice versa. What the probability means is that on average the results are about equal, and you have an equal likelihood of getting either result. 

Mythbusters has an episode on this, actually. They explain it really well. I recommend you watch it.

Tricia made a circular mat from a square piece of cloth as shown in the diagram below.
kap26 [50]

The option C) 49 inches is the circumference of the circular mat.

<u>Step-by-step explanation:</u>

  • Tricia made a circular mat from a square piece of cloth.
  • The measure of the side length of the square = 14 inches.
  • The length of the side is same as the diameter of the circle.
  • Therefore, the diameter of the circular mat = 14 inches.

<u>To find radius :</u>

Radius = diameter / 2

⇒ 14/2

⇒ 7 inches.

<u>To find the circumference of the circular mat :</u>

Circumference = 2πr

where,

π has the default value of 3.14

r is the radius of the circular mat.

⇒ 2 × 3.14 × 7

⇒ 44 inches.

∴ The circumference of the circular mat is 44 inches.

Since, it is not given in the option. The option C) 49 inches which is close to 44 inches is the right option.

What is the answer to this question plss and thank you
cluponka [151]

A defines the function

f(1) = - 8 ×( \frac{5}{2} )^{0} = - 8 × 1 = -8

f(2) = - 8 ×( \frac{5}{2}) ^{1} = - \frac{(8.5)}{2}= - 20

f(3) = - 8 ×( \frac{5}{2}) ^{2} = - 8 × \frac{25}{4} = - 50

f(4)= - 8 ×( \frac{5}{2}) ^{3} = - 8 × \frac{125}{8} = -125

f(5) = - 8 ×( \frac{5}{2}) ^{4} = - 8 × \frac{625}{16} = - \frac{625}{2}
