Solve the equation 1/2x -5+2/3x=7/6x+4

1/2x -5+2/3x =7/6x+4
First, you need to find the least <span>common </span>denominator between the 3 fractions....
2-3-6 The GCF is 6...
So to get rid of the fractions, multiply the whole equation by 2

6[ 1/2x -5+2/3x =7/6x +4 ]=
3x -30 +4x =7x +24

Now that we got rid of our fractions, we combine like terms...

3x -30 + 4x= 7x + 24
7x -30 = 7x + 24
-30 = 24 is not true

So, there is no solution

Hope this helps Nic
If you have seen this method in school before....
Maybe this will seem familiar
Good Luck!<span />

Answer:

D

Step-by-step explanation:

I have <u>no</u> idea how to explain this, but I'll try my best. Let me know if you want further clarification.

When you're slicing parallel to the base, it would mean "in line" with the base if that makes sense. If we were to draw a line on where we would slice it, and another repersenting the base, neither line would ever touch.

So looking through each possible answer, if we were to slice each shape parallel to the base, only D would produce a circle.

Again, sorry about this sloppy explaination.

wo crafty bacteria fall into a pot of milk which has recently been sterilized. They reproduce at a rate of 4% per day. Determine
RideAnS [48]

Answer:

Number of bacteria after 100 days is 1237.

Step-by-step explanation:

Since bacterial growth is a geometrical sequence.

Therefore, their population after time t will be represented by the expression

S_{n}=\frac{a(r^{n}-1)}{r-1}

Where a = first term of the sequence

r = common ratio of the sequence

n = duration or time

Since first term of the sequence = number of bacteria in the start = 1

Common ratio = r = (1 + 0.04) = 1.04

S_{100}=\frac{1[(1.04)^{100}-1)]}{1.04-1}

       = \frac{(50.5049-1)}{(0.04)}

       = 1237.64 ≈ 1237 [Since bacteria can't be in fractions]

Therefore, number of bacteria after 100 days is 1237.

Temka [501]
ANSWER

Phase shift: 2 units right.

EXPLANATION

The given sine function is

y = - \sin(x - 2)

In mathematics, a horizontal shift may also be referred to as the phase shift.

This function is shifted to the right 2 units.

I have one more question before im done so please help and have a good day.
3241004551 [841]

Answer:

  • See below

Step-by-step explanation:

<h3>Part A</h3>

<u>Solve the equation:</u>

  • 6x² + 48x + 120 = 0
  • x² + 8x + 20 = 0
  • x² + 8x + 16 + 4 = 0
  • (x + 4)² + 4 = 0
  • (x + 4)² = - 4

The left side is positive and right side is negative so no solution

<h3>Part B</h3>

There is no intercession with the x-axis, the graph of the function is entirely above the x-axis.

It means the diver won't reach the bottom of the lake
