solve the inequality

Answers

Answer:

x > 6

Step-by-step explanation:

-2x < -12

divide by -2

switch signs because you're dividing by a negative number

-2x/-2 < -12/-2

x > 6

Hope this helps :)

Answer:

x > 6

Step-by-step explanation:

Solve -2x <-12 for x.  Your answer must be a set of real numbers.

Divide both sides by -2.  Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:

-2x < - 12

-----   ------

 -2      -2

This becomes x > 6, "the solution set"

Elastic energy, such as a stretched archery bow is not an example of kinetic energy.

What is Energy?

Energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.

Energy are of two types:

Potential Energy

Kinetic energy

potential energy, stored energy that depends upon the relative position of various parts of a system

Kinetic energy is the energy an object has because of its motion.

In the given options,  Elastic energy, such as a stretched archery bow is not an example of the kinetic energy. because a stretched bow is potential energy because the arrow is not moving but stretched holding potential energy for it to be released to its target.

Answer:

  1) 2^9 = 512

  2) 2^(3t) = 2^6 for t=2

Step-by-step explanation:

1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...

  2^9

Using any of a variety of means, the value of this expression can be found to be ...

  2^9 = 512

__

2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:

  (2×2×2) × (2×2×2) × (2×2×2)

If this represents the number after 3 hours, then the number after 2 hours is expected to be ...

  (2×2×2) × (2×2×2) = 2^6

That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.

1. 2^9 = 512
2. as you can split up the fact in 3 hours it is 2^9 to find out one hour (divide by 3) which is 2^3 so we would just multiply it by 2 which equals 2^6

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.

Answer:

3.391 Gallons Per Minute

Step-by-step explanation:

78/23=3.391

Round 3.391 to 3.4

Answer:

≈3.39130434783 gallons per minute

Step-by-step explanation:

The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:

[tex]78 : 23[/tex]  OR  [tex]\frac{78}{23}[/tex]

We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:

[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]

And of course, if there's a need to round, go ahead.

And please do not waste water!

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

Answers

112.5 seconds

First convert minutes to seconds so 7 x 60 + 30, that will get you the total seconds and should equal 450 secs. Divide that by 4: 450 / 4, equals 112.5 seconds

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.

A line passes through (2, 8) and (4, 12). Which equation best represents the line?
1. y = 1/2x + 6

2. y = 2x + 7

3. y = 2x + 4

4. y = 1/2x + 10

Answers

y=2x+4 because we’re moving up 2 units for every unit we move to the right, and if we plug 0 in for X we end up with the +4
I would say 3 (I am not completely positive, I am not that smart with graphs)

X: (2 + 4) / 2 Equals: 3
Y: (8 + 12) / 2 Equals: 10
Then multiple 3 by 2 get 6, add four, you get 10 which is equal to Y

Answers

The correct answer is B!

Answer:

The answer is B) a = -7/16

Step-by-step explanation:

3/4 + 4a/7 = 6a/7 + 7/8

By transposing, we get

=> 3/4 - 7/8 = 6a/7 - 4a/7

=> (by taking LCM) 6-7/8 = 6a-4a/7

=> -1/8 = 2a/7

=> -7 = 16a (by cross multiplication)

=> a = -7/16

Find the percent markup

A store advertises a 35% markdown on the PlayStation 5 gaming console. It normally sells for $1,019. what is the final sale price?

Answers

the final sale price would be $662.35
ANSWER: $662.35

EXPLANATION:

We know the how much the PS5 cost and we know the markdown percentage. So we need to find 35% of 1,019 because we need to know how much to take away.

35% of 1,019 = 356.65

So now we take the original price and subtract 356.65 from 1.019.

When we do this we get $662.35
