simplify the expression
xy + 4x – 3xy – x

Answer:

X = 1 ; x = 7

Step-by-step explanation:

Given the equation:

s=10|x-4|+50

s = sound level in decibels ; x = number of measures of music played

Take away 50 from Both right hand and left hand side of the equation

Recall s = 80

80 - 50 = 10│x - 4│+ 50 - 50

30 = 10│x - 4│

To get rid of the absolute value sign, append ± to left hand side

± 30 = 10x - 40

Minimum value of x : - 30 + 40 = 10x ; 10 = 10x ; x = 1

Maximum value of x : 30 + 40 = 10x ; 70 = 10x ; x = 7

Answer:

-2

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 17 - -11)/( -9 -5)

    = ( 17 +11)/( -9 -5)

    28/-14

  = -2

Answer: -2

Step-by-step explanation:

X=-9-5=-14

Y=17 - - 11=28

28/-14=-2

Answer:

Step-by-step explanation:

Let X be the normal distribution

Kindly find attached a detailed annotation of the solution to the problem.

in the attached document, we found the value that corresponds to  80th percentile, hence we found the value such that the probability that the variable x is lower than this value is 0.8.

Also, from the calculation, we found that the value which corresponds to the 80th percentile is $1945

Answer:

$84

Step-by-step explanation:

This is a super simple question. All you have to know is how much money will be charged a month, and how many months there are in a year. Just simply multiply 7 by 12 as the streaming service is charging 7 dollars a month and there are 12 months in a year. After you multiply the two numbers, you should end up with 84 dollars charged after 1 year.

Answer:

there is no way that is an actual question

Answer:

105 free throws made if Asia shoots 150

Step-by-step explanation:

Find the percentage form of 14 out of 20

14 / 20 = 0.7 (70%)

Then calculate 70% of 150:

0.7 multiplied by 150 = 105

(Can check by doing 105 / 150 = 0.7)

Asia will make 1058 free throws out of a total of 150 shoots.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that,

Asia makes 14 out of 20 free throws

Percentage free throws = free throws/total  × 100

Percentage free throws = 14/20 × 100

Percentage of free throws = 70%

Now,

If Asia throws 150 then with the same proportion she will again make 70% of her throw free.

So,

70% of 150 = 150 × 70/100 = 105

Hence "Asia will make 1058 free throws out of a total of 150 shoots".

Step-by-step explanation:

Answer:

x = 0

Step-by-step explanation:

First, distribute the -2 to the parentheses:

-14 - 8x = -2(-3x + 7)

-14 - 8x = 6x - 14

Add 14 to both sides:

-8x = 6x

Subtract 6x from both sides:

-14x = 0

Divide each side by -14:

x = 0

So, x = 0

Answer:

0

Step-by-step explanation:

-14-8x=6x-14(cancel equal terms)

-8x=6x(move the variable to the left)

-8x-6x=0(collect like terms)

-14x=0Divide both sides)

x=0

Answer:

Kindly check explanation

Step-by-step explanation:

Length of parking lot = 20 feets

Speed of tortoise which starts at the edge = 6 feets per minute

Speed of tortoise which starts 4 feets from the edge = 2 feets per minute

Equation to represent when they will be in the same spot.

Distance = speed * time

Distance of Tortoise at edge = 6ft/min * t = 6t - - (1)

Distance of the other tortoise = (4 + 2t) - - - (2)

Equating both (1) and (2)

6t = 4 + 2t

6t - 2t = 4

4t = 4

t = 4/4

t = 1

Hence, they'll be at the same spot after 1 minute.

Answer:

She will never complete 1 foot

Steps:

1) We will find the maximum value of this process, when this is carried out infinite times.

This process goes like a Infinite GP, whose

First term,a = 1/2ft.

Common Ratio, r = 1/2ft.

Maximum value of this process is One Foot when the athlete jumps forever or Practically, she will never complete her 1 foot.

Hence, Athlete will never complete. her complete .

Starting from 1/2 ft. ,and ending at 1 foot.

The value always tends toward 1 but never reaches one.

Answer:

m∠PQR = (7x + 6)⁰

Step-by-step explanation:

Please find the diagram in the attachment.

Mathematically, since the angle PQR is bisected by the given line, it means that;

RQS + PQS = PQR

Thus;

PQR = (2x + 6) + 5x

PQR = 2x + 6 + 5x

PQR = 7x + 6

m∠PQR = (7x + 6)⁰

Simplify the equation by using cross-multiplication

4y=36

Divide both sides of the equation by 4

y=9

If this helped, please rank me brainliest! :)

Answer:

Y would be 9

Step-by-step explanation:

If the x is 12 and it shows the simplified version take the 4 and multiply it by how much you would need which is 3 so you go to the 3 above 4 and multiply it by 3 and you will get 9/12

Answer:

(-4,-0.5)

Step-by-step explanation:

midpoint = ((x1+x2)/2, (y1+y2)/2)

               = ((-5+-3)/2, (-4+3)/2)

               = (-8/2, -1/2)

               = (-4,-0.5)

Answer:

To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.

Answer:

No

Step-by-step explanation:

Assume that it is a right triangle for now

According to the Pythagorean Theorem...

(38)^2 + (56)^2 = (69)^2

4580 ≠ 4761

Both sides are not equal, and hence the Pythagorean Theorem can't be applied to the triangle. It is not a right triangle.

Answer:

Reduce the expression, if possible, by cancelling the common factors.

Scientific Notation:

Hi!

Lets go through this together.

Using the operation, PEMDAS, we start from left, then go to right.

since there are two pairs of parenthesis, we start with the one on the left.

(6x10^2)

so now, we do the exponent, 10^2

10x10= 100

So our answer for this part is 100.

Now we have (6x100)

6x100=600

So now, the equation is 600÷(3x10^-3)

Now, we do the parenthesis on the right.

(3x10^-3)

First, we do the exponent, 10^-3

10x-10x-10= 1,000

so now, the equation is (3x1,000)

Now, we multiply.

3x1,000=3,000

So now, the equation is 600 ÷ 3,000

600 ÷ 3,000 = 0.2

So, your answer is 0.2.

__________________________________________________________

(6 x 10^2) ÷ (3 x 10^-3)

=(6 x 100) ÷ (3 x 10^-3)

= 600 ÷ (3 x 10^-3)

= 600 ÷ (3 x 1,000)

= 600 ÷ 3,000

= 0.2

(also, the scientific notation is 2x10^2)
