Answer:

choice 1) x = 2

Step-by-step explanation:

7x-6 = 12-2x    because point B is in the middle of AC

reduce:

add 2x to each side:

9x-6 = 12

add 6 to each side:

9x = 18

divide both sides by 9:

x = 2

Answer:

[tex]T < -4.2[/tex]

Step-by-step explanation:

Given

[tex]Monday =2.9F[/tex]

[tex]Tuesday = -4.2F[/tex]

Required

Which is lesser than both temperatures

I will answer on general terms, since no option were given.

For a temperature to be lesser than both temperatures, it has to be lesser than -4.2F because: -4/2F < 2.9

Let T be the temperature less than both, the inequality is:

[tex]T < -4.2[/tex]

So, the values of T can be -5,, -4.5 and so on.

Step-by-step explanation:

Me + The upcoming championship high school football game is a big deal in your little town. The problem is, it is being played in the next biggest town, which is two hours away! To get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. You determine that if more than three students share a ride, on average, you will create the app.

You conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. The following data are collected:

6 5 5 5 3 2 3 6 2 2

5 4 3 3 4 2 5 3 4 5

You and your partner will construct a 90% confidence interval and 95% confidence interval for the mean number of students who share a ride to school, then you will compare and interpret the results.

Part A: Decide which partner will construct each confidence interval, and then state the parameter and check the conditions.

Part B: Construct the confidence interval. Be sure to show all your work, including the degrees of freedom, critical value, sample statistics, and an explanation of your process.

Part C: Interpret the meaning of the confidence interval, and describe the difference in the width of the interval and the margin of error.

Part D: Use your findings to explain whether you should develop the ride-share app for the football game. = My brain hurts!!!

Step-by-step explanation:

if you reflect a shape over the y axis all the numbers stay the same. The only thing that changes is the sign of the x values

so all of the values were positive in the preimage but now they're positive if that makes sense

Step-by-step explanation:

1. making the equation:

shoes = x

shirts = y

175 = x + 3y

x = 4y

2. graph it (I'm using desmos)

the green line is for 175 = x + 3y and the purple one is for x = 4y

3. find the price

x = 4y

175 = 4y + 3y

175 = 7y

y = 175/7 = $25

price of the shirt = $25

x = 4y = 4*25 = $100

price of a pair of shoes = $100

The question was incomplete. Below you will find the missing image.

Option 2 is correct. i.e. x = 1

The given logarithmic equation is

[tex]log_{2}(x)+ log_{2}(x+7)=3[/tex]

⇒ [tex]log_{2}[x(x+7]=3[/tex]          [∵[tex]loga+logb=log ab[/tex]]

⇒ [tex]x(x+7)=2^{3}[/tex]

⇒ [tex]x^{2} +7x-8=0[/tex]

⇒ [tex](x+8)(x-1)=0[/tex]

⇒ x = -8, 1

At, x = 1

[tex]log_{2}(1)+ log_{2}(1+7)=3[/tex]

⇒ 0+3=3

⇒ 3=3

L.H.S = R.H.S, therefore x=1  is a solution of the given equation.

At, x = -8

[tex]log_{2}(-8)+ log_{2}(-8+7)=3[/tex]

⇒ [tex]log_{2}(-8)+ log_{2}(-1)=3[/tex]

Logarithmic functions are defined only for positive values.

So, x = -8 is not a solution of the given equation, i.e. a extraneous solution.

Hence, x= 1 is the only solution of the given equation.

Step-by-step explanation:

Step-by-step explanation:

First, I decided to determine the vertical asymptote! You can determine the vertical asymptote by taking the denominator and setting it equal to zero.

−4x+4=0

−4x=−4

x=1

There's a vertical asymptote at x=1.

Now for the horizontal asymptote! The horizontal asymptote is determined by looking at the leading coefficients in the numerator and denominator. Here's a helpful visual.

content://com.cryptotab.android.FileProvider/images/screenshot/16159519510813476709092178134526.jp

In our case, the leading coefficient in the numerator (x2) is larger than the leading coefficient in the denominator (−4x). This means there is no horizontal asymptote!

In some cases, a slant asymptote may be present in a graph. These are sometimes present in graphs that have a stronger leading coefficient in the numerator than the denominator. To determine the slant asymptote, we need to divide the numerator by the denominator.

content://com.cryptotab.android.FileProvider/images/screenshot/16159520052041557972364765603410

The slant asymptote is y=−x4−1

Holes are determined by finding numbers that when plugged into x, return undefined. On a graphing calculator these values will give us an error. Luckily for us, there are no holes, so we can move on.

X-intercepts are values that make the numerator equal zero. We can find these by setting the numerator equal to zero and solving.

x2+3x=0

x(x+3)=0

x+3=0

x=−3

Another number that makes the numerator equal zero is, well, zero!

x2+3x=0

(0)2+3(0)=0

0=0

So we know our x-intercepts are 0 and -3.

To find the y-intercepts, set x equal to zero and solve the equation!

y=x2+3x−4x+4

y=(0)2+3(0)−4(0)+4

y=04

y=0

So we have a y-intercept at y=0!

A living room floor consists of an area rug and hardwood. The area of the rug is 182 square feet. How many square feet is the entire living room?

pls help :(

Answer:

A

Step-by-step explanation:

its hard to explain but pretty much if you didn't know the ^x+1 is the x intercept except when its graphed its no marked at (1,0) its mark ate (-1,0) because it always takes the inverse

if you go over to the right 3 then your adding 3 to the x intercept or subtracting 3 from ^x+1 so it would be ^x-2

the y intercept part is easy all you have to do is subtract 2 from the y intercept so it would be +2

hope this helps :D

The vertical asymptotes are x= 0 and x = -1 option (D) and option (F) are correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

F(x) = (x-5)/3x(x+ 1)

To find the vertical asymptotes:

3x = 0

or

x = 0

x + 1 = 0

or

x = -1

Thus, the vertical asymptotes are x= 0 and x = -1 option (D) and option (F) are correct.

Answer:

The correct solution is "x = -5 and x = -8".

Step-by-step explanation:

The given equation is:

⇒ [tex]x^2+13x+40=0[/tex]

On factorizing the above equation, we get

⇒ [tex]x^2+5x+8x+40=0[/tex]

On taking "x" common, we get

⇒ [tex]x(x+5)+8(x+5)=0[/tex]

⇒         [tex](x+5)(x+8)=0[/tex]

Now,

⇒                       [tex]x+5=0[/tex]

On subtracting "5" from both sides, we get

⇒                 [tex]x+5-5=0-5[/tex]  

⇒                             [tex]x=-5[/tex]

Or,

⇒                        [tex]x+8=0[/tex]

On subtracting "8" from both sides, we get

⇒                  [tex]x+8-8=0-8[/tex]

⇒                              [tex]x=-8[/tex]

Answer:

Step-by-step explanation:

its c for sure i got it right on a test

The value of y is -8.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

From the graph,

Two coordinates are (-2, 0) and (2, -2)

m = (-2 - 0) / (2 + 2) = -2/4 = -1/2

Now,

The equation of a line is y = mx + c.

(-2, 0) = (x, y)

y = mx + c

0 = (-1/2)(-2) + c

0 = 1 + c

c = -1

Now,

y = (-1/2)x - 1

Substitute x = 14.

y = (-1/2) x 14 - 1

y = -7 - 1

y = -8

Thus,

The value of y is -8.

Mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.

Mean is the sum of numbers divided by the numbers. It is also known as average.

Fow calculating mean we have to find sum of  numbers which is calculated in figure as 1553.

Mean=1553/25=62.12

Mode is basically the number having higher frequency which is 53.

Median is[ (n+1/2)th term,(n/2)th term]/2

=(60+60)/2

= 60.

Range is basically the difference of smallest number and largest number divided by 2=82-49=32

Q3=3(N+1)/2

=3(25+1)/2

=18.5th term which is 69.
