Answer:

x=1

Step-by-step explanation:

-6x + 4x= -2     original equation

-2x = -2    because you have to combine like terms ( -6x and 4x)

[tex]\frac{-2x}{-2} = \frac{-2}{-2}[/tex]  divide both sides by -2

Step-by-step explanation:

F(x) =x^2

G(x) =x-3

G(f(x))

= (x^2) -3

F(f(x))

= (x-3)^2

(x-3)(x-3)

x^2 -6x+9

For the second one

1/(x-3)

x-3 ≠ 0

x ≠ 3

Answer:

Step-by-step explanation:

This exercise desires to test our   knowledge of units conversion,

now, given that on the map 1 inch represents 4 miles

the distance of 1mile when converted to inches ordinarily would be

1mile is 63360 inches

since on the map

1 inch represents 4 miles

63360 inches represents  Xmiles

cross multiply we have

X would be = 63360*4

On a map one mile would be 253440 miles

Answer:

4 years

Step-by-step explanation:

This is a problem in simple interest:  i = prt, where:

p is the principal (intial amount), i is the interest, r is the annual interest rate and t is the time in years.

                                                    i

Solving i = prt for t, we get t = ------

                                                   pr

                                            $150

which comes out to t = ---------------------  =   4 years

Answer:

  squares of the reciprocals of natural numbers

Step-by-step explanation:

The numbers are squares of the reciprocals of successive natural numbers.

1 : (1/1)^2 = 1

2 : (1/2)^2 = 1/4

3 : (1/3)^2 = 1/9

4 : (1/4)^2 = 1/16

5 : (1/5)^2 = 1/25

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(6,7) and B(-5,-9)

The midpoint is

[tex]M = ( \frac{6 - 5}{2} \: , \: \frac{7 - 9}{2} ) \\ = ( \frac{1}{2} \: , \: - \frac{2}{2} )[/tex]

We have the final answer as

Step-by-step explanation:

The equation which is a radical equation from the given answer choices is; 7 √x = 14.

In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x: {\displaystyle r^{n}=x, } where n is a positive integer, sometimes called the degree of the root. A root of degree 2 is called a square root and a root of degree 3, a cube root.

here, we have,

According to the task content;

It follows that we are required to determine the equation which is a radical equation.

here, we have,

given that,

we have to find the radical equation.

now, we know that,

On this note, the required equation is 7 √x = 14 because the variable is under a radical.

#SPJ7

Answer:

0.17619

Step-by-step explanation:

We solve using z score formula

= z = (x-μ)/σ,

where x is the raw score = 5 accidents

μ is the population mean = 6.4 accidents

σ is the population standard deviation = 1.5

z = 5 - 6.4/1.5

= -1.4/1.5

= -0.93333

Approximately to 2 decimal places = -0.93

Determining the probability value from Z-Table:

P(x< 5) = P(z = -0.93) = 0.17619

Converting this to percentage =

The probability of weeks you would expect to have less than 5 accidents is

0.17619

We are asked in the question:

What proportion of weeks would you expect to have less than 5 accidents?

Proportion is also the same as:

Therefore, the proportion of weeks that you expect to have less than 5 accidents = 0.17619

17.62% of the accidents would be less than 5 accidents.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean,x=raw\ score,\sigma=standard\ deviation[/tex]

Given that μ = 6.4, σ = 1.5:

For x < 5 accidents:

[tex]z = \frac{5-6.4}{1.5}=-0.93[/tex]

From the normal distribution table, P(x < 5) = P(z < -0.93) = 0.1762 = 17.62%

17.62% of the accidents would be less than 5 accidents.

Answer:

-28/32,15/40,5/8,4.

The first thing you want to do is make the fractions improper . Then what you want to do next is add up the gallons of gas she used from her home to her grandparents' home and the gas she used from her grandparents' home to her cousins and you see what 21/5 + 41/10 is and you get 8.3 , So that's means she used 8.3 miles of gas and she has 15.3 gallons of gas left over because she started out with 23.3 miles .

Answer:

median = 10

mean = 10.9

Step-by-step explanation:

These are the answers because:

1) Whenever, there is an even set of numbers for the median, you have to take the two middle numbers in the number set given and then add them. After you add them, you have to divide them by 2.

In this case, it would be:

10 + 10 = 20

20/2 = 10

2) 10.9 is the answer for mean because first, you need to add all the numbers in the set. If you add

8 + 8 + 10 + 10 + 10 + 12 + 13 + 16 you would get 87. Then, you have to divide by how many numbers there are in the number set. In this case it would be 87/8 which is 10.875

Once you round it, you will get 10.9
