Answer:

The distance between these two points with coordinates (-1, -4) and (-9, -8) is 8.94 unites

Answer:

(2,-1)

Step-by-step explanation:

Given system of equations:

We are going to use the substitution method.

Step 1: Solve for x = y + 3 for x:
(Substitute y + 3 for x in 3x + 2y = 4)

3x+2y=4

3(y+3)+2y=4

5y + 9 = 4 ----> Simplify both sides of the equation

5y+9+−9=4+−9  -------> Add -9 to both sides

5y=−5

5y5 = -5/5  ------> Divide both sides by 5

y = −1

Step 1: Substitute -1 for y in x = y + 3:

x = y + 3

x = -1 + 3

x = 2 --------> (Simplify both sides of the equation)

Answer:

(2,-1)

Answer:

12

Step-by-step explanation:

36 / (x - 3) = 4

multiply both sides by (x - 3):

(x - 3)(36 / (x - 3)) = 4(x - 3)

36 = 4(x - 3)

expand right side:

36 = 4x - 12

add 12 to both sides:

36 + 12 = 4x - 12 + 12

48 = 4x

divide both sides by 4:

48/4 = 4x/4

x = 12

Option D. The statement that is true from the equations that we have here is D. The equation x3 - x2 - x + 1 = 0 is equivalent to the equation x2(x - 1)-(x-1)=0.

I will have to start for the equation D, because at close glance we can easily see that the powers would be equal

The equation x3 - x2 - x + 1 = 0 is equivalent to the equation x2(x - 1)-(x-1)=0.

We are to simplify x²(x - 1)-(x-1)

we would have to open the brackets from the above

 x² * x +  x² * (-1) - x - (-1) = 0

It would be important to pay attention at the signs

such that we would have

x³ -  x² - x + 1 = 0

Therefore the equation  x^3 - x^2 - x + 1 = 0 is equivalent or equal to  x³ -  x² - x + 1 = 0 because they have the same solution

Answer: Jorge would have to run 3 [tex]\frac{3}{8}[/tex] miles to reach his 23 mile goal.

Step-by-step explanation:

When you add 5 [tex]\frac{3}{4}+ 7 \frac{3}{8}[/tex]=[tex]13\frac{1}{8}[/tex]

[tex]13\frac{1}{8}+6 \frac{1}{2}=19\frac{5}{8}[/tex]

Now you can subtract [tex]19 \frac{5}{8}[/tex] from 23, which would give you [tex]3\frac{3}{8}[/tex], being the total amount of miles left to run. You can add the terms without a calculator as well, by making the fractions have a common denominator.

a) 7y and (2y²-9) are the length and width expressions where one dimension is the GCF.

b) When y= 2, the area of the rectangle is -14

The area amount expresses the size of a region on a planar or curved surface.

A two-dimensional figure's area is the amount of space it occupies. It is the number of unit squares that cover the surface of a closed figure in other words. Square units, which are frequently expressed as square inches, square feet, and so on, are the standard unit of area.

A rectangle is a two-dimensional figure, and if one of the dimensions is the GCF, as indicated in the job, then:

7y and (2y²-9) are the length and width expressions where one dimension is the GCF.

Furthermore, when y= 2, the area of the rectangle is;

The number of men and women that work at the company are;

Number of men = 36

Number of women = 18

Let the total number of employees in the company be x.

Now, we are told that 75% of the employees were men. Thus;

Number of men = 75% * x = 0.75x

Number of women = 0.25x

Now, we are told that after 6 women joined, the ratio of men to women became 2: 1.

Thus;

New total employees = x + 6

New total number of women = 0.25x + 6

Thus;

0.75x/(0.25x + 6) = 2/1

Cross multiply to get;

0.75x = 2(0.25x + 6)

0.75x = 0.5x + 12

0.75x - 0.5x = 12

0.25x = 12

x = 12/0.25

x = 48

Number of women = 0.25(48) + 6 = 18

Number of men = (48 + 6) - 18 = 36

Dan is 12 years old.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the Age of Dan is x years

Answer:

Step-by-step explanation:

f(x) = |x|

This absolute value will have a v shape, the "v" point at (0,0)

Next,

f(x) = |x-1|

This (-1) moves the v shape one unit to the right, "a translation to the right by 1."

Finally,

f(x) = |x-1| - 3

This (-3) moves the v shape down 3 units. This is why the answer is the original

f(x) = |x|

except it's moved right by 1, and down by 3.

Step-by-step explanation:

The graph that represents is translated right by 1 units and 3 unit up to form. Hence, graph (a) is correct.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

The parent function of an absolute function is;

y = |x|

When a function is translated right by h units, the transformation rule by;

y = |x-h|

So:

|x-1|-3 means that it is translated right by 1 units

When a function is translated up k units, then the transformation rule is:

y = |x| + k

y = |x-1|-3

This means that it is translated right by 1 units and 3 unit up to form

Hence, graph (a) is correct

Answer:

x = 1/2

y = 4

Step-by-step explanation:

2x + 3y = 13 ----------------------(1)

4x - y = -2  ------------------------(2)

Multiply Eq. (1) by 2

2(2x + 3y) = 13 × 2

4x + 6y = 26 -------------------(3)

Subtract Eq. (3) from Eq. (2)

4x - y - 4x - 6y = -2 - 26

-y - 6y = -28

-7y = -28

7y = 28

Divide 7 to both sides

Put y = 4 in Eq. (2)

4x - 4 = -2

Add 4 to both sides

4x = -2 + 4

4x = 2

Divide 4 to both sides

To describe the temperatures for the week, we can apply the following statistical tools:

a) Find the mean, median, mode, and range.

c) Construct a line graph.

d) Construct a stem and leaf plot.

We can describe temperatures using measures of central tendencies (especially the mean, median, and mode).

The mean temperature is the average, which shows the overall trend in temperature changes.  It is computed by adding up the temperatures for the period and diving by the number of data values.

In addition, the median gives the middle value when the data set is ordered in ascending or descending orders. Similarly, the mode gives the highest temperature occurrence within the period. It may not be useful here.

We can estimate the difference between the highest and lowest temperature for the week with the range.

A line graph (showing connecting lines) and a stem-and-leaf plot (like a bar graph) can graphically describe the temperatures for the week.

Thus, we can use Options A, C, and D to describe the temperature.

We will see that the functions are inverses by proving that the composition is equal to the identity.

Two functions are inverses if their composition is equal to the identity, this means that if h(t) and k(t) are inverses, then we can write:

h(k(t)) = t

and

k(h(t)) = t

Proving one of these will be enough.

Here the functions are:

h(t) = (3t + 5)/t

k(t) = 5/(t - 3)

Let's find h(k(t))

We will get:

h(k(t)) = (3*k(t) + 5)/k(t)

Now we can replace the function k(t) there.

h(k(t)) = (3*5/(t - 3) + 5)/(5/(t - 3))

Now we can simplify this using algebra.

h(k(t)) = ( 15/(t - 3) + 5)*(t - 3)/5

h(k(t)) = (15/(t - 3))*(t - 3)/5 + 5*(t - 3)/5

h(k(t)) = 3 + (t - 3) = t

h(k(t)) = t
