What is the domain of the following relation?
{(-3, 3), (1, 1), (0, -2), (1, -4), (5, -1)}
​

Answer:

Step-by-step explanation:

Slope of perpendicular lines = -1

y = 5/2x + 3

[tex]m_{1}=\frac{5}{2}\\\\m_{1}*m_{2}=-1\\\\[/tex]

        [tex]m_{2}=[/tex] -1 ÷ [tex]m_{1}[/tex]

               = [tex]-1*\frac{2}{5}=\frac{-2}{5}[/tex]

(-3 , -5)

Equation of the required line: y - y₁ = m(x -x₁)

                                                y - [5] = [tex]\frac{-2}{5}(x - [-3])\\[/tex]

                                               [tex]y+5=\frac{-2}{5}x + 3*\frac{-2}{5}\\\\y+5=\frac{-2}{5}x-\frac{6}{5}\\\\ y =\frac{-2}{5}x-\frac{6}{5}-5\\\\ y = \frac{-2}{5}x-\frac{6}{5}-\frac{5*5}{1*5}\\\\ y = \frac{-2}{5}x-\frac{6}{5}-\frac{25}{5}\\\\\\ y=\frac{-2}{5}x-\frac{31}{5}[/tex]

Explanation:

Think of "eighths" as the name of a coin type.

The fraction 5/8 means "5 eighths" which we can think of as "5 coins".

Similarly, 1/8 can be thought of as "1 coin" because of 1 in the numerator.

We have two coins of the same type (both "eighths") which means we can combine the coin counts to get 5+1 = 6 coins total.

In other words, 1/8 + 5/8 = (1+5)/8 = 6/8

This is why we add the numerators but keep the denominators the same. If the denominators were different, then we cannot combine the fractions until we get them to the same denominator (such as the LCD).

Having different denominators is like adding apples to oranges. Unless we can somehow get them to the same unit, then adding wouldn't make much sense.

---------------------------

After adding, we need to reduce the result.

The numbers 6 and 8 have the common factor 2.

Divide each by this common factor.

You can write it like this if you wanted:

[tex]\frac{6}{8} = \frac{6 \div 2}{8 \div 2} = \frac{3}{4}[/tex]

Or in short,

[tex]\frac{6}{8} = \frac{3}{4}[/tex]

If you cut a pizza into 8 slices, and eat 6 of them, then it's the same as eating 3 out of 4 total slices. That's one visual way to represent the fraction 6/8 turning into 3/4.

Explanation:

The angles marked with a single arc are one pair of congruent angles forming one "A" of "ASA".

The other "A" is the angles marked with double arcs.

The "S" refers to the sides between those said angles. These sides overlap perfectly so we have a shared side, meaning they must be the same length (refer to the reflexive property).

This is why the triangles are congruent by the ASA (angle side angle) congruence theorem. One triangle is a reflected version of the other. The mirror line being that shared overlapping side. Congruent triangles are like twin identical copies.

Answer:

1/6

Step-by-step explanation:

There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.

Answer:

1/6

Step-by-step explanation:

There are 4 possible primes: 2, 3, 5, 7

First card has 4/9 probability of being a prime. Second card has 3/8 probability of being a prime(since 3 prime cards left and 8 total cards left because we do not replace the first card). 4/9 * 3/8 = 1/6.

Another way to do this is using combinatorics. C(9,2) = 36 ways to choose 2 distinct cards, C(4,2) = 6 ways to choose two of the "prime" cards. 6/36 = 1/6.

Answer:

the first : all real numbers

Step-by-step explanation:

the domain is the interval or set of all valid values for x.

reflecting the graph over the x-axis simply means to multiply the original function by -1.

that does not change the domain in any case. it only changes the range (the interval or set of possible y values).

so, the domain is the same as for the original function : all real numbers.

Answer:

y=[tex]\frac{1}{2}[/tex]x-8

Step-by-step explanation:

To solve this, you have to use the formula [tex]\frac{x_{2} -x_{1} }{y_{2} -y_{1}}[/tex] to find the slope.

[tex]\frac{0+4}{-8-0}[/tex] = 4/-8 = -1/2

so the slope is -1/2

Now, you plug your values into the formula y=mx+b

m = slope = 1/2

b = y-intercept = -8

so the final formula is y=[tex]\frac{1}{2}[/tex]x-8

First, we need to find how many books there are in each group;

If we look at group 1, they have 18 books.

If we look at group 4, they have 9 books. (We got this because they have 6 whole books, and they have half of a those 6 books which is 3 books in the other book symbol, so combined: 6 + 3 = 9)

18(group 1) - 9(group 4) = 9, group 1 read 9 more books.

Answer:

w=67°

Step-by-step explanation:

[tex](-3, 5)[/tex]

Step-by-step explanation:

Isolate x from the first equation:

[tex]x=\frac{11-4y}{3}[/tex]

Now, substitute it in  the second equation:

[tex]\begin{bmatrix}2\cdot \frac{11-4y}{3}+y=-1\end{bmatrix}[/tex]

This gives you:

[tex]\begin{bmatrix}\frac{22-5y}{3}=-1\end{bmatrix}[/tex]

So, you conclude: y = 5

Next, we substitute y = 5 into [tex]x=\frac{11-4y}{3}[/tex]

So, we get:

[tex]x=\frac{11-4\cdot \:5}{3}[/tex]

Then:

[tex]x=-3[/tex]

Answer:

so graph your first point. (x=2, y=1)

Step-by-step explanation:

Your 5/3 is your rise over run. So go up 5 from 2 you should be at 7 and over 3 from your 1  so your next point would be (x=7, y=4) now get a ruler and connect your two points. make sure to use a ruler to make your line straight.  

To graph a line with a slope of 5/3 and passes through the point (2, 1), we can use the slope-intercept form of a linear equation, which is given by:

y = mx + b

where:

- y and x are the coordinates of any point on the line

- m is the slope of the line

- b is the y-intercept (the point where the line crosses the y-axis)

Given the slope (m = 5/3) and the point (2, 1), we can substitute these values into the equation and solve for the y-intercept (b):

1 = (5/3)(2) + b

1 = 10/3 + b

To isolate b, we subtract 10/3 from both sides:

1 - 10/3 = b

-7/3 = b

Now we have the values of m and b, so we can write the equation of the line:

y = (5/3)x - 7/3

To graph the line, we plot the y-intercept at (0, -7/3), and then use the slope (5/3) to find additional points on the line.

Since the slope is positive, we can move up 5 units vertically and 3 units horizontally from the y-intercept to find another point. We repeat this process to find more points if needed.

Thus, using this, one can plot the graph.

Answer:

x/8

Step-by-step explanation:

how I see the problem I just put the 1 over the 8 because you can't really do anything else with the problem

The inverse f'^{-1}x of the given function is x/8

Given the function y = 8x, we are to find the inverse of the function.

Replace y with x

x = 8y

Make y the subject of the formula

x = 8y

Divide both sides by 8\

x/8 = 8y/8

x/8 = y

Swap sides

y = x/8

Hence the inverse f'^{-1}x of the given function is x/8

An Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]

Step-by-step explanation:

Beginning balance of Jennifer=$4750

Now she deposits a paycheck = p

So, New balance = 4750+p

Now she writes a check = c

Remaining balance = 4750+p-c

Now she writes a check = d

Remaining balance = 4750+p-c-d
