Answer:

2

Step-by-step explanation:

Slope=Rise/Run

What does that mean? It means that the slope is equal to the change in y over the change in x.

It can be defined as m=(y1-y2)/(x1-x2)

Let's pick two random coordinates.

Say...

(30,10) and (40,30).

x1=30

x2=40

y1=10

y2=30

So when we plug those in, we get

m= (10-30)/(30-40)

which simplifies to (-20)/(-10)

which simplifies to 2.

Answer:

f(2) = 3

f(5/2) = 5

f(½) = -3

Step-by-step explanation:

Given the linear function f(x) = 4x - 5:

3 = 4x - 5

3 + 5 = 4x - 5 + 5

8 = 4x

8/4 = 4x/4

2 = x

Therefore, when f(x) = 3, x = 2.

5 = 4x - 5

5 + 5 = 4x - 5 + 5

10 = 4x

10/4 = 4x/4

5/2 = x

Therefore, when f(x) = 5, x = 5/2.

-3 = 4x - 5

-3 + 5 = 4x - 5 + 5

2 = 4x

2/4 = 4x/4

½ = x

Therefore, when f(x) = -3, x = ½.

Answer:

x = 128 degrees

Step-by-step explanation:

x and 52 make a linear pair, meaning they both equal 180 degrees.

Therefore, to solve x you can do:

x + 52 = 180

x = 180 - 52

x = 128 degrees

Answer:

here's the answer it's :

x=-28

y=-18

z=-16

Answer:

Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

If she has 3 pigs = she has 8 chickens

If she has 3(120) pigs = she has 8(120) chickens

If she as 360 pigs = she has 960 chickens

please give me a brainliest answer

Answer:It's an arithmetic sequence with a common difference, d, = 4

A1 = 8

A2 = 8+4 = 12

A3 = 12+4 = 16   = 8+4(3-1) = 8+4(2) = 8+8

AN = A1 + d(N-1)

AN = 8 +4(N-1)  =  the Nth term in the sequence

Answer:

if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.

We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.

Then draw a vertical line for your stem hopefully it is on lined paper.

single digits 1-9 go right side.

tenths get split keeping digits rights side

hundred units get split keeping tenth and single digits right side

and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.

Larger numbers that have 3 digits are more than double digits I've called 100th units

Numbers lower than 9 will be on rights side on the first line.

1-9  =  0 | 1  2 3 4 5 6 7 8 9

10-19   1 | 0 1 2 3 4 5 6 7 8 9

20-29  2| 0 1 2 3 4 5 6 7 8 9

100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line

We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.

Answer:

See Below

Step-by-step explanation:

Slope is rise over run.

Rise is the difference in the y values

Run is the difference in the x values.

Rise/Run = 5 (slope)

You have both x values 4 from one point and 5 from the other point so the difference is 1.  The Run is equal to 1

So you now have Rise / 1 = 5

The first y value you have is 5 and based on (rise/1 = 5), you know the difference in the y values must equal 5.  That means the other y value has to be either 10 or 0.

0 will not work because that would make the slope negative since the line would slope downward from left to right.

Answer:

Using a calculator, if you typed in 517 divided by 7, you'd get 73.8571. You could also express 517/7 as a mixed fraction: 73 6/7.

hey i am in k12 too can you help me

Step-by-step explanation:

Explanation:

*Based on what i know / understand*

Well one thing is that it is not E (the last choice because the mean is not the same as the median, they are different, the mean is 10.4 while the median is 13.4

And it can not be C or D because the mean is less than the median. So it is rather A or B.

But I think it is B.

Sorry if its wrong ;-;

Step-by-step explanation:

so (2,1)       (1,3)

     x1,y1      x2,y2

so then it would be

the slope is -1

so the equation is after using your x1 and y1 would be

y-1=-1(x-2)

and after you solve that by using the comunitive property, then it will look like

y-1=-1x+2

then you subtract 1 from the y side and make it

the answer is y=-1x+3

Answer:

The product is 240.

Step-by-step explanation:

The product is always when you multiply numbers together.

Answer:

Using 15 times table, we have 15 times 8 = 15 × 8 = 120. Hence, 15 times 8 is 120. b) First, we will write 15 times 7 minus 5 mathematically.

Table of 15 up to 20.

15 × 11 = 165 15 × 16 = 240

15 × 14 = 210 15 × 19 = 285

15 × 15 = 225 15 × 20 = 300

Step-by-step explanation: Hope this help!

Answer:

9/2 simplified

and 4 1/2 as a mixed number

Answer:

Fraction: 9/2

Mixed: 4 1/2

Step-by-step explanation:

We do this by first finding the greatest common factor of 90 and 20, which is 10.

Then, we divide both 90 and 20 by the greatest common factor to get the following simplified fraction:

9/2

Therefore, this equation is true:

90/20 = 9/2

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

9/2 = 4 1/2

Answer:

x = 4, y = -9/2 (-4.5)

Step-by-step explanation:

Using the second equation, we can divide both sides by -2 and get

y = 9/-2

y = -9/2

Then, we plug this y value into the first equation and get:

x + 4(-9/2) = -14

Simplify:

x - 18 = -14

x = 4

Answer:

On a coordinate plane, a vertical line goes through x = 3.

Step-by-step explanation:

I haven't looked at the other choices, but clearly this is a function

Answer:

will find at bottom

Step-by-step explanation:

A relation is a function of x if each value of x in the domain corresponds to exactly one value of y in the range. In other words, there should be no repeated values of x with different values of y.

Let's analyze each of the given tables to determine which one represents a function of x:

1. Table 1: In this table, we have x values of -1, 2, 2, and 3. Notice that x = 2 appears twice with different y values. This violates the definition of a function, so Table 1 is not a function of x.

2. Table 2: This table has x values of -8, -8, 1, and 1. Similar to the previous table, x = -8 and x = 1 appear twice with different y values. Therefore, Table 2 is not a function of x.

3. Table 3: In this table, all the x values are the same, which is -5. However, the corresponding y values are different (-9, 7, -9, and 2). Since each x value has a unique y value, Table 3 represents a function of x.

4. Table 4: This table consists of x values of -3, -2, 4, and 7. Each x value corresponds to a unique y value (-1, 5, 0, and -1). Therefore, Table 4 also represents a function of x.

To summarize, the relations that are functions of x are Table 3 and Table 4.

Step-by-step explanation:

slope intercept form y=mx+b

you just need to move the letters and numbers around to match this.

-4x-3y=-18

add 4x to both sides of the equal sign

-3y =4x-18

divide by negative 3 on both sides

y = -4/3x + 6

21. -2x+3y=21

add 2x to both sides

3y = 2x + 21

divide by 3 on both sides

y = 2/3x +7
