30 kilograms of beans cost $5 how many beans can you buy for $1

Answer:

y-0 = [tex]\frac{4}{5}[/tex](x +2)

or

y - 4 = [tex]\frac{4}{5}[/tex](x -3)

These both mean the same thing.

Step-by-step explanation:

First, we have to find the slope.  The slope is the change in y over the change in x.

Our y's are 4 and 0 and your x's are 3 and -2

[tex]\frac{4-0}{3- - 2}[/tex]  = [tex]\frac{4-0}{3+2}[/tex] = [tex]\frac{4}{5}[/tex]

Now that we have the slope, we can use either point to write the eqation.

If we use point (-2,0)

The equation is

y - [tex]y_{1}[/tex] == m(x -[tex]x_{1}[/tex]

y - 0 = [tex]\frac{4}{5}[/tex] (x  - -2)

y - 0 = [tex]\frac{4}{5}[/tex](x +2)

If we use the point (3,4)

y-4 = [tex]\frac{4}{5}[/tex](x -3)

Based on the distance that Pacman traveled for every 6 seconds, and the distance being proportional to time, the Constant of Proportionality is 3.

The Constant of Proportionality shows how the quantity of a variable increases of decreases as the quantity of another related variable increases or decreases as well.

In the distance traveled by Pacman, the constant of proportionality can be found by the formula:

= Distance traveled / Time traveled

= 18 feet / 6 seconds

= 3 feet per second

The area of the given triangle in the diagram is 11.83[tex]cm^{2}[/tex]

Given triangle ABC. Let AB=x, BC=y, CA=z

We use Heron's formula when asked to find the area of a triangle and the measures of the sides are given only. According to Heron's formula,

Area of a triangle[tex]=\sqrt{s(s-x)(s-y)(s-z)}[/tex]   where s is the semi-perimeter of the triangle given by [tex]s=\frac{x+y+z}{2}[/tex] and x,y,z are the measures of the three sides of the triangle

According to the diagram of the triangle AB=x=8 cm, BC=y=3 cm,

CA= z= 9 cm

∴Semi-perimeter  [tex]s=\frac{8+3+9}{2}=10 cm[/tex]

∴Area of the triangle[tex]=\sqrt{10(10-8)(10-3)(10-9)}=\sqrt{10*2*7*1}=2\sqrt{35}=11.83 cm^{2}[/tex]

Therefore the area of the triangle ABC is 11.83[tex]cm^{2}[/tex]

Step-by-step explanation:

it is very similar to do the manual division of numbers.

5x² - 18x - 15 ÷ x - 4 =

so, we are starting on the left, dividing 5x² by x.

5x²/x = 5x

5x² - 18x - 15 ÷ x - 4 = 5x

then we multiply (x - 4) by 5x and subtract the result from the left part. and then we pull down the next term

5x² - 18x - 15 ÷ x - 4 = 5x

- 5x² -20x

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

0 2x - 15

and again, we take the left term and divide by x :

2x/x = 2

5x² - 18x - 15 ÷ x - 4 = 5x + 2

and again we multiply (x - 4) by 2 and subtract the result. and, if there still is one, we pull down the next term.

5x² - 18x - 15 ÷ x - 4 = 5x + 2

- 5x² -20x

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

0 2x - 15

- 2x - 8

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

0 -7

there is no more term to pull down, so we are finished.

there is a remainder in the last line unequal to 0.

this becomes therefore -7/(x - 4).

so, the total result is

(5x² - 18x - 15) ÷ (x - 4) = 5x + 2 - 7/(x - 4)

2.

the same thing. we are now dividing the left terms by 3x, and then multiply that result every time with (3x - 2), subtract this abd pull the next term down until there is no more term to be pulled.

6x³ - 16x² + 17x - 6 ÷ 3x - 2 = 2x² - 4x + 3

- 6x³ - 4x²

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

0 -12x² + 17x

- -12x² + 8x

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

0 9x - 6

- 9x - 6

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

0 0

there is no remainder in the last line, so the result is

(6x³ - 16x² + 17x - 6) ÷ (3x - 2) = 2x² - 4x + 3

The slope of equation is -80 and the equation of a line is y=-80x+800.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Given that, a large water tank holds 800 gallons of water.

From the table, we have (0, 800) and (1, 720)

Here, slope m=(720-800)/(1-0)

m= -80

Substitute m=-80 and (x, y)=(0, 800) in y=mx+c, we get

800=-80(0)+c

c=800

Substitute m=-80 and c=800 in y=mx+c, we get

y=-80x+800

Therefore, the slope of equation is -80 and the equation of a line is y=-80x+800.

Answer:

first choice in the image.

numerator: 12

denominator: 30

Step-by-step explanation:

"Name the numerator and denominator of the fraction that represents the number of trucks that he has loaded out of the total needing to be loaded"

so numerator = "number of trucks that he has loaded"

and denominator = "total needing to be loaded"

Joaquin was asked to load 30 trucks today. So his/her total would be 30.

thus the denominator is 30.

Joaquin has finished loading 12 already, which means he/she has loaded 12. so, the numerator is 12.

Step-by-step explanation:

To find the slope, m, you use the equation:

[tex]m \: = \frac{y2 - y1}{x2 - x1} [/tex]

From our question, (x1 = 7, y1 = 5) ; ( x2 = 2, y2 = -5)

Step-by-step explanation:

The rectangle MATH is translated by using the transformation rule P'(x, y) = (x - 7, y - 4) to create the rectangle M'A'T'H'.

In this problem we have the case of a rectangle, a geometric locus, that is translated both horizontally (7 units to the left) and vertically (4 units down). Vectorially speaking, a translation is represented by the following vector sum:

P'(x, y) = P(x, y) + T(x, y)     (1)

Where:

If we know that P(x, y) = (x, y) and T(x, y) = (- 7, - 4), then the transformation rule is derived below:

P'(x, y) = (x, y) + (- 7, - 4)

P'(x, y) = (x - 7, y - 4)

The rectangle MATH is translated by making use the transformation rule P'(x, y) = (x - 7, y - 4).

Relationship between the number of tokens Erin uses, x, and the number of pitches thrown by the pitching machine, y. x (tokens) y (pitches) 1 14 2 28 3 42 7 98

by, observing the given data we say that;

x is proportional to y so, the general equation is given by

x ∝ y so, by removing the proportionality sign we get y=k*x;

now using given x and y we put in this equation to get the value of k; then by substituting the value of k in this equation we get our required equation.

so, putting x=1 and y=14 we get k=14;

and, putting x=2 and y=28 we get k=14;

and putting x=3 and y =42 we get k=14;

similarly, the last data satisfy the equation.

By putting k =14 in the equation we get, Y=14*X

thus, Y=14*X is our required answer.

Answer:

-4 -1 1 3.9 3.99

Step-by-step explanation:

The number can be anything that is less than the number 4.

Hope this helps! :)

The values which satisfy the inequality y < 4 are - 4, - 1, 1, 3, 3.9. 3.99, 3.999.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

An inequality y < 4 is given.

This states that the variable y is strictly less than 4 it could be 3.999999.. but not 4.

Then the value that makes the inequality true are,

- 4, - 1, 1, 3, 3.9. 3.99, 3.999,

If the inequality was y ≤ 4 then 4 could have included 4 only but not 4.001.
