Answer:

y = 2x - 6 or y = 2/1x - 6

Step-by-step explanation:

Remember that the slope-intercept formula is y = mx + b. The "m" is always going to be the slope, and "b" is what the y-intercepts at. The slope could also be a fraction (meaning it rises up 2 and goes to the right 1). If you were to graph it using "2" as the slope, it would be done the same way.

During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the remaining apples. On the third hour he sold 25% of the remaining apples, and so on, selling 5% more each following hour. If during the third hour he sold 34 kg of apples, how many kilograms of apples did he have initially?

Answers

Answer:

75 kg

Step-by-step explanation:

$\sf2x+3y=-9$

Convert to slope-intercept form, y = mx + b.

$\sf2x+3y=-9$

Subtract 2x to both sides:

$\sf3y=-2x-9$

Divide 3 to both sides:

$\sf~y=-(2)/(3)x-3$

Now it's in slope intercept form, y = mx + b where 'm' is the slope. So the slope here is -2/3, which is Negative.

$\sf~y=3x-6$

This is already in slope intercept form. So the slope here is 3, which is Positive.

For #3 and #4, take any two points from the table and plug them into the slope formula.

$\sf~m=(y_2-y_1)/(x_2-x_1)$

Let's take (0, 7) and (1, 5).
x1 y1 x2 y2

$\sf~m=(5-7)/(1-0)$

Subtract:

$\sf~m=(-2)/(1)$

Divide:

$\sf~m=-2$

So the slope is negative.

For #4, let's take (2, -8) and (3, -7)
x1 y1 x2 y2

$\sf~m=(-7-(-8))/(3-2)$

Subtract:

$\sf~m=(1)/(1)$

Divide:

$\sf~m=1$

So the slope is positive.

Write three ways to find 3x2x4

What is a an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A = 3 x 2 x 4

Now , the value of the equation A is A = 24

Now , the number 24 can be written as a product of different numbers

The factors of the number 24 = 1 , 2 , 3 , 4 , 6 , 8 , 12 , 24

So , the three different ways to calculate the equation A = 3 x 2 x 4 is

A = 24

The first equation ,

A = 6 x 4

The second equation ,

A = 3 x 8

The third equation ,

A = 12 x 2

Hence , The three different ways to calculate the equation A = 3 x 2 x 4 is

A = 6 x 4

A = 3 x 8

A = 12 x 2

(3)(2)(4) is how I see it.

•You can do 3*2 = 6 then 6*4 = 24
•You can do 3*4 = 12 then 12*2 = 24
•You can also do 2*4 = 8 then 8*3 = 24

•It equals 24 no matter what way you do it.
