Can someone simplify this for me and the answer I don’t know help quickly!!!

The equation of the parallel lines will be y = 0.8x and y = 0.8x - 3.2.

Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.

The intercepts of the line are (0, -3.2) and (4, 0). Then the equation of the line is given as,

y + 3.2 = [(0 + 3.2) / (4 - 0)](x - 0)

y = 0.8x - 3.2

The equation of the other parallel line that passes through the origin will be given as,

y = 0.8x

The equation of the parallel lines will be y = 0.8x and y = 0.8x - 3.2.

THE SMALLEST FORMS:

- smallest prism ---> the cube with all sides 2 ==> the volume is 2*2*2 = 8 cm^3

- smallest pyramid number one ---> the pyramid with base sides 2 and the height also 2 ==> the volume is (1/3)*2*2*2 = 8/3 cm^3

- smallest pyramid number two ---> the pyramid with base sides 2 and the lateral sides also 2 ==> the radius of the base is sqrt(2) ==> [pyramid_height]^2 = [lateral_side]^2 - [base_radius]^2 = 2^2 - sqrt(2)^2 = 4 - 2 = 2 ==> pyramid_height = sqrt(2) ==> the volume is (1/3)*2*2*sqrt(2) = 4*sqrt(2)/3 cm^3

- smallest cylinder --> the cylinder of diameter 2 and height also 2 ==> the radius is diameter/2 = 2/2 = 1 ==> the volume is pi*(radius^2)*height = pi*(1^2)*2 = pi*1*2 = 2*pi cm^3

The lesser volume is the volume of the smallest pyramid number two. ==> it's wax cost is approximately 0.0075 * 4 * 1.42 / 3 $ per candle = 0.014 $ per candle ==> the total cost  per candle is approximately 0.014 + 1.6 = 1.614 $ per candle.

THE BIGGEST FORMS:

- biggest prism ---> the cube with all sides 10 ==> the volume is 10*10*10 = 1000 cm^3

- biggest pyramid number one ---> the pyramid with base sides 10 and the height also 10 ==> the volume is (1/3)*10*10*10 = 1000/3 cm^3

- biggest pyramid number two ---> the pyramid with base sides 10 and the lateral sides also 10 ==> the radius of the base is 5*sqrt(2) ==> [pyramid_height]^2 = [lateral_side]^2 - [base_radius]^2 = 10^2 - [5*sqrt(2)]^2 = 100 - 50 = 50 ==> pyramid_height = 5*sqrt(2) ==> the volume is (1/3)*10*10*5*sqrt(2) = 500*sqrt(2)/3 cm^3

- biggest cylinder --> the cylinder of diameter 10 and height also 10 ==> the radius is diameter/2 = 10/2 = 5 ==> the volume is pi*(radius^2)*height = pi*(5^2)*10 = pi*25*10 = 250*pi cm^3

The bigger volume is the volume of the biggest prism (the side-10 cube). ==> it's wax cost is  0.0075 * 1000 $ per candle = 7.5 $ per candle ==> the total cost per candle is 7.5 + 1.6 = 9.1 $ per candle

The range of the cost is the interval [1.614 ; 9.1]. Depending on other prices on the market,  you greed, and other factors you will put a profit margin: maybe 20% of the cost ; maybe a fixed margin like 5$. So the price per candle will be the cost per candle plus the profit margin per candle.

If I were to choose the base length I would have to say 6 because it is the arithmetic mean between 2 and 10: (2+10)/2 = 12/2 = 6. 2cm is too small, and 10cm is too big.

Also if you start with a rectangle of length 10 and width 2 and you have to find the rectangle with the largest area by being allowed to increase the width and decrease the width with the same quantity you get this:

Area of the new rectangle is (10-x)(2+x) = -x^2 + 8x + 20 = -x^2 + 8x -16 + 36 = -(x^2 - 2*x*4 + 4^2) + 36 = -(x-4)^2 + 36 = 36 - (x-4)^2 which has the maximum value of 36 because out of 36 you subtract a positive value. You get the maximum when (x-4)^2 = 0 ==> x-4=0 ==> x=4

The new length is 10-4=6 and the new width is 2+4=6.

Next I would choose the height of the prism (I like prisms :P) to be [the_golden_ratio]*[base_side] which is approximately 1.618 * 6 = 9.708 which I would round up to 10. ==> The volume would be 6*6*10 = 360 cm^3. ==> the cost would be 0.0075*360 + 1.6 = 2.7 + 1.6 = 4.3 $ per candle. And because my candle is so perfect I'd put the profit margin to be 5.69 $ per candle so I can proudly show it in the store with the price of 4.3 + 5.69 = 9.99 $ :)

Answer:

(5, -4)

Step-by-step explanation:

Substitute y from the first equation into the second equation:

-4x - 6(-2x + 6) = 4

Simplify:

-4x + 12x - 36 = 4

8x = 40

x = 5

The only answer choice where x = 5 is (5, -4).

Answer:

[tex]\boxed {\boxed {\sf (5, -4)}}[/tex]

Step-by-step explanation:

We are given the two equations:

[tex]y= -2x+6 \\-4x-6y=4[/tex]

We are asked to solve by substitution. Since we know that y is equal to -2x+6, so we can substitute the expression in for y in the second equation.

[tex]-4x-6y=4[/tex]

[tex]-4x-6(-2x+6)=4[/tex]

Now, solve for x by isolating the variable on one side of the equation.

First, distribute the -6 into the expression. Multiply each term in the parentheses by -6.

[tex]-4x+ (-6*-2x)+(-6*6)=4[/tex]

[tex]-4x+12x+(-6*6)=4[/tex]

[tex]-4x+12x-36=4[/tex]

Combine like terms. There are 2 x terms that can be added.

[tex](-4x+12x)-36=4[/tex]

[tex]8x-36=4[/tex]

36 is being subtracted from 8x. The inverse of subtraction is addition, so add 36 to both sides of the equation.

[tex]8x-36+36=4+36[/tex]

[tex]8x=40[/tex]

x is being multiplied by 8. The inverse of multiplication is division, so divide both sides by 8.

[tex]\frac{8x}{8} =\frac{40}{8}[/tex]

[tex]x=5[/tex]

x is known, so we can find y using the first equation.

[tex]y=-2x+6[/tex]

x is equal to 5, so substitute the value in.

[tex]y=-2(5)+6[/tex]

Multiply first.

[tex]y=-10+6[/tex]

Add.

[tex]y=-4[/tex]

A solution is written as (x,y). So, the solution to this equation is (5, -4).

Step-by-step explanation:

The commission of the salesmen with the given ratio will be $175.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

The commission is $100 for $1000 in sales.

Ratio of commission to sales = 100/1000 = 0.1

With the same ratio,

Commission/1750 = 0.1

Commission = 1750 x 0.1 = $175

Hence "The commission of the salesmen with the given ratio will be $175".
