Answer:

a=b+cd

c=b/c/a or c^2=b/a

Btw ^2 means squared or to the second power.

this might no be the answer you are looking for though

Help find y .. slope is m=-5/8
goblinko [34]

y = 8

using the ' gradient formula' m = (y₂ - y₁)/(x₂ - x₁)

with (x₁, y₁) = (3, 3), (x₂, y₂) = (- 5, y) and m = - \frac{5}{8}

(y - 3)/( - 5 - 3) = - \frac{5}{8}

(y - 3)/(-8) = - \frac{5}{8}

multiply both sides by - 8 to eliminate fractions

y - 3 = 5

add 3 to both sides

y = 5 + 3 =8

PLZ HELP MEEEEE!!! i suck at fractions umu
Reil [10]

Answer:

The area of the baseboard is 135\ m^2

Step-by-step explanation:

We have,

Length of the bed, l = 15 m

Width of the bed, b = 9/10 m

It is required to find the area of the baseboard. It is a shape of rectangle. The area of a rectangular shape is given by :

A=l\times b\\\\A=15\ m\times \dfrac{9}{10}\ m\\\\A=\dfrac{135}{10}\ m^2\\\\A=135\ m^2

So, the area of the baseboard is 135\ m^2

71 and 72 please help.
Hitman42 [59]
71) The triangle is isos. so the base angles are congruent

2a+b=5b-3a
5a=4b

The angles of a triangle all add up to 180

180=5a -2b + 2a +b + 5b -3a
180=4a+4b

Substitute 4b with 5a

180=4a+5a
180=9a
a=20

And substitute a into the equation: 5a=4b to solve for b and solve for the measurements of the angles


72) Angles that are supplementary add up to 180

8(y-x)+124=180
9x-2y+124=180

8x-8y=56
(9x-2y=56)4

Use elimination to solve for the variables

8x-8y=56
-(36x-8y=224)
-28x=-168
x=48

Substitute x into the other equation to solve for y and find the measurements of the angles

Which property justifies the fact that 5(x-2) is equivalent to 5x-10
Mazyrski [523]
Hey there! :D

The distributive property is what makes 5(x-2) to 5x-10

The distributive property states that a(b+c)= ab+ac

So, 5(x-2)= 5x-10

I hope this helps!

You are constructing a cardboard box with the dimensions 2 m by 4 m. You then cut equal-size squares ( x by x squares) from each
romanna [79]

Answer:

<em>x</em> = 0.423 m

Step-by-step explanation:

Volume of the box = length × width × height

The height is given by the length of a side of the square.

height = <em>x</em>

The width and height are gotten by subtracting twice the side of the square form each dimension of the cardboard (since two squares are cut along each dimension).

length = 4 - 2<em>x</em>

width = 2 - 2<em>x</em>

<em />

Volume, V = x(4-2x)(2-2x) = 8x - 12x^2 + 4x^3

To find the maximum, we differentiate <em>V</em> with respect to <em>x</em> and equate the derivative to 0.

\dfrac{dV}{dx} = 8-24x+12x^2 = 0

Simplify by dividing by 4.

2-6x+3x^2 = 0

Using the quadratic formula,

<em>x</em> = 0.423 m or <em>x</em> = 1.577 m

To determine which values gives maximum, we differentiate the first derivative which gives

\dfrac{d^2V}{dx^2} = -6+6x

The maximum value occurs when \dfrac{d^2V}{dx^2} is negative.

At <em>x</em> = 1.577,

\dfrac{d^2V}{dx^2} = -6+6(1.577) = 3.462

This is positive, so it is minimum.

At <em>x</em> = 0.423,

\dfrac{d^2V}{dx^2} = -6+6(0.423) = -3.462

This gives a negative value. Therefore, it is a maximum.

Hence, the maximum volume is obtained when <em>x</em> = 0.423 m.
