Step-by-step explanation:

area of an equilateral triangle = [tex]\frac{s^{2} \sqrt{3} }{4}[/tex] (s = length of the side)

area = [tex]\frac{6^{2}\sqrt{3} }{4}[/tex]

c=4a+4b solve for b

Answers

Answer:

[tex]b = -a +\frac{1}{4}c[/tex]

Step-by-step explanation:

Step 1: Flip the equation.

[tex]4a + 4b = c[/tex]

Step 2: Subtract 4a from both sides.

[tex]4a + 4b - 4a = c - 4a[/tex] [tex]4b = c - 4a[/tex] [tex]4b = -4a + c[/tex]

Step 3: Divide both sides by 4.

[tex]\frac{4b}{4}=\frac{-4a}{4} + \frac{c}{4}[/tex] [tex]b = -a + \frac{1}{4}c[/tex]

Therefore, the answer is [tex]b = -a + \frac{1}{4}c[/tex].

Hope you have a lovely rest of your day/night.

Answer:

b = [tex]\frac{c - 4a}{4}[/tex]

Step-by-step explanation:

c = 4a + 4b

Subtract 4a from both sides:

c - 4a = 4a - 4a + 4b

c - 4a = 4b

Divide both sides by 4 to solve for b:

[tex]\frac{c - 4a}{4} = \frac{4b}{4}[/tex]

b = [tex]\frac{c - 4a}{4}[/tex]

Step-by-step explanation:

22. The function C= 75x + 2600 gives the cost, in dollars, for a small company to
manufacture x items. The function R = 225x-X gives the revenue, also in
dollars, for selling x items. How many items should the company produce so
that the cost and revenue are equal?

Answers

Given:

[tex]c=75x+2600\\[/tex]; where c is cost in dollars and x is items sold

[tex]r=225x-x^{2}[/tex]; where r is revenue in dollars and x is items sold

Equations:

[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

Answer:

For cost and revenue to be equal, the company should produce and sell 20 or 130 items.

[tex]x=20\\[/tex] or [tex]x=130[/tex]

Step-by-step explanation:

1. Set the equations equal to each other; [tex]75x+2600=225x-x^2[/tex]

2. Subtract [tex]225x-x^2[/tex] from each side; [tex]x^2-150x+2600=0\\[/tex]

3. Determine quadratic formula variables; [tex]a=1; b=-150; c=2600[/tex]

4. Substitute [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] into quadratic formula; [tex]x=\frac{-(150)\±\sqrt{(-150)^2-4*1*260}}{2*1}[/tex]

5. Solve quadratic formula; [tex]x_{1} = 130[/tex], [tex]x_{2}=20[/tex]

Write the slope-intercept form of the equation to the line parallel to the graph
of y+6=-4(x-1) that passes through the point (2,4).

Answers

Answer:

y = -4x + 12

Step-by-step explanation:

Parallel lines have the same slope. Since the slope of the given equation is -4, then the slope of the other line parallel to it must be the same.

Using the slope, m = -4, and the given point, (2, 4):

Substitute these values into the slope-intercept form:

y = mx + b

4 = -4(2) + b

4 = -8 + b

4 + 8  = -8 + 8 +  b

12 = b

Therefore, the equation of the line parallel to  y + 6 = -4(x - 1) is:

y = -4x + 12

Answer:

4x-2

Step-by-step explanation:

Slope intercept form is y=mx+b, so get y on one side.

do the multiplication first -4(x-1) is -4x+4

Now move the six to the other side; y=-4x+4-6

Simplify, y=-4x-2

Write the equation of the graph in slope-intercept form (y=mx+b).

Write the equation without spaces:

Answers

Answer:

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is. It can have either a positive or a negative value. When a standard form of a linear equation is of the form Ax + By = C, where 'x' and 'y' and 'C' are variables and 'A', 'B' are constants, the slope-intercept form is the most preferred way of expressing a straight line due to its simplicity, as it is very easy to find the slope and the 'y intercept' from the given equation.

Meaning of y = mx + b

y = mx + b is the slope-intercept form of a staight line. In the equation y = mx + b for a straight line, m is called the slope of the line and b is the y-intercept of a line. y = mx+b, where

y ⇒ how far up or down is the line,

x ⇒ how far along is the line,

b ⇒ the value of y when x = 0 and

m ⇒ how steep the line is.

This is determined by m = (difference in y coordinates)/ (difference in x coordinates). Note that difference in y coordinates is indicated as rise or fall and difference in x coordinates is indicated as run.
