Step-by-step explanation:

[tex]Domain:\\c-4\neq0\ \wedge\ c-5\neq0\Rightarrow c\neq4\ \wedge\ c\neq5\\\\\dfrac{c}{c-5}=\dfrac{4}{c-4}\qquad\text{cross multiply}\\\\c(c-4)=4(c-5)\qquad\text{use the distributive property}\\\\c^2-4c=4c-20\qquad\text{subtract}\ 4c\ \text{from both sides}\\\\c^2-8c=-20\qquad\text{add 20 to both sides}\\\\c^2-8c+20=0\qquad\text{use the quadratic formula}[/tex]

[tex]\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac<0,\ \text{then the equation has no solution}\\\\\text{if}\ b^2-4ac=0,\ \text{then the equation has one solution}\ x=\dfrac{-b}{2a}\\\\\text{if}\ b^2-4ac>0,\ \text{then the equation has two solutions}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]x^2-8x+20=0\\\\a=1,\ b=-8,\ c=20\\\\b^2-4ac=(-8)^2-4(1)(20)=64-80=-16<0\\\\\bold{NO\ REAL\ SOLUTIONS}[/tex]

[tex]\text{In the set of complex numbers:}\\\\i=\sqrt{-1}\\\\\text{therefore}\ \sqrt{b^2-4ac}=\sqrt{-16}=\sqrt{(16)(-1)}=\sqrt{16}\cdot\sqrt{-1}=4i\\\\x=\dfrac{-(-8)\pm4i}{2(1)}=\dfrac{8\pm4i}{2}=\dfrac{8}{2}\pm\dfrac{4i}{2}=4\pm2i[/tex]

[tex] \frac{c}{c - 5} = \frac{4}{c - 4} [/tex]

[tex](c - 5)(c - 4) \times \frac{c}{c - 5} = \frac{4}{c - 4} \times (c - 5)(c - 4)[/tex]

[tex](c - 4) \times c = 4(c - 5)[/tex]

With c≠4, 5

[tex] {c}^{2} - 4c = 4c - 20[/tex]

[tex] {c}^{2} - 8c + 20 = 0[/tex]

[tex]c = \frac{2 - + \sqrt{2 - 20} }{2} [/tex]

But 2-20 is negative, therefore there isn't any real solution to this equation.

Answer:

15200cm^2

Step-by-step explanation:

we can separate this into 2 equivalent triangles , 2 equivalent rectangles, and 1 extra rectangle.

the area of a triangle is 1/2b*h so 40*60*1/2=1200

we have 2 of these triangles so the area of the triangles in total is 2400.

next, the 2 equivalent rectangles. the area of a rectangle is b*h is 80*50= 4000

we have 2 so the area of these rectangles in total is 8000.

lastly we have one more rectangle 60*80=4800.

then we add all these up 2400+8000+4800= 15200

add unit

15200cm^2

and we're done

Answer:

Step-by-step explanation:

I wonder if it wants 3.80 per gallon?

Perhaps the imperial value which would have been 4.50 per gallon which is an imperial gallon (used in Canada). It's hard to tell. I would have thought 3.78 should be more than close enough.

Answer:

$3.79/$4.55

Step-by-step explanation:

1. How many liters in a gallon: 3.79 l (US), 4.55 l (Imp)

2. Cost of gas/gallon: 3.79 liter * $1/liter = $3.79 (US), $4.55 (Imp)

From what you say, using the US gallon, since both answers round to the same number (since there is no currency below the cent), it wouldn't matter too much. Also, unit conversions should not lead to different answers.

Answer:

Step-by-step explanation:

Use FOIL:  (a + b)(c + d) = ac + ad + bc + bd

(2x - 3y)(4x - y) = (2x)(4x) + (2x)(-y) + (-3y)(4x) + (-3y)(-y)

= 8x² - 2xy - 12xy + 3y²

combine like terms

= 8x² + (-2xy - 12xy) + 3y² = 8x² - 14xy + 3y²

You must FOIL (first, outside, inside, last)

First (The first number/variable of each parentheses must be multiplied together)

(2x - 3y)(4x - y)

[tex]8x^{2}[/tex]

Outside (The outside number/variable of each parentheses must be multiplied together)

(2x - 3y)(4x - y)

-2xy

Inside (The inside number/variable of each parentheses must be multiplied together)

(2x - 3y)(4x - y)

-12xy

Last (The last number/variable of each parentheses must be multiplied together)

(2x - 3y)(4x - y)

[tex]3y^{2}[/tex]

Now add/subtract each FOIL answer according to its sign

[tex]8x^{2}[/tex] - 2xy - 12xy + [tex]3y^{2}[/tex]

Combine like terms

[tex]8x^{2}[/tex] + [tex]3y^{2}[/tex] - 14xy

Answer:

The desired equation is y = x + 8.

Step-by-step explanation:

As we move right from (-2,6) to (4,12), x increases by 6 and y also increases by 6.  Thus, the slope, m, m = rise / run, is m = 6/6, or just m = 1.

Start with the slope intercept form y = mx + b.  Since m = 1, we now have y = x + b.  Subbing 4 for x, 12 for y, we can find b:  12 = 4 + b.  Thus, b = 8.

The desired equation is y = x + 8.

Answer:

The answer to your question is y=1x+8

Step-by-step explanation: We already know that the slope formula is:

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

Substitute the values to find the slope

m= 12-6/4-(-2)

m= 6/4+2

m= 6/6

m=1, so, therefore, the slope is 1

And the y-intercept would be 8

Answer:

-0.8 and 0.75.

Step-by-step explanation:

20x^4 + x^3 + 8x^2 + x – 12 = 0

by the rational roots theorem:-

The leading coefficient is 20 with factors +/-  1,2,4,5,10,20

and the constant is -12 with factors  +/- 1,2,3,4,6,12

so there are many possible roots like -1, 2, 3/4 3/5 , -4/5 .....

Drawing a graph would be the quickest way to do this,  either manually, using graphical software or a graphical calculator.

I used the latter and got 2 rational roots -0.8 and 0.75.

The rational roots of the polynomial f(x) = 20[tex]x^4[/tex] + [tex]x^3[/tex] + 8[tex]x^2[/tex] + x – 12 is -0.8 and 0.75 and this can be determined by sketching the graph of the given polynomial.

Given :

f(x) = 20[tex]x^4[/tex] + [tex]x^3[/tex] + 8[tex]x^2[/tex] + x – 12

The following steps can be used in order to determine the rational roots of the given polynomial:

Step 1 - Write the polynomial equation.

f(x) = 20[tex]x^4[/tex] + [tex]x^3[/tex] + 8[tex]x^2[/tex] + x – 12

Step 2 - Draw the graph of the above polynomial equation.

Step 3 - The coefficient of [tex]x^4[/tex] is 20 with factors +/-  1,2,4,5,10,20

Step 4 - The constant term of the given polynomial is -12 with factors  +/- 1,2,3,4,6,12.

Step 5 - So, from the polynomial equation, the two rational roots are -0.8 and 0.75.

x=26 2/3

80-26 2/3= 53 1.3

Answer:

53 1/3 for $7.80, and 26 2/3 for $11.40

Step-by-step explanation:

x*11.4=11.4x

(80-x)*7.8=624-7.8

9*80=720

Those three steps are because he wants to make 80 pounds out of $9, $11.40 for a pound, and then a pound for $7.80. Since the total is 80 pounds, it could be 11.4 for x pounds and 7.8 for 80-x pounds. Then the equation is:

11.4x+624-7.8x=720

The sample space when the spinner that's divided into two sections is spun twice is; {SG, GG, SS, GS}

We are given that the sections are labeled STOP and GO.

Now the spinner is divided into two equally sized sections as S and G.

Step-by-step explanation:

The average profit from the sale of 1 piece of furniture = x+4

The average number of pieces of furniture that can be made using the current supply of raw materials = x - 4

The average profit = The average profit from the sale of 1 piece × The average number of pices that can be made

Hence,

[tex]F(x)=x^2-4^2\\ \\F(x)=x^2-16[/tex]

Answer:

y = 2x - 5

Step-by-step explanation:

The equation has to have the same slope -- in this case, it is 2 -- to be parallel to 2x - y = 4.

Now we have y = 2x - k.

Then, we plug in the coordinates to our new equation to solve for k.

-1 = 2(2)-k

-1 = 4-k

k = 5

So the final equation would be y = 2x - 5

Answer: x= -7/11

Step-by-step explanation:

13x+17+5x=7x+10

collect the like terms by adding their coefficients

18x+17=7x+10

move variable to the left side and change its sign

18x-7x+17=10

move constant to the right side and change its sign

18x-7x=10-17

collect the like terms

11x=10-17

calculate the difference

11x= -7

divide both sides by 11

x= -7/11

The solution to this equation 3x +17 + 5x = 7x + 10 is x = -7

The solution to this equation 3x +17 + 5x = 7x + 10

Given equation is:

3x +17 + 5x = 7x + 10

To find the value of x, combine the like terms by adding or subtraction.

3x + 5x - 7x = 10 - 17

x = - 7

Therefore, x = -7 is the solution to this equation 3x +17 + 5x = 7x + 10

The range is all the possible values of g(x).  Since we can't take the square root of a negative number, the lowest that g(x) can be is:

g(x) = √0 - 3

g(x) = -3

The highest that g(x) can be is:

g(x) = √∞ - 3

g(x) = ∞
