-14n⁴ + 7n² + 8n + 7

Step-by-step explanation:

(8n - 3n⁴ + 10n²) - (3n² + 11n⁴ - 7)

= 8n - 3n⁴ + 10n² - 3n² - 11n⁴ + 7

= -3n⁴ - 11n⁴ + 10n² - 3n² + 8n + 7

= -14n⁴ + 7n² + 8n + 7

remember x is bigger than y

Answer: x = 3.2 + 0.6y

Step-by-step explanation: Simplifying

5x + -3y = 16

Solving

5x + -3y = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

5x + -3y + 3y = 16 + 3y

Combine like terms: -3y + 3y = 0

5x + 0 = 16 + 3y

5x = 16 + 3y

Divide each side by '5'.

x = 3.2 + 0.6y

Simplifying

x = 3.2 + 0.6y

x = -5 + 5√3

Step-by-step explanation:

A = ℓ × w

50 = (x + 10) × x

50 = x² + 10x

x² + 10x - 50 = 0

x = [-b ± √(b² - 4ac)] / 2a

x = [-10 ± √(10² - 4(1)(-50))] / 2(1)

x = [-10 ± √(100 - (-200))]/2

x = [-10 ± √300]/2

x = [-10 ± 10√3]/2

x = [-5 ± 5√3]

because x is a unit of length, it is positive

x = -5 + 5√3

Answer:

0.5

Step-by-step explanation:

convert 2.4% to .024 just by moving it two spaces to the left!

(.024)(20) = .48

Answer:

The second choice.

Step-by-step explanation:

A linear functions graph is a straight line.

Answer:

See below

Step-by-step explanation:

I hope you wrote down the right equation using a minus sign instead of a plus.

Rounding 96.26 off to just 96  and then rounding 62.74 off to 62, you can subtract the two in your head real quick.

96 - 62 = 34

So using this estimation you can see that the answer of 159 is no where near correct.

Answer:

250 Hamburgers

Step-by-step explanation:

575 is total

Hamburger is x

Cheesburgers is (x-75) as it is 75 less than the number of hamburgers

x + (x-75) = 575

2x -75 = 575

2x = 500

x = 250

Answer:  The correct answer is:  " x = 0 " .

________

Step-by-step explanation:

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Method 1)

________

Subtract "8" from each side of the equation:

________

  → " 8 + 8x − 8 = 8 − 8 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            " +8 − 8 = 0 " ;

  →  and we are left with "8x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(8 − 8)" = 0 ;

________

And we are left with:

  →  " 8x = 0 " ;

________

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 2)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Subtract "8" from each side of the equation; in the following manner:

________

   8  +  8x    =    8 ;

 - 8             =   - 8 ;

_____________

   0  +  8x    =    0 ;

→ We have:  " 0 + 8x = 0 " ;

→ Note: On the "left-hand side" ; we have:

                 " 0 + 8x " ;

  We can simplify this to "8x" ; since the "addition property of zero" states that when "0" is added to any value; the resulting value does not change.

Now, we can bring down the "0" from the "right-hand side" of the equation;

And we can rewrite our equation as:

________

   → " 8x = 0 " ;

Now, divide each side of the equation by "8" ;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

  →  8x / 8 =  0/8 ;

to get:

  →  " x = 0 " ;

  →  which is the correct answer.

________

Method 3)

________

Given:  " 8 + 8x = 8 " ;  Solve for "x" ;

________

Divide each side of the equation by "8" ;

________

  → " [tex]\frac{(8 + 8x)}{8} =\frac{8}{8}[/tex] " ;

________

To solve:

________

Note: On the "right-hand side" of the equation:

________

Take note that: " [tex]\frac{8}{8} =[/tex] (8 ÷ 8) = 1 " ;

________

Rewrite the equation as:

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;

________

To solve:

________

Note:  " [tex]\frac{x}{y} = z[/tex] " ;  ↔ [tex]x = z*y[/tex] ; [tex](y\neq 0)[/tex] ;

________

 →  " [tex]\frac{(8 + 8x)}{8} =1[/tex]  "  ;  

 →  From the "left-hand side" of the equation;

      Let us simplify:

________

 →  " [tex]\frac{(8 + 8x)}{8} = \frac{8}{8} + \frac{8x}{8} = 1 + x[/tex] " ;  

Now, bring down the "1" from the "right-hand side" of the equation;

and rewrite the equation:

________

 →  " 1 + x = 1 " ;

Now, subtract "1" from each side of the equation;

   to isolate "x" on one side of the equation;

   & to solve for "x" :

________

     " 1 + x − 1 = 1 − 1 " ;

  → On the "left-hand side" of the equation:

          Note the following "like terms" :

            +1 − 1 = 0 " ;

  →  and we are left with "x" on the "left-hand side" of the equation.

  → On the "right hand side" of the equation:

         The "(1 − 1)" = 0 ;

  → And we are left with:

      →  " x = 0 " ;

      → which is the correct answer!

________

The correct answer is:  " x = 0 " .

Answer:

The missing side would be 6.

And the area would be 54.

Step-by-step explanation:

The perimeter equals 30, that's the outside of the rectangle. They give you a part of the perimeter, 9ft. So 9ft and there's another 9ft on the bottom line, (because it is equal to the top width) Which equals 18. To get the other sides you need to subtract 18 from the whole perimeter, 30. Which gives you 12. And there's two sides left, so divide by 2, and you have 6 on each side(left and right sides) Perimeter is adding all the sides up.

And the Area formula is Area=Length times Width. Area=9ft×6ft Which equals 54.

Answer:

But what do we have to do ? like add subtract or multiply?  i dont know

Step-by-step explanation:

Answer:

The value of the algebraic expression when n is given as 6 will be 38.

An algebraic expression is when we use numbers and words in solving a particular mathematical question.

Based on the information given in the question, the expression will be:

= 1 + 7n - 5

Note that the value of n = 6

Therefore, 1 + 7n - 5 will be:

= 1 + 7n - 5

= 1 + 7(6) - 5

= 1 + 42 - 5

= 38

Step-by-step explanation:Therefore, the value of the algebraic expression when n is given as 6 is 38.

y= - 3/2x+4 or y= - 1.5x+4

Step-by-step explanation:

Slope Intercept Form: y=mx+b

3x+2y=8

2y= - 3x+8

y= - 3/2x+4 or y= - 1.5x+4

Convert to Slope-Intercept Form to graph 3x + 2y = 8.The Slope : -3/2The y-intercept: y = -3x/2 + 4

What is Slope?
The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

Solve the equation for y resulting in the y = mx + b
Where,
m = slope
b = the y intercept think b beginning.
3x + 2y = 8
Subtracting 3x both side
3x + 2y - 3x = 8 - 3x2y = 8 - 3x
Dividing both side by 22y/2 = 8/2 - 3x/2y = 4 - 3x/2y = -3x/2 + 4
So, m = -3/2and b = 4

Hence, Slope-intercept is y = -3x/2 + 4
