========================================================

Explanation:

Let's complete the square

y = x^2 + 8x

y + 16 = x^2 + 8x + 16 .... adding 16 to both sides

y + 16 = (x+4)^2

y = 1(x+4)^2 - 16

We added 16 to both sides to allow the right hand side to factor into a perfect square.

The last line shown above is in the form y = a(x - h)^2 + k where

a = 1

h = -4

k = -16

Note the positive 'a' value indicates we have a minimum.

The vertex is (h,k) = (-4, -16)

The lowest y value possible is at the vertex.

So the smallest y value is y = -16.

This means the smallest possible value of x^2+8x is -16.

Answer:

Step-by-step explanation:

Simplifying

-14 + 1 = rt + -4n

Combine like terms: -14 + 1 = -13

-13 = rt + -4n

Reorder the terms:

-13 = -4n + rt

Solving

-13 = -4n + rt

Solving for variable 'n'.

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

Add '4n' to each side of the equation.

-13 + 4n = -4n + 4n + rt

Combine like terms: -4n + 4n = 0

-13 + 4n = 0 + rt

-13 + 4n = rt

Add '13' to each side of the equation.

-13 + 13 + 4n = 13 + rt

Combine like terms: -13 + 13 = 0

0 + 4n = 13 + rt

4n = 13 + rt

Divide each side by '4'.

n = 3.25 + 0.25rt

Simplifying

n = 3.25 + 0.25rt

Answer:

n = [tex]\frac{rt-q}{-10}[/tex]

Step-by-step explanation:

your equation is -14n+q = rt-4n

subtract q from both sides: -14n = rt - 4n - q

add 4n to both sides: -10n = rt - q

divide both sides by -10: n = [tex]\frac{rt-q}{-10}[/tex]

Answer:

Step-by-step explanation:

"The question is not complete, here is the complete question

A bicycle with 18-in.-diameter wheels has its gears set so that the chain has a 6-in. radius on the front sprocket and 3-in. radius on the rear sprocket. The cyclist pedals at 180 rpm.

Find the linear speed of the bicycle in in/min (correct to at least two decimal places)  

How fast is the bike moving in mph (to two decimal places)?"

Step one:

given data

the diameter of wheels= 18 inches

radius of front sprocket=6 inches

radius of rear sprocket= 3 inches

The cyclist pedals at 180 rpm

The chains move at the same speed, hence

the rear sprocket must make 6/3 revolutions for every one revolution made by the front sprocket

when the rider moves the front sprocket through 180 revs/min

the rear sprocket moves through 180 (6/3)  = 360 revs/min

the linear speed of the bicycle in inches per minute  =

 2π * 9 * 360   = about 20360.16  in/min

The speed in mph

=2π * 9 * 360 * 60 minutes in 1 hr /63360 in/ mile  

=19.28 mph

Answer:

  There are 2 nickels and 6 dimes.

Step-by-step explanation:

Nickels:  x

 Dimes:  y

Constraints:

  0.05x + 0.10y = 0.70

   x + y = 8                   ===>  -0.05 * (x + y = 8)  ===>   -0.05x - 0.05y = -0.4

Add the two equations to eliminate x variable:

  0.05x + 0.10y = 0.70

 -0.05x - 0.05y = -0.4

_________________

                0.05y = 0.3         ===>    y = 6

Substitution to find x:

  x + y = 8

  x + 6 = 8

  x = 2

There are 2 nickels and 6 dimes.

There are 2 nickels and 6 dimes.

Two or more expressions with an Equal sign is called as Equation.

Given,

Aaron has $0.70 worth of nickels and dimes.

total of 8 nickels and dimes altogether

We need to find the number of nickels and number of Dimes

Let Nickels be x and  Dimes be y

By given conditions

0.05x + 0.10y = 0.70

x + y = 8-0.05x - 0.05y = -0.4

Add the two equations to eliminate x variable:

0.05x + 0.10y -0.05x - 0.05y = 0.70 -0.4

0.05y = 0.3

Divide both sides by 0.05

y = 6

Substitution to find x:

x + y = 8

x + 6 = 8

x = 2

Hence, there are 2 nickels and 6 dimes.

The value of 5 is 50, 000.

In mathematics, place value refers to the relative importance of each digit in a number. These locations begin at the unit's location (ones place). The place values of a number's digits are expressed in the following order: ones/units, tens, hundreds, thousands, ten thousands, and so on.

Given:

The population of London is currently estimated at 8.156 million.

Expanding 8.156 million.

The Pythagorean theorem is helpful. For legs a, b, and hypotenuse c, it tells you ...

  c² = a² +b²

  50² = 20² +b²

  b² = 2500 -400 = 2100

Slope of the line = 2

Step-by-step explanation:

Slope of a line through two points lying on the line [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the figure attached,

Given line is passing through two points (0, 1) and (1, 3).

Therefore, slope of the line will be,

Slope = [tex]\frac{3-1}{1-0}[/tex]

          = 2

The slope of the line given in the graph is -0.5.and this can be determined by using the point-slope form and slope-intercept form.

Given :

To determine the slope of the line, the point-slope form can be used. The point-slope form is given by:

[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.

Now, put the values of the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the above equation.

[tex]\dfrac{y-1}{x-0}=\dfrac{0-1}{0.5-0}[/tex]

0.5(y - 1) = -x

[tex]y = -\dfrac{1}{2}x +1[/tex]

Now, compare equation (1) with the slope-intercept form of the line.

m = -0.5

c = 1

So, the slope of the line is -0.5.
