Mathematics

Answer:

m = -3/2

Step-by-step explanation:

Given the following points on the graph, (0, 9) and (2, 6):

Let (x₁, y₁) = (0, 9)

     (x₂, y₂) = (2, 6)

Plug these values into the following slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

m = (6 - 9)/ (2 - 0)

m = -3/2

Therefore, the slope of the graph is -3/2. It has a <em>negative</em> value (hence, a negative slope) because the line is declining from the left side of the graph towards the right.

-16.68 + 1.8s + 2.2 = 3s - 6.4
zlopas [31]

Answer:

s = -6.7

Step-by-step explanation:

- 16.68 + 1.8s + 2.2 = 3s - 6.4

- 16.68 + 2.2 + 1.8s = 3s - 6.4

- 14.48 + 1.8s = 3s - 6.4

Collect like terms

Note: crossing over equals to, the sign will change

Hint: either from

- to +

Or

+ to -

-14.48 + 6.4 = 3s - 1.8s

-8.08 = 3s - 1.8s

-8.08 = 1.2s

Divide both sides by 1.2, to get the value of s

-8.08/1.2 = 1.2s/1.2

-6.7 = s

s = -6.7

What is the solution to the system of equations? "-6x2/5y=8" 1/2x+3y=29
prohojiy [21]

The answer choice which represents a solution to the system of equations is; (–2, 10).

<h3>Which answer choice is a solution to the systems of equations?</h3>

The system of equations as given in the task content is;

-6x - (2/5)y = 8

(1/2)x +3y = 29

Hence, by making x subject in equation 1 and substitution; we have;

x = (-0.4y -8)/6

Hence; (0.4y -8)/12 + 3y = 29.

(0.4y -8) + 36y = 348

35.6y = 356

y = 10

and x = (-0.4(10) -8)/6 = -2.

Find the surface area of the following figure below. Use 3.14 for pi
Studentka2010 [4]
Surface area of cylinder = 2 x pi x r x h + 2 x pi x r*2

So 2 x pi x 4 x 11 + 2 x pi x 4*2 = 376.99

State the domain of the rational function
guajiro [1.7K]

The rational function is defined as a polynomial of two parts. That is numerator and denominator i.e., denominator should not be zero.

Step-by-step explanation:

       The given function is f(x)=13/10-x

Step:1

     apply values to the term x in the given function,

     Take X=1,

      the equation becomes

      f(1)=13/10-1

      f(1)=1.444

      Take X=2,

      the equation becomes,

      f(2)=13/10-8

      f(2)=1.625

similarly,

     f(3)=1.857,

     f(4)=2.167,

     f(5)=2.60,

     f(6)=3.25,

     f(7)=4.33,

     f(8)=6.50,

     f(9)=13,

but for f(10)= 13/10-10

           f(10)=∞

    f(11)=-13,

     f(12)=-6.5,

     f(13)=4.33,.. etc

so, f(x) is positive when the X value is less than 10.

     f(x) is negative when the X value is more than 10.

but f(10)=∞ is never possible

     Therefore, all the numbers are correctly apted expect zero

Find the perimeter of the polygon with the given vertices x(-1,3) y(3,0) z(-1,-2)
Dvinal [7]

x(-1,3) y(3,0) z(-1,-2)

xy

m = (3 + 1)/(0 - 3) = 4/-3 = -4/3

y - 3 = -4/3(x + 1)

y - 3 = -4/3x - 4/3

xy: y = -4/3x + 5/3

yz

m = (0 + 2)/(3 + 1) = 2/4 = 1/2

y = 1/2(x - 3)

yz: y = 1/2x - 3/2

xz

m = (3 + 2)/(-1 + 1) = 5/0 = undefined

y - 3 = undefined(x + 1)

xz: x = -1

xy: y = -4x/3 + 5/3

yz: y = x/2 - 3/2

xz: x = -1
