Answer:

L'(-1,1)  M'(1,2)  N(1,-1)

Step-by-step explanation:

Now you just need to plot the 3 points and link them with lines and you will find the new triangle.

Answer:

Step-by-step explanation:

First we need to factorize the given area of the rectangle as shown;

Given

A(x) = x^2-10x+16

Factorize

A(x) = x²-8x-2x+16

A(x) = (x²-8x)-(2x+16)

A(x) = x(x-8)-2(x-8)

A(x) = (x-2)(x-8)

Since area of a rectangle = length ×width

Hence the binomial that represents the width of the pool is w(x) = x-2

b) If the width of the deck is 17feet

Width = x-2

17 = x-2

x = 17+2

x = 19feet

Get the length

Length = x-8

Length = 19-8

Length = 11

Get the perimeter

P = 2(L+W)

P = 2(17+11)

P =2(28)

P = 56feet

Perimeter of the deck is 56feet

Hi there! :)

[tex]\large\boxed{A. \text{ } y = 2x - 12}[/tex]

6x - 3y = 36

Solve for y:

begin isolating by subtracting both sides by 6x:

6x - 6x - 3y = 36 - 6x

-3y = 36 - 6x

Divide both sides by -3 to solve for y:

(-3y) / (-3) = (36 - 6x)/ (-3)

y = -12 + 2x

Rearrange:

y = 2x - 12, or choice A.

Answer:

Value of theta Ф = 1.33 radians

Step-by-step explanation:

We are given :

S= 8

r = 6

We need to find angle Ф

The formula used is: S=rФ

Finding theta Ф by putting values in formula:

[tex]S=r\theta\\\theta=\frac{S}{r}\\ \theta=\frac{8}{6}\\\theta=1.33[/tex]

So, value of theta Ф = 1.33 radians

Answer:

Step-by-step explanation:

Solution :

Given :

Height of the tower , h = 45 m

Weight of the weather vane, mg = 190 N

So the potential energy possessed by the weather vane is given by

E = m x g x h

where, E is potential energy

           m is mass

           g is acceleration due to gravity (taken as 10 m/s2)

           h is height

Therefore,

E = m x g x h

E = (mg) x h

E = 190 x 45

E = 8550 J

Answer:

0

Step-by-step explanation:

To find the number of integer solutions there are to the inequality, we need to  separate [tex]x[/tex] so it is on its own.

[tex]17<5x-8 < 22[/tex] (given inequality)

[tex]25 < 5x < 30[/tex] (add [tex]8[/tex] )

[tex]5 < x < 6[/tex] (divide by [tex]5[/tex] )

Since there are no integers between [tex]5[/tex] and [tex]6[/tex], it means there are 0 integer solutions for the inequality [tex]17 < 5x - 8 < 22[/tex].

Hope this helps :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

a)

the sum of all angles in a quadrilateral must be 360º

y+88+25+35 = 360

y = 360=88-25-35

y = 212º

b)

the sum of all angles in an octagon must be 1080º

45+45+140+140+6y = 1080

6y = 1080-90-280

6y = 710

y = 710/6

y=~ 118,3º

A(X)=(7-2x)(x+5)-(21-6x)(2x-1)

A(X)=(7x+35-2x²-10x)-(42x-21-12x²+6x)

A(X)= -2x²-3x+35+12x²+48x-21

A(X)=10x²+45x+14

Here is your system of equations:

200x + 400y = 3200

y = 2x

Now plug into your calculator to see the graph.

Where the lines cross each other is the point that shows the solution.

Answer:

area of the big triangle is QS*RT, where we know the QS

so we need to derive the area of big triange

the big triange is sum of the larger triangle (QT*RT) + smaller one (TS*RT)

so RT*(5+2.2)=RT(5)+RT(2.2)

the rest is simple to solve

Answer:

She sold 82 brownies

Step-by-step explanation:

164 / 2 = 82

82 x 2 = 164

The number of brownies veronica sale is 82 brownies.

We are given that;

Number of brownies made= 164

Now,

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

To find out how many brownies Veronica sold, we need to divide the total number of brownies she made by 2.

This is because half of something means one part out of two equal parts. Using this method, we get:

[tex]$\frac{164}{2} = 82$[/tex]

Therefore, by unitary method the answer will be 82 brownies.

Answer:

The slope of 8 is 0 and the slope of 9 is undefined

Answer:

60 CDs

Step-by-step explanation:

Given that :

Price of program = $0.5

Price of music = $5

Cost of production :

Program = $0.15 per program

CD = $1.75 per CD

Revenue made= $400

Profit made = $265

Number of CD produced =?

Let Number of CD's = x and program = y

$(0.5y + 5x) = 400

Y = (400 - 5x) / 0.5

y = 800 - 10x

Production :

$(1.75x + 0.15y)

Total cost of production - Revenue made = profit

(1.75x + 0.15y) - (5x + 0.5y) = 265

1.75x + 0.15y - 5x - 0.5y = 265

1.75x - 5x 0.15y - 0.15y = 265

3.25x + 0.35y = 265 - - - (2)

Put y = 800 - 10x in (2)

3.25x + 0.35y = 265

3.25x + 0.35(800 - 10x) = 265

3.25x + 280 - 3.5x = 265

-0.25x = - 15

x = 15/ 0.25

x = 60

Answer:

option (4)

Step-by-step explanation:

The general form of a quadratic function is given by :

[tex]f (x) = ax^ 2 + bx + c[/tex]

Where a,b and c are real numbers and a is nonzero.

Option (1)

[tex]f (x) = 3x^ 2 + 12x + 5[/tex]

It is a quadratic function. Here, a = 3, b = 12 and c = 5

Option (2),

[tex]f (x) = x^ 2 + x + 1[/tex]

It is a quadratic function where a = 1, b = 1 and c =1

Option (3),

[tex]f(x)=5x^ 2 + 8x[/tex]

It can also be written as :

[tex]f(x)=5x^ 2 + 8x+0[/tex]

It is a quadratic function where a = 5, b = 8 and c = 0

Option (4),

It can also be written as :

f(x) = 5x + 3

It is a linear function. It is not a quadratic function.

Hence, option (4) is the correct option. It is not a quadratic function.
