A dilation with a scale factor of 1/2 is applied to the three sides of Triangle ABC to
create Triangle A'B'C'.
The side lengths of Triangle ABC are: A = 4ft, B = 3ft, C = 5ft.
What are the lengths of the sides on the new Triangle A'B'C'?

A. A' = 8ft, B' = 6ft, C' = 10ft

B. A' = 2ft, B' = 1.5ft, C' = 2.5ft

C. A' = 3.5ft, B' = 2.5ft, C' = 4.5ft

D. A' = 4.5ft, B' = 3.5ft, C' = 5.5ft

Answer:

2m + 3

Step-by-step explanation:

Jake has 3 more than twice the number of marbles that Kylie has. Let m represent the number of marbles Kylie has.

3 + twice of Kylie's marbles = twice of Kylie's marbles + 3

The amount of marbles kylie has is represented with m, making it (2 x m) + 3 = 2m + 3.

Answer:

LV = OE =34

Step-by-step explanation:

Due to the rectangle theory,

LV = OE

3x + 10 = 5x-6

-2x = - 16

x = 8

LV = 3(8) +10 = 34

OE= 5(8)-6 = 34

Answer:

268 adult and 292 student tickets sold

Step-by-step explanation:

a = number  adult tickets sold

s =  number student tickets sold

a + s = 560

8a + 3.50s = 3166

a = 268 adult tickets

s = 292 student tickets

The statement that is true about the given sample is that;

B. The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,

We are given;

Sample size; n = 420

Sample proportion; p^ = 65%

Now, from the sample size and proportion, we can say that;

Exactly 65% of the surveyed customers were not satisfied with the cell phone service. Now, this only represents those surveyed and not the entire population. Thus it is not exactly 65% of all customers that are not satisfied with the cell phone service.

Option B is correct because the 420 customers surveyed is a sample from the population of all their customers within the last year.

Answer:

y = 140

Step-by-step explanation:

All angles inside the triangle will equal 180

Set your formula up as

180 = x + 120 + 20

180 - 120 - 20 = x

40 = x

y+x will also equal 180, therefore

180 = y + x

180 = y + 40

180 - 40 = y

140 = y

If g is a vertical translation of f, the number of  units and in the direction f translated to form g is,  7 units and downward  direction

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

Two functions,

f(x) = x + 4

g(x) = x – 3

the difference in values of function f(x) & g(x)

f(x) -  g(x) =  x + 4 - ( x – 3 )

                =  x + 4 - x +3

                =    7

So, if we subtract 7 from the function f(x)

⇒    f(x) - 7

⇒    x + 4 - 7

⇒    x  - 3

So, vertical translation required is  value 7 and in downward direction

Answer:

143cm

Step-by-step explanation:

Area=2(l+b)

Substitute the values for the variables.

66=2(l+22/5)

66=2xl+2x22

5

66=2l+44

5

Cross multiply

66x5=2l+44

330=2l+44

Collect like terms

-2l = 44-330

-2l = -286

-2l = -286

-2 -2

l=143

The missing length is 143m.

Answer:

The zeros are -2, 1, and 2

Step-by-step explanation:

You have to set each individual equation equal to zero.

ex: (x+2) x+2=0 move the number to the right hand side to get x alone x=-2

as for the y intercept I don't know

Answer:

see explanation

Step-by-step explanation:

g(x) = (x + 2)(x - 1)(x - 2)

To find the zeros let g(x) = 0 , then

(x + 2)(x - 1)(x - 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

The zeros are x = - 2, x = 1, x = 2

To find the y- intercept substitute x = 0 into g(x)

g(0) = (0 + 2)(0 - 1)(0 - 2) = 2(- 1)(- 2) = 2 × 2 = 4

The y- intercept is 4 or (0, 4 )

Answer:

Always try to isolate the variable by doing the INVERSE operation of the given.
so x-5=6
So its -5
You add 5 since its the inverse of it.
So add 5 to both sides or (c)

Answer:

C.) Add 5 to both sides.

Step-by-step explanation:

x - 5 = 6

Add five to both sides.

x - 5 = 6

 + 5  + 5

-5 and +5 cancel out. 6 + 5 is 11.

x = 11

Answer:

The length of the missing leg is six

Step-by-step explanation:

Assuming that this is a right triangle, you can use the Pythagoras theorem

12^2+x^2=sqrt180^2

144+x^2=180

x^2=36

x=6

Therefore, the length of the missing leg is six.

Answer:

Taking the above as a right angled triangle...

Pythagoras' rule can be applied to get the Missing side.

It goes...

Hyp² = Opp² + Adj²

Which translates to Hypotenuse, Opposite and Adjacent respectively.

Hyp = √180

Opp= 12

So we're missing Adj

Making adj the subject.

Adj = √ Hyp² – Opp²

= √[(√180)² – (12)²

= √ [ 180 – 144]

= √36

Adj = 6ft.

The width of the rectangle, for which area and length provided in polynomial equation form is,

[tex](x^43x^3+8x^2+4x)[/tex]

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of rectangle and (b) is the width of the rectangle

The area of the given rectangle is,

[tex]A=(x^4 +4x^3 +3x^2 - 4x - 4),[/tex]

The length of the given rectangle is,

[tex]L=x^3+ 5x^2 +8x+ 4).[/tex]

As, the area of a rectangle is the product of the length and the width of the rectangle. Let suppose the width of the rectangle is f(x). Therefore,

[tex](x^4 +4x^3 +3x^2 - 4x - 4)=(x^3+ 5x^2 +8x+ 4)\times f(x)[/tex]

Solve it further as,

[tex]f(x)=(x^4 +4x^3 +3x^2 - 4x - 4)-(x^3+ 5x^2 +8x+ 4) \\f(x)=(x^4 +4x^3 +3x^2 - 4x - 4-x^3+ 5x^2 +8x+ 4[/tex]

Separate the like terms with same power of variable as,

[tex]f(x)=x^4 +4x^3-x^3 +3x^2 + 5x^2- 4x +8x- 4 + 4\\f(x)=x^43x^3+8x^2+4x[/tex]

Hence, the width of the rectangle, for which area and length provided in polynomial equation form is,
