If the triangle were reflected across the x-axis, then translated four units to the left,
what would be the value of the x-coordinate of point B?

Answer:

x = -7/2

Step-by-step explanation:

½(4x - 8) = 6x + 10

simplify

2x - 4 = 6x + 10

subtract 6x from both sides

-4x - 4 = 10

add 4 to both sides

-4x = 14

divide both sides with -4

x = -14/4

simplify

x = -7/2

Answer:

½(4x - 8) = 6x + 10

4x-8=12x+20

-20-8=12x-4x

-28=8x

x=-28/8=3.5

Answer:a+b ≥40

5+a≤ b

2.50a+1.50b≤ 105

i believe

Step-by-step explanation:

The equations would be:

a+b ≥40 (cupcakes +cookies must be at least 40 total)

5+a≤ b

(At most 5 more cupcakes then cookies)

2.50a+1.50b≤ 105

(The cost of cookies and cupcakes must be less than $105)

Answer:

Completing the square we get: [tex](x-2)^2-(2)^2[/tex]

and factoring the term we get: [tex]x(x-4)[/tex]

Step-by-step explanation:

We need to complete the square for the expression [tex]x^2-4x[/tex]

For completing the square the expression would be of form [tex]a^2+2ab+b^2=(a+b)^2[/tex]

For given expression we have to add (2)^2 and subtract to make it complete the square.

[tex]x^2-2(x)(2)+(2)^2-(2)^2\\(x-2)^2-(2)^2[/tex]

Now, we have to factor the polynomial using formula [tex](a)^2-(b)^2=(a-b)(a+b)[/tex]

So, [tex](x-2)^2-(2)^2\\=(x-2-2)(x-2+2)\\=(x-4)(x-0)\\=x(x-4)[/tex]

Completing the square we get: [tex](x-2)^2-(2)^2[/tex]

and factoring the term we get: [tex]x(x-4)[/tex]

Given :

Wall measures about 65 feet tall and 80 feet wide.

To Find :

If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion.

Solution :

Let, width of sketch is x.

Since, they are in proportion :

[tex]\dfrac{65}{10}=\dfrac{65+8}{x}\\\\x = \dfrac{10\times 73}{65}\\\\x = 11.23\ feet[/tex]

Therefore, width of sketch should be 11.23 feet.

Hence, this is the required solution.

Answer:

The length of Big Ben shadow is 252.8 feet

Step-by-step explanation:

The given parameters are;

The height of the Big Ben clocktower in London ≈ 316 feet tall

The length of the shadow Shana casts = 4-foot

The height of Shania = 5 feet

Therefore, we have, by similar triangles;

[tex]\dfrac{The \ length \ of \ the \ shadow \ Shana \ casts }{The \ height \ of \ Shania} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{The \ height \ of \ the \ Big \ Ben \ clocktower}[/tex]Substituting the values, gives;

[tex]\dfrac{4 \ feet}{5 \ feet} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{316 \ feet}[/tex]

[tex]The \, length \, of \, the \, shadow \, The \, Big \, Ben \ clocktower \ casts = 316 \ feet \times \dfrac{4 \ feet}{5 \ feet} = 252.8 \ feet[/tex]

The length of the shadow The Big Ben clocktower casts = The length of Big Ben shadow = 252.8 feet

252.8 feet

Answer:

System of Equations

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

We have 28 chickens and 4 rabbits

Step-by-step explanation:

Let the number of chickens be represented by c

The number of rabbits be represented by r

From the question, John counts:a total of 32 heads

32 heads = a total of 32 animals

Hence:

c + r = 32....... Equation 1

c = 32 - r

Also, John counts:

A total of 72 legs in his backyard.

Chickens have: 2 legs

Rabbits have: 4 legs

Hence:

2c + 4r = 72......... Equation 2

System of Equations is:

c + r = 32 ..... Equation 1

2c + 4r = 72......... Equation 2

Lets us substitute 32 - r for c in Equation 2

2(32 - r) + 4r = 72

64 - 2r + 4r = 72

Collect like terms

- 2r + 4r = 72 - 64

2r = 8

r = 8/2

r = 4

This means we have 4 rabbits

Note:

c = 32 - r

r = 4

c = 32 - 4

c = 28

Hence, we have 28 chickens

Given :

A rectangular yard measuring 39 ft by 63 ft is bordered (and surrounded) by a 2 ft fence.

To Find :

The area of this walk.

Solution :

Area of whole park :

[tex]A=39\times 63\ ft^2\\\\A=2457\ ft^2[/tex]

Now, length and breadth after removing the fences is l = 63 - 2( 2) = 59 ft and b = 39 - 2( 2 ) = 35 ft.

Area of inner park :

A' = 35 × 59 ft²

A' = 2065 ft²

Therefore, area of fencing is 2457 - 2065 = 392 ft² .

Hence, this is the required solution.

Step-by-step explanation:

Given

length of rectungular field =50m

its breadth = 40m.

Solution

Area=length×breadth

=50×40

=2000m^2

1)1 square metre =0.000247 acre

2)2000m^2=0.2 hectare

Answer:

3.

Step-by-step explanation:

From the question given above, the following data were obtained:

Logᵦ 8 = 3

Logᵦ 0.5 = – 1

Logᵦ 4B =?

Next, we shall determine the value of B. This can be obtained as follow:

Logᵦ 8 = 3

8 = B³

Take the cube root of both side.

B = 3√8

B = 2

Finally, we shall determine the value of Logᵦ 4B. This can be obtained as follow:

Logᵦ 4B =

B = 2

Logᵦ (4×2) = Logᵦ 8

Recall from the question given:

Logᵦ 8 = 3

Therefore,

Logᵦ 4B = Logᵦ 8 = 3

Thus, the value of Logᵦ 4B is 3.

Answer:

It ends up being 3

210 students brought lunch

Step-by-step explanation:

At school on Friday the ratio of students who purchased a lunch to students who brought lunch was 4:3.

The ratio is

Students who purchased: Students who brought

= 4 : 3

The total proportion

= 4 + 3 = 7

The total number of students from the question is : 490

Hence, The number of students that brought lunch is calculated as:

3/7 × 490

= 210 students

Hence, 210 students brought lunch

Answer:

  Mark the lower tick marks with hour numbers; see what hour corresponds to 2/3 mile

Step-by-step explanation:

The upper number line is marked off in 1/3 mile increments.

The tick marks on the lower line divide the unit distance into 6 parts, instead of 3, so each mark on the lower line corresponds to 1/6 mile.

The problem statement tells you the completion rate is 1/6 mile per hour, so we can number the lower tick marks 0, 1, 2, 3, 4, 5, 6 hours, leaving the marks on the upper number line at 1/3 mile, 2/3 mile, and 1 mile.

Then the lower tick mark we have labeled 4 hours will correspond to the upper tick mark labeled 2/3 mile.

__

To solve the problem using number lines, mark the number lines with values that correspond. Extend the numbering as required to answer the question asked.

Answer:

52.15

Step-by-step explanation:

you need to find how much each pint cost by itself so...

8.94 divided by 6 is 1.49

then 1.49 x 35 = 52.15

and that is your answer

Answer:

$52.15

Step-by-step explanation:

i just dived 8.94 by 6 then multiplyed that answer by 35

Answer:

x=8

Step-by-step explanation:

bc (8-7) =1,  1 time 4 = 4                  (we always do -/+ before multiplication)

 and (10-8)=2, 2 time 2 = 4

since for both you get the same result therefore x=8

(I just get that for my I-ready I was stuck for a period of time than realize it)

Answer: Since FK is half the line, and FH is the whole line 6*2= 12
