Answer:

[tex]perimeter= 14\,x\,+ \,4[/tex]

Step-by-step explanation:

Recall the formula for the perimeter rectangle (the addition of all rectangle\s sides): That is: twice the width ( 4x)  plus twice the length (3x+2);

[tex]perimeter=2\,*\,width \,+\,2\,*\,length\\perimeter = 2\,(4\,x)+2\,(3\,x+2)\\perimeter= 8\,x+6\,x+4\\perimeter= 14\,x\,+ \,4[/tex]

Answer:

20

Step-by-step explanation:

To make these parallel, 2 and 5 would have to be corresponding angles, meaning that they have equal angle measure:

3x-20=x+20

3x=x+40

2x=40

x=20

Hope this helps!

Answer:

x= 20

Step-by-step explanation:

To make the lines parallel, angle 2  would equal angle 5

3x-20 = x+20

Subtract x from each side

2x -20 = 20

Add 20 to each side

2x-20 +20 = 20+20

2x = 40

Divide by 2

2x/2 = 40/2

x = 20

Answer:

B' (16,14)

Step-by-step explanation:

Find the coordinates of the vertex B.

M is the midpoint of the diagonal AC.

A(2,7) and C(8,1), the center has coordinates Point M which is the midpoint of the diagonal BD.

Let B has coordinates (x,y),

B(8,7).

(x,y)→(2x,2y)

B(8,7)→B'(16,14).

Answer:

(16, 14)

Step-by-step explanation:

If there was no dilation, the fourth coordinate would be (8, 7)

Dilation of 2: (2x, 2y)

(16, 14)

Answer:

See attachment below

Step-by-step explanation:

For the first option, we are given m = - 2 / 3, b = 3. This is likely in the point - slope form y = mx + b, where m = slope and b = y - intercept. Thus, the equation of the line in point - slope form given this information, should be y = - 2 / 3x + 3. It seems as if none of the following equations match this form, so let us interchange the equation a bit,

y = - 2 / 3x + 3,

y + 2 / 3x = 3,

2x + 3y = 9 - Option C

_______________________________________________________

Next we are given m = - 3 / 2, and that this line passes through the point ( 4, - 1 ). Substitute m as - 3 / 2, x as 4, y as - 1, knowing point ( 4, - 1 ), into the form y = mx + b - solving for b.

- 1 = ( - 3 / 2 )( 4 ) + b,

b = 5,

Thus the equation in point - slope form should be y = - 3 / 2x + 5. None of the choices match this, so let us again alter the equation,

y = - 3 / 2x + 5,

2y = - 3x + 10,

- 2y = 3x - 10 - Option A

_______________________________________________________

( 6, 3 ) and ( 3, 1 ) is given to lie on this line. The slope of the line should be as follows,

Slope = 3 - 1 / 6 - 3 = 2 / 3

Now let us determine the y - intercept ( b ) by substitute one of the points, say ( 6, 3 ). In this case x = 6, and y = 3,

3 = ( 2 / 3 )( 6 ) + b,

b = - 1,

y = 2 / 3x - 1 = Option D

Answer:f(4)=1/2

f(x)=4 when x is 8

The complete statements would be as:

⇒ function f(4) is 1/2 and function f(x) = 4 when domain x is 8.

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

We have been given that the mapping diagram shows a functional relationship.

To determine the value of f(4)

As per the given functional relationship,

If the value of the domain is 4 then the value of the respective range would be 1/2.

Therefore, the function f(4) would be 1/2.

To determine the value of x,  when f(x) = 4

As per the given functional relationship,

If the value of the range is 4 then the value of the respective domain would be 8.

Therefore, x would be 8 if function f(x) = 4 .

Hence, the complete statements would be as:

f(4) is 1/2 and f(x) = 4 when x is 8.

Answer:

The largest possible number of overseas visitors would be 11,640,000.

The smallest possible number of overseas visitors would be 11,550,000.

Step-by-step explanation:

The number 11,600,000 was rounded off to the nearest 100,000.

This means that either 0 or 1 was added to the figure with place value of 100,000.

It would be zero (0) in the case where the number after the 100,000th placed value number is lower than 5 and it would be one (1) in the case where the number after the 100,000th placed value is greater than or equal to 5.

Therefore, the largest possible number of overseas visitors would be 11,640,000.

The smallest possible number of overseas visitors would be 11,550,000.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the expression   [tex]\sqrt{-16} - \sqrt{-3} \sqrt{-3} -\sqrt{-4} \sqrt{-4}+3i-3i^{2} +3i^{3}[/tex]

On simplifying;

First we need to note that i² = -1 and √-1 = i

Substituting the values in the expression, it becomes;

= √16(√-1)-√(-3)(-3)-√(-4)(-4)+3i-3(-1)+3i(i²)

= 4i-√9-√16+3i+3-3i

= 4i-3-4+3

= 4i-4

= 4(i-1)

Answer:

see below

Step-by-step explanation:

vanilla = 4 dollars per packet

chocolate = 1 dollar per packet

v = number of vanilla packets

c = number of chocolate packets

v+c = 27  for a total of 27 packets

4v+1c = 45  for 45 dollars spent

Subtract the first equation from the second equation  ( eliminate c to find v)

Since both equations have a coefficient of 1 for c, we can easily subtract to eliminate the c variable

4v + c =45

-v -c = -27

-------------------------

3v = 18

Divide by 3

3v/3 = 18/3

v = 6

6 packets of vanilla

Now find c

v+c = 27

6+c = 27

c = 27-6

c = 21

21 packets of chocolate

Answer:

Proved: <3 =<4

Step-by-step explanation:

Alternate angles are equal

<1 = <4

<2 = <3

AC ≅ AR (Given)

Where ≅ means congruent to

When two straight lines intersect, the Vertical angles have opposite sides that are equal.

<CAR ≅ <TAD

<CAT ≅ <RAD

From the above

∆CAR is congruent to ∆TAD

This is a side angle side theorem

∆CAT is congruent to ∆RAD

This is a side angle side theorem

The side angle side theorem shows that two sides and an included angle of one triangle are equal to two sides and an included angle of another triangle.

Since corresponding parts of congruent angles are equal, <3 is congruent to <4.

<3 ≅ <4
