What is the simplified expression of 5(3m+7) - 4?

Answer:

1. C' ( -12, 1 )

  B' ( -7, -2 )

2.

Original Coordinates = R ( -8, 4 )

                                      O ( -2, 4 )

                                      P ( -2 , 8 )

                                      E ( -8, 8 )

(A) Reflected (y = x)   = R ( 4, -8 )

                                     O ( 4, -2 )

                                     P ( 8, -2 )

                                     E ( 8, -8 )

(B) Reflected (y = -x)  = R ( -4, 8 )

(not sure if it's               O ( -4, 2 )

supposed to be after    P ( -8, 2 )

previous reflection)       E ( -8, 8 )

Step-by-step explanation:

1. C ( -6, 2 ) → ( -6 - 6, 2 -1 ) → ( -12, 1 )

  B ( -1, -1 ) → ( -1 - 6, -1 - 1 ) → ( -7, -2 )

2. Reflecting over y = x line --- ( x, y ) → ( y, x )

   Reflecting over y = -x line --- ( x, y ) → ( -y, -x )

Answer:

The y intercept is 5. Usually, this is the number that is by itself with no variable by it. Ex: y= 5x + 4. 4 would be the y intercept.

Value of [tex]p[/tex] is [tex]\frac{3}{2}[/tex]

In inverse variation, as one number increases, the other decreases and as one number decreases, the other increases.

That is [tex]xy=k[/tex] where [tex]k[/tex] is a constant.

Put values of [tex]x,y[/tex] as [tex]3,5[/tex] respectively.

[tex]3(5)=k[/tex]

  [tex]15=k[/tex]

So, [tex]xy=15[/tex]

Now put values of [tex]x,y[/tex] as [tex]10,p[/tex] respectively.

[tex]10p=15[/tex]

   [tex]p=\frac{15}{10}[/tex]

      [tex]=\frac{3}{2}[/tex]

Answer: 15 feet

Step-by-step explanation:

From the question, we are informed that a diving board is 10 feet above a pool. Since the ladder is 5 feet away from the base of the diving board, to calculate how tall is the ladder is, we subtract -5 from 10. This will be:

= 10 - (-5)

= 10 + 5

= 15 feet

The answer is option C.

Answer:

The answer is x = 1/11

Step-by-step explanation:

10x + 5x – 3 = 2(2x – 1)

10x+5x-3=4x-2

15x-4x=-2+3

11x=1

To find x divide both sides by 11

11x/11=1/11

x= 1/11

[tex]\frac{1}{11} or 0.0909090909090[/tex]

Add similar elements: 15x-3=2(2x-1)

Expand 2(2x-1): 4x-2

Add 3 to both sides

Simplify 15x=4x+1

Subtract 4x from both sides

Simplify 11x=1

Divide both sides by 11

Simplify [tex]\frac{1}{11} or 0.0909090909090[/tex]

Răspuns:

Apartament cu 2 camere = 8

Apartament cu 3 camere = 12

Explicație pas cu pas:

Dat fiind :

Numărul total de camere = 64

Numărul de apartamente = 20

Fie numărul de apartamente cu 2 camere = x

Numărul de apartamente cu 4 camere = y

2x + 4y = 64 - - (1)

x + y = 20 .-- (2)

De la (2);

x = 20 - y

2 (20 - y) + 4y = 64

40 - 2y + 4y = 64

2y = 64 - 40

2y = 24

y = 12

x = 20 - y

x = 20 - 12

x = 8

Apartament cu 2 camere = 8

Apartament cu 3 camere = 12

Answer: 12 degrees

Step-by-step explanation:

hopes this helps :)

The measure of the acute or right angle formed by intersecting lines so that C can be mapped to C' is equal to 12°.

What is an acute angle ?

Acute angles are those that are smaller than 90 degrees in length. This angle is less than right angle, which is of 90 degrees.

In order to map C to C' using two reflections, it is assumed that intersecting lines form an acute or right angle.

Therefore, in this case, we will apply the "reflection in intersecting line theorem."

A reflection in line k followed by a reflection in line m is equivalent to a rotation about point P if lines k and m cross at point P. The rotational angle in this instance is 2x°, where x° is the measurement of the acute or right angle formed by lines k and m.

So , If the angle of rotation is 24°, then the reflection in intersecting lines theorem determines the measure of the acute or right angle generated by the intersecting lines, allowing C to be mapped to C' using two reflections and that is equal to :

= 24° / 2

= 12°

Therefore , the measure of the acute or right angle formed by intersecting lines so that C can be mapped to C' is equal to 12°.

Step-by-step explanation:

Distribute

(20m + 3) - 1(7m - 5)

(20m + 3) - 7m + 5

Eliminate redundant parentheses

(20m + 3) - 7m + 5

20m +  3 - 7m + 5

Add the Numbers

20m +  3 - 7m + 5

20m + 8 - 7m

Combine Like Terms

20m + 8 - 7m

13m + 8

Solution

13m + 8

The difference of the given equation i.e. (20m+3)-(7m-5)  should be considered as the 13m + 8.

Since the equation is (20m+3)-(7m-5)

So,

= 20m + 3 - 7m + 5

= 13m  + 8

Hence, The difference of the given equation i.e. (20m+3)-(7m-5)  should be considered as the 13m + 8.

X = 14

Step-by-step explanation:

30 = 5x + 2

25         60

multiply both sides by 60

1800/25 = 5x + 2

Multiply both sides by 25

1800 = 25 (5x + 2)

1800 = 125x + 50

  -50.            -50

1750 = 125x

divide both sides by 125

14 = x

Answer:

x=14

Step-by-step explanation:

Similar Shapes

Two figures that have the same shape are said to be similar.

If two figures are similar, the ratios of the lengths of their corresponding sides are equal.

We are given two similar shapes and the lengths of two corresponding sides:

25 corresponds to 30

60 corresponds to 5x+2

According to the definition:

[tex]\displaystyle \frac{5x+2}{60}=\frac{30}{25}[/tex]

Multiplying by 60*25:

[tex]25(5x+2)=60(30)[/tex]

Operating:

[tex]125x+50=1800[/tex]

Subtracting 50:

[tex]125x=1800-50=1750[/tex]

Dividing by 125:

[tex]x = 1750/125 =14[/tex]

x=14
