Step-by-step explanation:

2y+3=15

2y=12

y=6

9 times 9=72

Step-by-step explanation:

if if the width is 9 then the length is 9 because 9 times 9 equals 72

Answer:

The length is 15

The width is 21

Step-by-step explanation:

Say the length of the rectangle is x.

Then, the width would be 2x-9.

You can use this to make the equation

x+x+2x-9+2x-9=72

6x-18=72

6x=90

x=15

2x-9=30-9=21

Therefore,

The length is 15

The width is 21

Example:

x^2 + 5x + 6 = 0

(x+3)(x+2) = 0 .... factor

x+3 = 0 or x+2 = 0 ... zero product property used here

x = -3 or x = -2 .... solve each equation for x

------

In general, the zero product property is that if A*B = 0, then either A = 0 or B = 0.

Answer:

a. –4(5x) = 12; OPEN

b. 4 x 6 = 24; TRUE

c. a + 4 = 6, when a = 2; TRUE

d. 4x = 19, when x equals 5; FALSE

Step-by-step explanation:

a. –4(5x) = 12 [-20x = 12 {Divide -20 from both sides} x = -0.6 So, if x is = -0.6, then it is true, so OPEN.

b. 4 x 6 = 24 [4 x 6 = 24 so TRUE]

c. a + 4 = 6, when a = 2. (Plug 2 in for a) 2 + 4 = 6; 6 = 6; TRUE

d. 4x = 19, when x equals 5. (Plug 5 in for x) 4(5) = 19; 20 is not = 19; FALSE

Answer:

50

Step-by-step explanation:

You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:

330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)

x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)

Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:

330x + 1220(17 - x) = 12730

330x + 20740 - 1220x = 12730

-890x + 20740 = 12730

-890x = -8010

x = 9

Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:

9 + y = 17

y = 8

Sarah bought y = 8 first class tickets.

Answer:

B.Economic growth

Step-by-step explanation:

per capita income can't be just improved by making a business successful

stable prices need a good income and that's not a point given in the question

Making business successful doesn't make all the citizens employed. so the most relevant answer is economic growth as grown business in a country provides tax and thus ensures the economic growth

Answer:

[tex]m=\frac{1}{6}[/tex] (Parallel)

[tex]m=-6[/tex] (Perpendicular)

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

[tex]m=\frac{-3-(-2)}{1-7}[/tex]

[tex]m=\frac{-3+2}{-6}[/tex]

[tex]m=\frac{-1}{-6}[/tex]

[tex]m=\frac{1}{6}[/tex]

A parallel line always has the same slope as the original.

[tex]m=\frac{1}{6}[/tex] (Original)

[tex]m=\frac{1}{6}[/tex] (Parallel)

A perpendicular line always has the negative reciprocal slope of the original.

[tex]m=\frac{1}{6}[/tex] (Original)

[tex]m=-6[/tex] (Perpendicular)

Answer:

The troposphere is the region that starts at Earth's surface and ends between 8 km and 20 km above Earth.

Step-by-step explanation:

66 degrees

Thing you have to know for these types of problems: The total measure of all angles is 180 degrees.

With that in mind, if we add 83 and 31, we get 114 degrees.

Now subtract from 180 and you will get 66 degrees.

Answer:   -7

The integer to the right is -6

See the diagram below.

Answer:

5 - (1 + 20) = yx

Step-by-step explanation:

So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

Answer:

  x = 72

Step-by-step explanation:

The sum of interior angles of a pentagon is (5-2)(180°) = 3·180°. The sum of the two right angles is 180°, so we can write the equation ...

  180° +2x° +x° +2x° = 3·180°

  5x = 2·180 = 360 . . . . divide by °, subtract 180

  x = 360/5 = 72 . . . . . . divide by 5

The value of x is 72.

Answer: the function y = cos(2x) - 2 and the function y = cos(x) - 3

Step-by-step explanation: just took it

Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].

The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:
