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)

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:

-4

Step-by-step explanation:

4(-3)+2(4)=-4

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

Answer:

6.4 units

Step-by-step explanation:

c = √(x1 - x2)^2 + (y1 - y2)^2

c = √(3 - 7)^2 + (-3 + 8)^2

c = √(-4)^2 + (5)^2

c = √16 + 25

c = √41

c = 6.4031...

c = 6.4

Answer:

105°

Step-by-step explanation:

25+50+x=180

75+x=180

x=105

Answer:

Step-by-step explanation:

sum of interior angles = 180

25 + 50 + x = 180

x = 180 - 25 - 50

x = 105°

Answer:

The constant of proportionality is the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX. ... The constant of proportionality does is, the value of Y is dependent on how the given value of X is effected by the constant of proportionality.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Constant of proportionality means slope which can be represented as y=mx+b, y=kx and a ton of other stuff I don't know.

But lets take it as y=kx because it's easier. Constant of proportionality/slope is k so its C, 5.5.

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:

Step-by-step explanation:

Answer: 10

Step-by-step explanation:

The x-intercepts means when y equals 0, or when the function crosses the x-axis.

0 = (x-6)^2 - 16

16 = (x-6)^2

Take the square root of both sides:

4 = (x-6)

Add 6 to both sides to get:

x = 10

Answer:

A

Step-by-step explanation:

you can only +/- an equation like this with the same square root

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.
