The lines shown below are parallel. If the green line has a slope of -2, what is the slope of the red line? A. 1/2 B. -1/2 C. 2 D. -2

Answers

Answer 1

Answer:

D, -2

Step-by-step explanation:

Hello! If two lines are parallels, it means they will never meet. This means that they have to be the same slope, because if one is even the slightest bit different, it will eventually touch the other line! A great website to understand visually, is Desmos! You can plot the lines and see for yourself if you're a visual learner!

Hope this helps! :)

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answer: conversion factor is just how much of it is in another unit

Step-by-step explanation:

for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.


Original rate (15 miles) x conversion factor (5280 feet are in a mile)

So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd

The answer is 3 but the conversion factor is 3ft 1 yard

Answer:

40

Step-by-step explanation:

70% of something is 28.

We'll use the variable x to hold our value. 70% can be written as 0.7. Rewriting our equation, we get:

0.7 * x = 28.

Lets divide 0.7 over. Our new equation is:

x = 28 / 0.7.

You get that x = 40.

70% of 40 = 28.

The answer is 40

$ ___________

Answers

Answer: Simon paid $13.55 for the snack.

Plz mark brainliest ;)

Answer:

$13.55

Step-by-step explanation:

ok, so we know that Amber earned $15.50 on saturday and then he spet $6.95 on a movie ticket. so now we need to subtract $6.95 from his orgininal amount which was $15.50.

so $15.50 - $6.95 = $8.55

and then it says that he borrowed money from his friend to purchase a snack and that he now owes $5.00 to his friend so we add the amount of money he had plus the money he now owes his friend.

so $8.55 + $5.00 = $13.55

so in conclution, simon lent amber $5.00 and in total, they paid $13.55 for the snacks.

Hope that helps :)

A​ 168-yard-long field is divided into 12 parts of equal length. Mr. Gump paints a​ 6-yard-long strip in each part. How long is the unpainted strip in each part of the​ field?

Answers

Answer:8 Yards

Step-by-step explanation:

168/12=14 yards long.

14-6=8

The unpainted strip is 8 yards long.

Answer:

The unpainted strip in each part of the​ field is 8-yards-long

Step-by-step explanation:

168 divided into 12 equal parts would be: 168/12=14

and a 6-yard-long strip in each of those 14 parts would leave 8 yards unpainted in each of the 14 strips: 14-6=8

D would equal 19. First, you combine like terms, so add -1 and 105 together to get 104. Then you have to subtract 104 from both sides. After that you get 76 on the right side. Then you would have to divide 4 from both sides to get d by itself. Lastly, 76 divided by 4 is 19.

Answers

Answer:

50/3

Step-by-step explanation:

area of triangle = 10

area of circle = 10

area of triangle + area of circle = 20

The white sector of the circle has central angle 60°.

Its area is 1/6 the area of the circle.

To find the gray area, you must subtract the white area from the area of the circle and also subtract the white area from the area of the triangle. Two times the white area is 1/3 the area of the circle.

gray area = 20 - (1/3)10

gray area = 20 - 10/3

gray area = 60/3 - 10/3

gray area = 50/3

Answer:

The white sector of the circle = (1/6) (10) = 10/6 = 5/3

So....the grey area = 10 + 10 - 2 (5/3) = 20 - 10/3 = 60/3 - 10/3 = 50 / 3

Find an ordered pair , x y that is a solution to the equation. 5x-y=9

Answers

Answer:

(1, -4)

Step-by-step explanation:

In order to find a solution to a linear equation, we can substitute any value for one variable, simplify the equation, and find the value of the other variable to find a solution that is an ordered pair.  

Since any value for either variable will do, we can choose something simple, such as 1. I chose to substitute 1 for x into the equation, as seen below.  

\(5x-y = 9\\5(1)-y = 9\)

Now, all I need to do is solve and isolate y:

\(5(1)-y = 9\\5-y = 9\\-y = 4\\y =-4\)

So, with this linear equation, when x equals 1, y equals -4. Thus, a solution to the equation is (1, -4).
