What is the slope of the line?

Answers

Answer:

Step-by-step explanation:

by inspection.. ( looking at the graph) we can see that the slope is down hill. so it's going to be negative and also slope = rise / run [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me (-3,1) and (2,-3) you tell me if that looks right... if it does .. then the rise / run is 4/5 and this is a negative slope sooo

- 4/5

What is the slope of line P? And then what is the slope of line Q?

Answers

Slope of p = 3
Slope of q = -3

P= 3/1
Q= -3/1
Rise over run q is going to the left so it’s negative

4. Sin N =

Answers

Answer:

[tex]\sin L = 0.60[/tex]

[tex]tan\ N = 1.33[/tex]

[tex]\cos L = 0.80[/tex]

[tex]\sin N = 0.80[/tex]

Step-by-step explanation:

Given

See attachment

From the attachment, we have:

[tex]MN = 6[/tex]

[tex]LN = 10[/tex]

First, we need to calculate length LM,

Using Pythagoras theorem:

[tex]LN^2 = MN^2 + LM^2[/tex]

[tex]10^2 = 6^2 + LM^2[/tex]

[tex]100 = 36 + LM^2[/tex]

Collect Like Terms

[tex]LM^2 = 100 - 36[/tex]

[tex]LM^2 = 64[/tex]

[tex]LM = 8[/tex]

Solving (a): [tex]\sin L[/tex]

[tex]\sin L = \frac{Opposite}{Hypotenuse}[/tex]

[tex]\sin L = \frac{MN}{LN}[/tex]

Substitute values for MN and LN

[tex]\sin L = \frac{6}{10}[/tex]

[tex]\sin L = 0.60[/tex]

Solving (b): [tex]tan\ N[/tex]

[tex]tan\ N = \frac{Opposite}{Adjacent}[/tex]

[tex]tan\ N = \frac{LM}{MN}[/tex]

Substitute values for LM and MN

[tex]tan\ N = \frac{8}{6}[/tex]

[tex]tan\ N = 1.33[/tex]

Solving (c): [tex]\cos L[/tex]

[tex]\cos L = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos L = \frac{LM}{LN}[/tex]

Substitute values for LN and LM

[tex]\cos L = \frac{8}{10}[/tex]

[tex]\cos L = 0.80[/tex]

Solving (d): [tex]\sin N[/tex]

[tex]\sin N = \frac{Opposite}{Hypotenuse}[/tex]

[tex]\sin N = \frac{LM}{LN}[/tex]

Substitute values for LM and LN

[tex]\sin N = \frac{8}{10}[/tex]

[tex]\sin N = 0.80[/tex]

What the answer

Answers

Answer:

x = 4.5 AND x = -4

Step-by-step explanation:

for the first answer

add 9 to 0 and divide by 2

for the second answer

subtract 4

Answer:

x = 9/2 and x = -4

Step-by-step explanation:

you can set each expression in the parenthesis' equal to zero. this is due to it being multiplication so if one parenthesis equals 0, the answer will be 0

2x - 9 = 0 and x + 4 = 0

starting with 2x-9=0

add 9 to both sides

2x = 9

divide by 2

x = 9/2

then do x + 4 = 0

subtract 4

x = -4

so your two answers are

x = 9/2 and x = -4

Answers

Answer:

x=60

Step-by-step explanation:

The sum of interior angles of a regular Pentagon is 540°

x+2x+2.5x+x+10+2x+20=540

8.5x=540-30

8.5x=510

x=510/8.5=60

Answer:

x = 60°

Step-by-step explanation:

Sum of interior angles of a regular polygon is:

180°(n-2)

Pentagon has 5 sides, so sum of angles is:

180°(5-2) = 180°*3 = 540°

For the given pentagon we have sum of angle measures as below, and solving for x:

x + 2x + 2.5x + (x +10) + (2x + 20) = 540°8.5x + 30° = 540°8.5x = 510°x = 510°/8.5x = 60°

Mary uses 212 cups of lemonade concentrate to make 20 servings of lemonade. How many servings can Mary make using 1 gallon of lemonade concentrate? Please include an explanation :)

Answers

Answer:

number of servings = 1.5

Step-by-step explanation:

1 gallon = 16 Cups

cups of lemonade concentrate : lemonade servings

212 cups : 20 servings

How many servings can Mary make using 1 gallon of lemonade concentrate

Let

x = number of servings

cups of lemonade concentrate : lemonade servings

16 cups : x servings

Equate both ratios to get x

212 : 20 = 16 : x

212 / 20 = 16 / x

Cross product

212 * x = 20 * 16

212x = 320

x = 320 / 212

= 1.5094339622641

Why do you add 6+4 first Pablo Picasso Pablo Picasso was a famous Spanish artist. To most, he is known simply as Picasso. He was born on October 25th, 1881, and died on April 8, 1973. Pablos father was a drawing teacher, and he encouraged his sons artistic ability. When Pablo was ten years old, the family moved to Barcelona, Spain, where Pablo took an exam to enter a famous and prestigious art school, called La Llonga. The exam was supposed to take one month, but Pablo finished it in one day! He later moved to Paris, where was worked as an artist creating and exhibiting his drawings. During this time, he created his famous Blue Period works. They were called this because of their devotion to the color, and because they were quite somber in nature. In 1907, Picasso painted Les Demoiselles dAvignon, which is known to have been the first painting in the modern art movement. Artists from all over the world travelled to see this painting. Picasso created cubism, with a colleague named George Braque In the 1920s, Picasso continued his work by creating theatre sets. His work during this period was considered neo-classical, modern, surreal, and cubist. In 1937, there was a terrible bombing in a small Spanish town called Guernica. Picasso reacted by creating one of his most famous murals, a masterpiece named after the town of Guernica. Picasso then moved on to print making and lithography. He was never content to use a medium the way it was traditionally used, and came up with many inventive new ways to create art. He worked on etchings, engravings, and worked on many other techniques. Just before his 87th birthday, he completed a series called the 347 Series, in which he created three hundred and forty seven pieces of etching and engraving work between March and October! One of the most interesting things about Picasso is that he was the first artist to be famous during his own lifetime. He was quite a celebrity, and is considered one of the most important artists of the twentieth century. WILL MARK YOU BRAINLIEST!!!!! 35 POINTSDaily communication is an essential part of our lives.
