Answer: y = x - 5
Step-by-step explanation:
Slope intercept form is y = mx + b
to find the slope: y2-y1/x2-x1: 15-14/20-19 = 1/1 = 1
so we can write it as y = x + b, (since the slope is 1).
To find b, plug in either point given to the formula:
15 = 20 + b
b = 15 - 20
b = -5
so the completed equation is y = x - 5
Answer:
y = x-5
Step-by-step explanation:
The form of slope intercept is y=mx+b]
To solve :
First you need to find the slope
To find the slope, you the slope equation, which is y2-y1/x2-x1
Since first you put y2-y1 at the top, it would be 14-15 and then 19-20 at the bottom since x2-x1 is put at the bottom.
Your slope equation should be : m=14-15/19-20, which should give you m=-1/-1 with m being 1.
Then you plug in the value in the slope intercept equation
To help us find the y intercepts, lets choose one our points. In this case, we will be using (20,15) since it is the first point.
Slope intercept form is y=mx+b.
we do 15= 1 x 20 +b
15=20+b, gives you b=-5
How you got b=-5:
1)Put the equation into this by switching sides :
1 (20)+b=15
2) Get rid of the parenthases :
1 x 20 + b=15
3) multiply :
1 x 20=20, so
20+b=15
4) On both sides, subtract 20
so it would be
20+b-20=15-20, which gives you b=-5
Find the area of the shaded region, thank you!
Answer:
5.1 cm² (nearest tenth)
Step-by-step explanation:
[tex]\mathsf{area\ of \ sector=\dfrac{\theta\pi r^2}{360} \ (where\ \theta \ is \ measured \ in \ degrees)}[/tex]
Given:
r = 5[tex]\theta[/tex] = 80°[tex]\implies \mathsf{area\ of \ sector=\dfrac{80 \cdot\pi\cdot 5^2}{360}=\dfrac{50}{9}\pi \ cm^2}[/tex]
[tex]\mathsf{area\ of \ triangle=\dfrac12 ab\sin C}[/tex]
Given:
a = 5b = 5C = 80°[tex]\implies \mathsf{area\ of \ triangle=\dfrac12 \cdot 5 \cdot 5\sin (80)=\dfrac{25}{2}\sin(80) \ cm^2}[/tex]
Area of shaded area = area of sector - area of triangle
[tex]\implies \mathsf{area=\dfrac{50}{9}\pi-\dfrac{25}{2}\sin(80)}[/tex]
Therefore, area = 5.1 cm² (nearest tenth)
I think of a number and I divide it by 3. I multiply it to the sum of 4 and 5. The
answer is 81. What is the number?
aswer it pls
Answer:
27
Step-by-step explanation:
Let the number be x
x/3 * (4 + 5) = 81
x/3 * 9 = 81
x/3 = 81/9 = 9
x = 3 * 9 = 27
Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V?
So
[tex]\\ \rm\hookrightarrow P(E)=\dfrac{|E|}{|S|}[/tex]
[tex]\\ \rm\hookrightarrow P(E)=250/500=1/2=0.5[/tex]
7/25=0.3Second bag is more preferable
Answer:
Bag 1
Probability of picking a V = P(V) = 7/25 = 0.28
Bag 2
Probability of picking a V = P(V) = 250/500 = 1/2 = 0.5
You are more likely to pick a tile that is the letter V from Bag 2 since 0.5 > 0.28

solve. 3 is less than y minus 2
Answer:
[tex]\bold{3 < (y - 2)} \\ \bold{y > 3 + 2} \\\bold{ y > 5}[/tex]
hope helpful~
Answer:
3 is less than y minus 2 => 3 < y - 2
Step-by-step explanation:
If an expression has an equal sign, it is called an equation.
If it has less than or greater than sign, then it is called inequality.
It is also an inequality if it has greater than or equal to or less than or equal to signs. ( ≥, ≤).
Now y minus 2 means
y - 2
Now it says 3 is less than (y-2)
So we get
3 < y - 2

What is the amplitude of this function f(x) ?
f(x)=34cos(3x)+4
Enter your answer in the box.
The comparison between the standard form of the cosine and f(x)=34cos(3x)+4 shows that the amplitude of the function given is 34.
Cosine Functions
The standard form of the cosine is given by:
y=acos(bx+c)+d
where:
a= amplitude - half the distance between the maximum and minimum values of the function. The value of a will be |a|.
b= the number of cycles the function completes in an interval of from 0 to 2π. This parameter influences in the period since is [tex]\frac{2\pi }{b}[/tex].
c= horizontal shift
d= vertical shift
The question asks the value of amplitude. Therefore, you should compare the standard form with equation function given.
Thus, you have:
y=acos(bx+c)+d
f(x)=34cos(3x)+4
The comparison shows: a=34, b=3, c=0 and d=4
Hence, the amplitude of the function f(x)=34cos(3x)+4 is equal to 34.

Ratio and proportions
Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:
0.2 of a book = 1.5 hours
In order to determine the time taken to read 0.75 part of the book, we will have:
0.75 of a book = x

What is the average of -2.5, 5.2, 1.7, and -0.8.
Answer:
0.9
Step-by-step explanation:
-2.5 + 5.2 + 1.7 + -0.8 = 3.6
Divide by the total count of numbers
= 0.9
Hope this helps!
Answer:
0.9
Step-by-step explanation:
To find the average or mean, you have to add up all the given numbers in your data set, then divide by how many numbers there are.
1. Add up -2.5 + 5.2 + 1.7 + (-0.8)=
(negative times positive equals negative)
simplify the signs
simplified answer= -2.5+5.2+1.7-0.8
Which equals
3.62. divide by how many numbers there are
So take 3.6 and divide it by 4.
why the number 4?
well, there are 4 numbers in the data set. so when you calculate the average, the formula would be to add up all the numbers in the data set and divide by how many numbers are in the data set and there are 4 numbers in the data set.
So... 3.6 divided by 4
is...
0.9The average is 0.9
