The graph of a linear function has a y-intercept of 5 and passes through the point (2, 5). What is the slope of the graph of the function?

Answers

Answer:

Step-by-step explanation:2/5

The slope of the graph of function is 0

From the equation of the slope-intercept form of an equation of a straight line,

We have

y = mx +c

Where m is the slope

and c is the y-intercept

From the given information,

c = 5

and

The line passes through the point (2, 5)

∴ x = 2 and y = 5

Putting these values into the equation, we get

5 = m(2) + 5

5 = 2m + 5

5-5 = 2m

0 = 2m

∴ m = 0 ÷ 2

m = 0

Hence, the slope of the graph of function is 0

in how many year will rs 8000 amount to rs 13824 at 20% per annum interest compounded annually? please please help me out

Answers

Answer :-

3 years

step by step explanation:-

Let the time be x

principal = rs 8000

Amount = rs 13824

rate = 20% p.a

A = P(1+r/100)^n

13824 = 8000 ( 1 + 20/100)^n

=> 13824/8000 = (120/100)^n

=> 13824/8000 = (24/20)^n

=> (24/20)³ = (24/20)^n

=> 3 = n

=> n = 3 years

Answers

Answer:

1. y = -0.75x + 2

2. y = -1.8x - 7

3. y = -3x + 3

4. y = -11/7x + 56

5. y = -0.6x + 3

6. y = -2x - 14

7. y = 14x + 7

8. y = 2/8x - 4/3

9. y = x - 6

10. y = -1/3x + 4

Step-by-step explanation:

Question 1

3x + 4y = 8

4y = -3x + 8

y = -0.75x + 2

Question 2

9x + 35 = -5y

5y = -9x - 35

y = -1.8x - 7

Question 3

2y - 6 = -6x

2y = -6x + 6

y = -3x + 3

Question 4

-11x - 7y = -56

7y = -11x + 56

y = -11/7x + 56

Question 5

5y/3 = -(x - 5)

5y = -3(x - 5)

5y = -3x + 15

y = -0.6x + 3

Question 6

-2(2x + y) = 28

-4x - 2y = 28

2y = -4x - 28

y = -2x - 14

Question 7

-14x + y = 7

y = 14x + 7

Question 8

12y = (8x - 48)/3

36y = 8x - 48

y = 2/8x - 4/3

Question 9

(3x - 3y)/2 = 9

3x - 3y = 18

3y = 3x - 18

y = x - 6

Question 10

2x/3 + 4(y - 2) = 0

2x/3 + 2y - 8 = 0

2y - 8 = -2x/3

3(2y - 8) = -2x

6y - 24 = -2x

6y = -2x + 24

y = -1/3x + 4

x = 30 degrees because

all angles of a triangle = 180

6x = 180 divide by 6

x = 30

To make sure it’s right plug it in

x, 2x, 3x

30 + 2(30) +3(30) = 180

Some of these scholars made otherwise significant contributions to the world's knowledge of ancient Egypt. A German priest of the 1600s, Athanasius Kircher, wrote the first grammar and vocabulary of Coptic, the language of Christian Egypt.

Looking at a certain group of symbolswhich actually stood for the name of a pharaohKircher let his imagination run wild. Without any evidence to support him, he said that the hieroglyphs meant "The blessings of the god Osiris are to be procured by means of sacred ceremonies, in order that the benefits of the river Nile may be obtained."
