What is the equation of a line that goes through the point (0,2) and has a slope of -1 ?

1 answer:

8 0

Answer: A, because when x=1/-1 you don't need to write down the one meaning it is -x and then +2 is the y which means the full answer is y=-x+2

Does the relationship {(1,1), (2,1),(3,2), (4,3), (5,5), (6,8), (7,13)} represent a function?

storchak [24]

Answer:

Yes.

Step-by-step explanation:

A function is a set of relations without repetitive domains.

From the given relation, there are no repetitive domains. Thus our relation here is a function.

Example of Function

{(1,1), (2,2), (3,3), (4,4), (5,5)}

Example of Non-Function

{(1,1), (1,2), (2,3), (3,4), (4,5)}

From this relation, there are two repetitive domains which are 1's. Thus not making the relation a function.

HELP I NEED THIS BEFORE 1:09 PLEASE HELPPP

Answer:

C. 85 degrees

Step-by-step explanation:

(set the equations equal to each other):

6x-25 = 4x+15

(solve for x):

2x = 40

x = 20

(plug in x back into the equation):

6(20)-25 = 120-25 = 95

(subtract your value from 180 degrees (180 degrees is a line)):

180-95 = 85 degrees

[ Answer ]

$\boxed{=}$

[ Explanation ]

4 + 3 + 7 ___ 7 + 0 + 7

Solve Each Side:

4 + 3 + 7 = 14

7 + 0 + 7 = 14

14 __ 14

14 is equal to 14, therefore the __ (Or ?) is replaced with an = sign.

$\boxed{[ \ Eclipsed \ ]}$

Factor the trinomial x^2 - 7x + 10

Valentin [98]

Answer:

(x-5) (x-2)

Step-by-step explanation:

x^2 (-2x-5x) +10

basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
