Y = 2x + 5
(7,1)...x = 7 and y = 1
now we sub
1 = 2(7) + 5
1 = 14 + 5
1 = 19...incorrect....NO (7,1) is not a solution
***now if there was a typo and ur set of points are (1,7)
y = 2x + 5
7 = 2(1) + 5
7 = 2 + 5
7 = 7...correct....so (1,7) is a solution
The distance between what?
Answer:
Linearly independent, x = 0
Step-by-step explanation:
- We are given three functions as follows:

- We are to determine the linear - independence of the given functions. We will use the theorem of linear independence which states that:

Where,
c1 , c2 , c3 are all zeroes then for all values of (x),
- The system of function is said to be linearly independent
- We will express are system of equations as such:
- To express our system of linear equations we will choose three arbitrary values of ( x ). We will choose, x = 0. then we have:

- Next choose x = 1:

- Next choose x = 2:

- Solve the last two equations simultaneously we have:
.... ( Only trivial solution exist )
Answer: The functions are linearly independent
- The only zero exist is x = 0.
Answer:
y=-15x+50
Step-by-step explanation:
You originally had 50 dollars, so +50. Then, it decreases at a rate of 15 every week, so -15x.
Y is the total number of money she has.
y= -15x+50
