Answer:
This system of equations has infinite points of intersection
Step-by-step explanation:
* To know the point of intersection of the system of equations,
you will solve the graphically or algebraically
- Graphically by drawing two lines on the coordinate plane
- Algebraically by substitution method or elimination method
* Lets use the substitution method
∵ y = 4 - x
∵ 2y = 8 - 2x
- Substitute y in the second equation by its value in the
first equation
∴ 2(4 - x) = 8 - 2x ⇒ open the bracket
∴ 8 - 2x = 8 - 2x
* The two sides equal each other, that means we can use any
vales of x, and on the graph they will be the same line for
the two equations
∴ This system of equations has infinite points of intersection
Answer:
well the money doubles every 6 years but its only been 4 so

Answer:
least value of n is 9
Step-by-step explanation:
Mary has n sheep. Then she buys 17 extra sheeps.
Mray = n + 17 sheeps
Sam had exactly 4 times as mary. Then Sam sold 8 of his sheep.
Sam = 4n - 8 sheep.
Sam has more sheep than Mary
Sam sheep is greater than Mary
4n - 8 > n + 17
Collect like terms
4n - n > 17 + 8
3n > 25
Divide both sides by 3
n > 25/3
n > 8.3333
Note: the value of n must be whole
Therefore, least value of n is 9
