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
Larger = 2smaller + 1 ----(1)
smaller = 2 larger - 17 ----(2)
put (2) in (1)
larger = 2(2larger-17) + 1
larger = 4larger-34+1
-3larger = - 33
so larger= 11
then smaller= 2(11)-17 = 5
answer two integers are 11 and 5
I am not sure about the probability but I cant tell you these events are independent because u don't need to roll a five for a coin to land on heads
Answer:
312
To find the number that is 80% of 390, multiply 390 by 80%.
80% = 0.8.
390 * 0.8 = 312
