Remember, irrational times rational=irrational
a rational number can be written as a/b where a and b are integers and b≠0
so
9.6 is a rational number betwen 9.5 and 9.7 because 9.6=96/10
an irrational number, hmm
let's use pi
pi is about 3.14
divide 9.5 by pi and 9.7 by pi
9.5/pi=3.0239
9.7/pi=3.0876
so an irrational number between 9.5 and 9.7 could be 3.05π
Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
Answer:
A(3,-5) abscissa:3 ordenada: -5
B(-1,0) abscissa: -1 ordenada: 0
C(-3,5;-2) abscissa: -3.5 ordenada -2
D(0,-1) abscisa: 0 ordenada:- 1
Step-by-step explanation:
What we must take into account is that the abscissa is the value of x and the ordinate is the value of y. There is always a number of the (x,y), that is, the abscissa is the first value and the ordinate is the second value, therefore:
