Answer:
-89 is rational
√101 is irrational
Step-by-step explanation:
An irrational number is a number that <u>cannot</u> be expressed as a fraction in terms of whole numbers.
-89 = -89/1 which is a fraction and is therefore rational
√101 does cannot be put into a fraction of whole numbers and is therefore irrational
Answer:
(1, 5 )
Step-by-step explanation:
Choose any value of x, substitute into the equation and solve for y
x = 1, then
4(1) + y = 9, that is
4 + y = 9 ( subtract 4 from both sides )
y = 5
Thus (1, 5 ) is a solution to the equation
The ordered pair (-1, 6) is the solution to the system of equations.
Step-by-step explanation:
Given equations are;
3x+2y=9 Eqn 1
y=4x+10 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
Dividing both sides by 11
Putting x=-1 in Eqn 2
Solution: (-1, 6)
The ordered pair (-1, 6) is the solution to the system of equations.
