Answer:
(0,−2),(1,− 1/ 2 ), ( 2 , 4 )
Step-by-step explanation:
a + 2 a + 5 = b 3
Solve the equation for y .
Find the LCD of the terms in the equation.
3 ( a + 5 )
Multiply each term in
a + 2 a + 5 = b 3 by 3 ( a + 5 )
to eliminate the fractions.
3 a + 6 = b a + 5 b
Solve the equation.
a = 5 b − 6 3 − b
Choose any value for b that is in the domain to plug into the equation.
Choose 0 to substitute in for b to find the ordered pair.
Simplify
5 ( 0 ) − 6 3 − ( 0 ) .
a = − 2
Use the b and y values to form the ordered pair.
( 0 , − 2 )
Choose 1 to substitute in for b to find the ordered pair.
Simplify
5 ( 1 ) − 6 3 − ( 1 ) .
a = − 1 /2
Use the b and y values to form the ordered pair.
(1,−1/2)
Choose 2 to substitute in for b to find the ordered pair.
(2,4)
These are three possible solutions to the equation.
(0,−2),(1,− 1/ 2 ), ( 2 , 4 )
