Question

write four solutions of y= 4X2 x​

Answer 1

Answer:

Step-by-step explanation:

)2x+y=9⟹y=9−2x

      x=1 then y=9−2(1)=7

       x=0 then y=9−2(0)=9

       x=2  then y=9−2(2)=5

       x=3   then y=9−2(3)=3

 (0,9),(1,7),(2,5),(3,3) are four solutions

2)xy+y=9⟹y=  

x+1

9

​  

 

      x=0 then y=  

0+1

9

​  

=9

      x=1  then y=  

1+1

9

​  

=4.5

       x=2 then y=  

1+2

9

​  

=3

       x=8  then y=  

1+8

9

​  

=1

(0,9),(1,4.5),(2,3),(8,1) are four solutions

3)x=4y

   y=0  then x=0

   y=1   then x=4

   y=2  then x=8

   y=3  then x=12

(0,0),(4,1),(8,2),(12,3) are four solutions

Answer 2

Answer:

1. 16=16

2. 8=8

3. 4=4

4. 24=24

Step-by-step explanation:

1. x=2

y=16

2. x=1

y=8

3. x=0.5

y=4

4. x=3

y=24
