Question

represent the function y=15+5y-x² for 0<x<7 using table.
Base on the table, using scale 2cm to 1m to the x axis and 2cm 5m on the y axis, draw a graph.
Help.​

Answer 1

Answer:

Correct option is

A

x=−1;y=3

3x+5y=12

⟹3x=12−5y

⟹x=

3

12−5y

Let, y=3, then x=

3

12−5(3)

=−1

Similarly,when y=0,x=4 and y=−6,x=6

3x−5y+18=0

⟹3x=−18+5y

⟹x=

3

−18+5y

Let, y=3, then x=

3

−18+5(3)

=−1

Similarly, when, y=0,x=−6 and y=6,x=4

∴ the intersecting point is x=−1,y=3
