Point (3,2) lies on the line ax+2y = 10. Find a.

-2

Step-by-step explanation:

Using y=mx+c

ax+2y=10

Put y as subject of formula

2y= 10-ax

2y= -ax+10

using point (3,2)

2y= -ax+10

2(3)= -a(2)+10

6= -2a+10

Put a as subject of formula

-2a=10-6

-2a=4

a= 4/-2

a= -2

a=2

Step-by-step explanation:

a(3)+2(2)=10

3a+4=10

3a=6

a=2

hope this helps, have a great day

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
