I need some help with this, please. The output of a function is 9 less than 10 times the input. Find the input when the output is 11.

Answer 1

Answer:

2

Step-by-step explanation:

10i -9 = 11

10i = 20

I = 2

Answer 2

So the equation is

• y=10x-9

Put y=11

• 10x-9=11
• 10x=11+9
• 10x=20
• x=2
