9 less than the square root of a number
Ahat [919]

Answer:

\sqrt{x}-9

Step-by-step explanation:

Let's break it down. There is..

  • 9 less than
  • square root of a number

-----------------------------------------------------

A square root of a number: \sqrt{x} (assuming "the number" is x).

And they say that 9 is less than that, so we subtract 9 from \sqrt{x}, which gives us \sqrt{x}-9.

I hope that helps! :)

Y=-5x+30 7x+3y=42 1111
jekas [21]

Step-by-step explanation:

7x+3y=42.

y=-5x+30.

7x+3(-5x+30)=42

7x-15x+90=42

8x=42-90

-8x=-48

x=-48/-8

x=6

y=-5x+30

y=-5×6+30

=-30+30

y=0
