Write the slope-intercept form of the equation of each line.
12x - 11y= 18

y=+

Step-by-step explanation:

What you do first is you move the 12x to the other side of the equation to get

-11y=18-12x

Move the 12x to the front to get the slope intercept form set up

-11y=-12x+18

Then divide the whole thing by -11 to get the y to become by itself

y=+

The 12/11 will become positive and the b value will become negative

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
