Smallest to largest 0.8 30% 3/5

rjkz [21]

Change everything to the same thing. See like how 30% is a percent you can move the decimal of 0.8 to make it a percent like 80%, then for 3/5 you divide 3 by 5 and you get 0.6 then you can move the decimal to get 60%. So all you have to do now is order the percentages from smallest to largest. Like so 30%, 60%, 80% which then ends up as 30%, 3/5, 0.8.

Answer:

slope = 3/2
y-intercept = 3
x-intercept = -2

Step-by-step explanation:

The slope is the coefficient of x when the equation is of the form ...

y = (something).

Here, we can put the equation in that form by subtracting 12x and dividing by the coefficient of y:

12x -8y = -24 . . . . . given

-8y = -12x -24 . . . . .subtract 12x

y = 3/2x +3 . . . . . . . divide by -8

This is the "slope-intercept" form of the equation. Generically, it is written ...

y = mx + b . . . . . . where m is the slope and b is the y-intercept

So, the above equation answers two of your questions:

slope = 3/2

y-intercept = 3

The x-intercept is found fairly easily from the original equation by setting y=0:

12x = -24

x = -24/12 = -2 . . . . . the x-intercept

_____

A graph of the equation can also show you these things. The graph shows a rise of 3 units for a run of 2, so the slope is rise/run = 3/2. The line crosses the axes at x=-2 and y=3, the intercepts.
