12x-39<9 and -4x+3<-6
gulaghasi [49]
Remember, you can do anything to an equation as long as you do it to both sides


and when multiply or divide by a negative in inequalities, flip the direction of the sign

12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4



-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4

Y=-1/5 x -3 please help me
hammer [34]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following equation:

y = - \frac {1} {5} x-3

So we have to:

The slope is:m = - \frac {1} {5}

The cut-off point with the y axis is:b = -3

Answer:

The slope is: m =- \frac {1} {5}

The cut-off point with the y axis is: b = -3
