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
Answer:
y=3x-9
Step-by-step explanation:
put into slope formula y2-y1/x2-x1 and then after finding the slope you put on the points into the equation y=3x+b and you find the b giving you the equation
Answer:
you have to use multiplication maybe division and addition
