Question

Solve -3x + 1 > 4 and describe the graph of the solution.
x < -1; Open circle on -1, shading to the left
x < -1; Open circle on -1, shading to the right
x > -1; Open circle on -1, shading to the left
x > -1; Open circle on -1, shading to the right

Answer 1

stands for the number that -3 will be multiplyed by to get 6. As we both should know, to get a positive number out a negative, you have to multiply TWO negatives together to get a positive. so what will give you 6 when multiplyed by 3? -3(x)= 6. [ we know that 3 times 2 will give us 6. So, in order to make a positive six we will multiply -3(-2) which will give us 6. ]

Answer 2

x<-1, shading to the left

Answer 3

can u explain ?

Answer 4

the solution is x<-1, which means all points to the left of -1
the absence of equality makes it an open circle

Answer 5

okay thanks :)
