Graph the solution set of x < –6.?

Question

Solve and graph the solution set.3x > with a line under it 7x + 20



I don't know how to do these problems

Answer 1

On a number line, shade the line to the left of: -6. Do not shade: -6, use an open circle or ')' to indicate -6 is excluded.

3x ≥ 7x + 20
0 ≥ 7x - 3x + 20
-20 ≥ 4x
-5 ≥ x
x ≤ -5.
Include: -5 in the shading of the number line, use a filled circle on: -5 or a ']'. Shade in the direction of the sign, the left.

Answer 2

this signifies that the 'x' coordinate tiers from 6 right down to 4.00000000000000000000000000001. It ought to not in any respect contact '4.0'. In words 'X is the set such that 'X' is interior the determination from more effective than '4' to and which includes '6'".

Answer 3

3x>7x+20
-4x^20

x<-5

Answer 4

-infinity -6 0 +infinity
now your solution for x<-6 is -infinity to -6.and you can write it as (-infinity,-6).
