4x−9≥−21 ?(1 point) Responses
as a graph
To graph the inequality 4x - 9 ≥ -21, we first need to isolate the variable x.
Adding 9 to both sides of the inequality:
4x - 9 + 9 ≥ -21 + 9
Simplifying:
4x ≥ -12
Dividing by 4 (since the coefficient of x is 4 and we want to isolate x):
x ≥ -3
Now, let's graph the inequality on a number line:
We plot a closed circle at -3 (since x is greater than or equal to -3) and draw a line to the right to represent all the values of x that are greater than -3.
