-4a is less than or equal to 6.5
The Subject Area looks like math? What is the "a" for in -4a? A minus number will be less than zero so what do you think?
Sra
-4a <or= 6.5
4a >or= -6.5
(The sign direction must switch when multiplying both sides by a negative number, -1). Now divide both sides by 4.
a >or= -1.625
To solve the inequality -4a ≤ 6.5, we need to isolate the variable "a" on one side of the inequality sign.
Step 1: Divide both sides of the inequality by -4, but note that when dividing by a negative number, we must reverse the inequality sign:
a ≥ 6.5 / -4
Step 2: Simplify the right side:
a ≥ -1.625
So, the solution to the inequality -4a ≤ 6.5 is a ≥ -1.625.
