Question
2z+3.7≥13.9−4z2𝑧+3.7≥13.9−4𝑧Step 1 of 2 : Write the solution using interval notation.
Solution
First, let's simplify the inequality:
2z + 3.7 ≥ 13.9 - 4z
We can start by adding 4z to both sides of the inequality to get:
2z + 4z + 3.7 ≥ 13.9
This simplifies to:
6z + 3.7 ≥ 13.9
Next, subtract 3.7 from both sides of the inequality:
6z ≥ 10.2
Finally, divide both sides by 6 to solve for z:
z ≥ 1.7
In interval notation, the solution is [1.7, ∞).
