Get the b all alone on one side of the inequality. To do this, we can divide both sides by 5.

5b / 5 ≤ -15 / 5
b ≤ -3

So, that means b has to be less than or equal to -3.

In interval notation it would look like [-3, -∞)

In a set builder notation: {x | x ∈ R, x ≤ -3}

Which is read as the set of all x, such that, x is a member of the real numbers and x is less than or equal to -3.

Answer:

QR ≈ 16.2 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan62° = \frac{opposite}{adjacent} = \frac{QR}{RP} = \frac{QR}{8.6} ( multiply both sides by 8.6 )

8.6 × tan62° = QR , then

QR ≈ 16.2 ft ( to the nearest tenth )
