Answer:
<em>-4 ≤ y ≤ 7</em>
Step-by-step explanation:
<u>Inequalities</u>
Solve the system of inequalities:
4y - 7 ≤ 3y [1]
3y ≤ 5y + 8 [2]
A.
Subtracting 3y to [1]:
y - 7 ≤ 0
Adding 7:
y ≤ 7
Subtracting 5y to [2]:
-2y ≤ 8
Dividing by -2 (and flipping the sign):
y ≥ -4
The solution of the system is all the values of y greater or equal to -4 and less or equal to 7.
B.
The solution can be expressed as:
-4 ≤ y ≤ 7
<h3>
Answer: Angle P (choice 4)</h3>
=======================================
The tangent of an angle is the ratio of the opposite over adjacent sides.
tan(angle) = opposite/adjacent
tan(theta) = 4/3
This means that
opposite = 4 and adjacent = 3
This only happens when angle P is the reference angle. In other words,
tan(P) = 4/3
