Answer: See Annex
z (max) = 190
x = 10
y = 20
Step-by-step explanation:
z = 5*x + 7*y to maximize
Subject to:
x + y ≤ 30
2*x + y ≤50
2*x - y ≥ 0
x≥= y ≥0
A y-intercept always has to have an x-value of 0 so the answer is D (the last option)
If c is the hypotenuse and b is the leg, then the third side (a):

If b and с are legs, then hypotenuse (a):
The current height of the bird is -16/3
The bird perched at a height of 15 feet
The bird dropped to a height of 61/3 feet when it saw a food
The current height can be calculated as follows
= 15 - 61/3
= 45-61/3
= -16/3
Hence the current height of the bird is -16/3
