y = -|x + 4|
The coordinates of vertex of that function is (x; 0).
-|x + 4| = 0
|x + 4| = 0 ⇔ x + 4 = 0 |-4
x = -4
Answer: (-4; 0)

Problem 16
Divide both sides by 2 to undo the multiplication of 2 (done to the t).
2t > 324
2t/2 > 324/2
t > 162
Answer: t > 162
=====================================================
Problem 17
Similar to problem 16, we will divide both sides by 12
12y >= 1
12y/12 >= 1/12
y >= 1/12
Answer: y >= 1/12
Note: the symbol ">=" without quotes means "greater than or equal to".
=====================================================
Problem 18
To undo the division of 9.5, we multiply both sides by 9.5
x/9.5 < 11
9.5*x/9.5 < 9.5*11
x < 104.5
Answer: x < 104.5
Answer:
