Oh, this is easy. For any prism, you find the surface area by finding the are of all the sides. I will post all surface area formulas here, for reference
Cube:
Surface area = 6 × a2
Right circular cylinder:
Surface area = 2 × pi × r2 + 2 × pi × r × h
pi = 3.14
h is the height
r is the radius
Rectangular prism:
Surface area = 2 × l × w + 2 × l × h + 2 × w × h
l is the length
w is the width
h is the height
Sphere:
Surface area = 4 × pi × r2
pi = 3.14
r is the radius
Right circular cone:
Surface area = pi × r2 + pi × r ×( √(h2 + r2))
pi = 3.14
r is the radius
h is the height
l is the slant height
Right square pyramid:
Surface area = s2 + 2 × s × l
s is the length of the base
h is the height
l is the slant height
A. NOT
(-5, 2) → x = -5, y = 2
y ≤ x - 5 → 2 ≤ -5 - 5 → 2 ≤ -10 FALSE
B. YES
(5, -2) → x = 5, y = -2
y ≤ x - 5 → -2 ≤ 5 - 5 → -2 ≤ 0 TRUE
y ≥ -x - 4 → -2 ≥ -5 - 4 → -2 ≥ -9 TRUE
C. NOT
(-5, -2) → x = -5, y = -2
y ≤ x - 5 → -2 ≤ -5 - 5 → -2 ≤ -10 FALSE
D. NOT
(5, 2) → x = 5, y = 2
y ≤ x - 5 → 2 ≤ 5 - 5 → 2 ≤ 0 FALSE
2x - 5y = 9
2x -9 = 5y
(2x -9) /5 = y
x= -1
(2(-1) -9)/5 =y
(-2 -9) / 5 = y
-11/5 = y
x=0
(0-9)/5 = y
-9/5 = y
x=1
(2(1) - 9) /5 = y
-7/5 = y
