>, ≥ - shaded region above a line
y = 3x
for x = 0 → y = 3(0) = 0 → (0, 0)
for x = 2 → y = 3(2) = 6 → (2, 6)
y < 3x - dotted line, shaded region below the line
y = 5 - it's a horizontal line passes througth points (x, 5) <em>/x - any real number/</em>
y < 5 - dotted line, shaded region below the line
Answer:
Step-by-step explanation:
12.9 + 10.2x = 35.1
10.2x = 35.1 - 12.9
10.2x = 22.2
x = 22.2/10.2
x= 222/102 = 111/51
