3. Which of the following is a linear inequality in two variables?
a. 3x + 3 >2
b.4r < 7 - 3
c.y ≥ 2x
d.6s + 5 ≤ h​


Sagot :

Answer:

A

Example:

Solve x + 7 < 15

Solution:

x + 7 < 15

x + 7 – 7 < 15 – 7

x < 8

Inequalities Of The Form “x – a < b” or “x – a > b”

Example:

Solve x – 6 > 14

Solution:

x – 6 > 14

x – 6+ 6 > 14 + 6

x > 20

Example:

Solve the inequality x – 3 + 2 < 10

Solution:

x – 3 + 2 < 10

x – 1 < 10

x – 1 + 1 < 10 + 1

x < 11
