Answer:
y ≤ +
.
Step-by-step explanation:
Given : Graph .
To find : Which linear inequality is represented by the graph.
Solution : We have given graph with shaded down and solid line
It has solid line it mean inequality has equal to sign.
It is shaded down it mean inequality y has less than or equal to sign.
Slope = .
Slope = .
Slope = .
Y intercept = 0.2 = .
y intercept = .
Equation of line y = mx + b
Where m = slope , b = y intercept .
Plug the values of slope and y intercept .
y ≤ +
.
Therefore, y ≤ +

Answer:
x - 2, if x > 5
Step-by-step explanation:
The vertical lines either side of the expression mean absolute value.
The absolute value of a number is its <u>positive numerical value</u>.
if x > 5 then as 5 > 2, the values inside the vertical lines will always be positive. Therefore, we can disregard the absolute value.
Therefore:
x - 2, if x > 5
To find the range (output values) of the expression, substitute x = 5 into the expression:
⇒ 5 - 2 = 3
Therefore, |x - 2| > 3, if x > 5
