To solve the inequality z + 1/8 > 1/5, we will subtract 1/8 from both sides of the inequality:
z + 1/8 - 1/8 > 1/5 - 1/8
This simplifies to:
z > 8/40 - 5/40
z > 3/40
So, the solution to the inequality z + 1/8 > 1/5 is z > 3/40.
To graph this inequality, we will represent it on a number line. Since z is greater than 3/40, we will represent it with an open circle at 3/40 and shade the line to the right, indicating all values greater than 3/40 are solutions to the inequality. The graph will look like:
--------●======================>
Where the open circle represents 3/40 and the line extending to the right indicates all values greater than 3/40.
Now moving to the second inequality, y + 7 ≤ 5.
To solve this inequality, we will subtract 7 from both sides of the inequality:
y + 7 - 7 ≤ 5 - 7
This simplifies to:
y ≤ -2
So, the solution to the inequality y + 7 ≤ 5 is y ≤ -2.
To graph this inequality, we will represent it on a number line. Since y is less than or equal to -2, we will represent it with a closed circle at -2 and shade the line to the left, indicating all values less than or equal to -2 are solutions to the inequality. The graph will look like:
<========●----------------
Where the closed circle represents -2 and the line extending to the left indicates all values less than or equal to -2.
To solve inequalities and graph the solutions, we need to follow a few steps:
For the inequality z + 1/8 > 1/5:
Step 1: Subtract 1/8 from both sides of the inequality to isolate the variable.
z + 1/8 - 1/8 > 1/5 - 1/8
z > 8/40 - 5/40
z > 3/40
Step 2: Simplify the result.
Step 3: Graph the solution on a number line. Since the inequality is "greater than," the graph will be an open circle at 3/40 and a shaded region to the right.

The correct solution is z > 3/40.
For the inequality y + 7 ≤ 5:
Step 1: Subtract 7 from both sides of the inequality.
y + 7 - 7 ≤ 5 - 7
y ≤ -2
Step 2: Simplify the result.
Step 3: Graph the solution on a number line. Since the inequality is "less than or equal to," the graph will be a closed circle at -2 and a shaded region to the left.

The correct solution is y ≤ -2.
