Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?
1 answer:
The option second "A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right" is correct.
<h3>What is inequality?</h3>It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
The options are attached in a picture please refer to the attached picture.
We have an inequality:
3(8 – 4x) < 6(x – 5)
After solving:
8 - 4x < 2(x - 5)
8 - 4x < 2x - 10
8 + 10 < 2x + 4x
18 < 6x
3 < x or
x > 3
x ∈ (3, ∞)
Thus, the option second "A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right" is correct.

Answer:
Reflection of point 0(x, y) about y-axis = (-x, y)
Step-by-step explanation:
Following are the rules for a counter clockwise rotation of 90 degrees about the origin for a point O(x,y):
1. Invert the sign of the value of x.
2. The value of y-coordinate remains the same.
For example, a point M(h,k) after reflection gives a point M'(-h,k) using the rules given above. The points on the x-y plane are shown in the image attached.
