Carlotta subscribes to the HotBurn music service. She can download no more than 12 song files per week. Carlotta has already dow
UNO [17]

Answer:

Inequality: x+10\leq 12

Inequality solved: x\leq 2

The graph is attached.

Step-by-step explanation:

You need to remember the meaning of the inequalities symbols:

: Less than.

> : Greater than.

\leq : Less than or equal to.

\geq : Greater than or equal to.

Let be "x" the number of more songs Carlotta can download.

According to the information given in the exercise, she can download no more than 12 song files per week. This indicates that you must use the symbol \leq.

Since she has already downloaded 10 song files this week, you can write the following inequality that represents this situation:

x+10\leq 12

In order to solve it, you must subtract 10 from both sides:

x+10-10\leq 12-10\\\\x\leq 2

Plot this result on a number line.

Since the symbol of the inequality is \leq, the dot must be filled (Observe the number line attached).

Drag and drop each pair of lines to categorize them as either parallel, perpendicular, or neither.
miss Akunina [59]
Answer:
first box is parallel
Second box perpendicular
Third box neither
Fourth box neither
Fifth box perpendicular
Sixth box is parallel

Why? Slopes of parallel lines are the same. Slopes of perpendicular lines are opposite reciprocals. (Example slope=1/2 a perpendicular line would be -2/1). Neither is just a when it’s not either parallel or perpendicular.

Hope this helps
