Please try leaving out the "I'm so bad at math" part.  It doesn't help.

The given inequality is   <span>4x + y > −6.  Because of the > symbol, we must use a dashed line, not a solid one.  Let's solve this for y:    y > -4x - 6.

This (dashed) line has a slope of -4 and a y-intercept of (0,-6).

Plot (0,-6).  Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down.  Plot a new point there, at (1, -10).  Draw your dashed line thru those 2 pts.  Then, because we have y > -4x - 6, shade the area ABOVE this line.  Done.</span>

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).

which of the functions have a range of real numbers greater than or equal to 1 or less than or equal to-1​
lilavasa [31]

The question is incomplete. Here is the complete question:

Which of the functions have a range of all real numbers greater than or equal to 1 or less than or equal to -1? check all that apply.

A. y=\sec x

B. y= \tan x

C. y= \cot x

D. y= \csc x

Answer:

A. y=\sec x

D. y=\csc x

Step-by-step explanation:

Given:

The range is greater than or equal to 1 or less than or equal to -1.

The given choices are:

Choice A: y=\sec x

We know that, the \sec x=\frac{1}{\cos x}

The range of \cos x is from -1 to 1 given as [-1, 1]. So,

|\cos x|\leq 1\\\textrm{Taking reciprocal, the inequality sign changes}\\\frac{1}{|\cos x|}\geq 1\\|\sec x|\geq 1

Therefore, on removing the absolute sign, we rewrite the secant function as:

\sec x\leq -1\ or\ \sec x\geq 1\\

Therefore, the range of y=\sec x is all real numbers greater than or equal to 1 or less than or equal to-1​.

Choice B: y= \tan x

We know that, the range of tangent function is all real numbers. So, choice B is incorrect.

Choice C: y= \cot x

We know that, the range of cotangent function is all real numbers. So, choice C is incorrect.

Choice D: y=\csc x

We know that, the \csc x=\frac{1}{\sin x}

The range of \sin x is from -1 to 1 given as [-1, 1]. So,

|\sin x|\leq 1\\\textrm{Taking reciprocal, the inequality sign changes}\\\frac{1}{|\sin x|}\geq 1\\|\csc x|\geq 1

Therefore, on removing the absolute sign, we rewrite the cosecant function as:

\csc x\leq -1\ or\ \csc x\geq 1\\

Therefore, the range of y=\csc x is all real numbers greater than or equal to 1 or less than or equal to-1​.
