Which is the graph of 2x + 3y >-3?

Cerrena [4.2K]

Answer:

The third graph is correct for the inequality 2x + 3y > -3

Step-by-step explanation:

The slope of the graph is –2/3.

The y-intercept is –1

The area above the dashed be line is shaded.

To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.

For example: (1,1)

2(1) + 3(1) > –3

2 + 3 > –3

5 > –3 True.

Simplify please and show steps:<br><br> Sec (x) tan (x) csc (x) cot (x) sin (x) cos (x)

Airida [17]

Answer:

<h2>The answer is 1</h2>

Step-by-step explanation:

First of all transform the expression using trigonometric identities

That's

$\sec(x) = \frac{1}{ \cos(x) }$

$\csc(x ) = \frac{1}{ \sin(x) }$

$\cot(x) = \frac{1}{ \tan(x) }$

So we have

$\frac{1}{ \cos(x) } \times \tan(x) \times \frac{1}{ \sin(x) } \times \frac{1}{ \tan(x) } \times \sin(x) \times \cos(x)$

Reduce the expression with tan x

We have

$\frac{1}{ \cos(x) } \times \cos(x) \times \frac{1}{ \sin(x) } \times \sin(x)$

Reduce the expression with cos x

That's

$1 \times \frac{1}{ \sin(x) } \times \sin(x)$

Reduce the expression with sin x

We have

$1 \times 1$

We have the final answer as

Hope this helps you
