Answer:

Option 4:  y > 2x

                x + 2y < -8

Step-by-step explanation:

Taking first equation:

y > 2x

Putting x = 0

y > 0

Putting y = 0

0 > x

So the blue line in drawn according to first equation.

Taking second equation:

 x + 2y < -8

Putting x = 0

 2y < -8

y < - 4

putting y = 0

 x < -8

So the red line is drawn accordingly.

i hope it will help you!

Help please ASAP please I’ll mark you as brainlister

Answer:

a = 4

Step-by-step explanation:

\sin(theta)  =  \frac{opposite}{hypotenuse}

\cos(theta)  =  \frac{adjacent}{hypotenuse}

\tan(theta)  =  \frac{opposite}{adjacent}

hypotenuse = a

opposite = 2√3

adjacent = b

theta = 60°

the best formula to use is the first formula cause we have all the values to substitute in it in order to find the value of a

\sin(60)  =  \frac{2 \sqrt{3} }{a}

\frac{2 \sqrt{3} }{ \sin(60) }  = a

4 = a

a = 4

What is the domain of the function y = log(x + 3)?
nata0808 [166]

Find the domain of

y = log(x + 3)

Logarithms can only be taken for positive numbers. So you must have

x + 3 > 0

x > – 3          ✔

So the domain of the function is

D = {x ∈ R:  x > – 3}

or using the interval notation

D = (– 3, +∞)


I hope this helps. =)
