D = 9 -48 = - 39 so the discriminant is less than zero so this mean that have not real roots 

x_1,2 = (3 +/- isqrt39)/4

hope this will help you

I really think it is 10/3, you can't simplify it any more so I think that that is the answer

Solve the equation. 8x2 – 4 = 28
Flura [38]
Hello,

Your answer would be 2, -2.

8x^2 - 4 = 28

8x^2-4+4=28+4

8x^2 = 32

\frac{8x^2}{8}=  \frac{32}{8}  


x^2 = 4

x = +/4 

x = 2 or x = -2

2 , -2 would be the answer! :)

What is the range of y = –3sin(x) – 4?
nydimaria [60]

Answer:

The required range of the function y=-3\sin (x)-4 is [-7,-1]

Step-by-step explanation:

Given : Function y=-3\sin (x)-4

To find : What is the range of the given function?

Solution :

The range is defined as the variation in which any function is defined.

We know that the sin function lies between [-1,1]

-1\leq \sin x\leq 1  .....(1)

The required function is y=-3\sin (x)-4

Multiply equation (1) by -3

-3\leq -3\sin x\leq 3  .....(2)

Now, we subtract equation (2) by 4

-3-4\leq -3\sin x-4\leq 3-4  

-7\leq -3\sin x-4\leq -1  

Therefore, The required range of the function y=-3\sin (x)-4 is [-7,-1].
