Mathematics
1 answer:
Verdich [7]2 years ago
7 0

Number Line:

Closed Circles are used when signs are "≤" or "≥"

Open Circles are used when signs are "<" or ">"

The graph of x > -1 on a number line would be towards the right from -1 with open circle as the sign is ">"

Graph should look like this:

PLEASE ANSWER WILL GIVE POINTS!!!!!!!!!!!!!
Gennadij [26K]

Answer:

1) 27.374

2)9.177

Step-by-step explanation:

1) To get the value of x , we use the appropriate trigonometric ratio

From what we are given;

we have the hypotenuse ( the side facing the right angle) and the adjacent

The trigonometric identity to use here is the cos

The cos of an angle is the ratio of the adjacent to the hypotenuse

cos 64 = 12/x

x = 12/cos 64

x = 27.374

2) Here, we are given the hypotenuse and the opposite

The trigonometric ratio to use here is the sine

the sine of an angle is the ratio of the opposite to the hypotenuse

thus, we have it that;

sin 35 = x/16

x = 16 sin 35

x = 9.177

Need Help Badly<br>What is the solution
Kamila [148]
Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8

The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign.

After doing this, we realize that only -1 works, so the answer is x=-1

Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:)

Best wishes:)
