Solve for x in the given interval.

Mathematics
1 answer:
Nat2105 [25]3 years ago
8 0

Answer:

7pi/2

Step-by-step explanation:

Given the expression cosec x = -1

I'm trigonometry csecx = 1/sinx

The equation becomes

1/sin(x) = -1

Sinx = -1

x = arcsin(-1)

x = -90°

x is negative in the third and 4th interval

Third interval;

x = 180+90

x = 270°

x = 3pi/2

Since the angle should be within 3pi < x < 4pi

Add 2pi to the angle

x = 2pi+ 3pi/2

x = 7pi/2

Hence the required angle is 7pi/2

If y=5-3 and 3x-y=-1 what is the value of y
Oksana_A [137]

Answer: The value of y is 2

Step-by-step explanation:

If y=5-3 and 3x-y=-1

Take y=5-3 first

y = 5 - 3

y = 2

Then, take 3x-y=-1, and put y = 2 in the Expression

3x-y=-1

3x - (2) = -1

3x - 2 = -1

3x = -1 + (-2)

3x = -1 -2

3x = -3

To get x, divide both sides by 3

3x/3 = -3/3

x = -1

Thus, the value of y is 2 while x is -1

What are the solutions to the equation?
viva [34]

\qquad\qquad\huge\underline{{\sf Answer}}♪

Let's solve ~

\qquad \sf  \dashrightarrow \:f(x) = g(x)

\qquad \sf  \dashrightarrow \:x + 2 =  -  {x}^{2} +  4

\qquad \sf  \dashrightarrow \: {x}^{2}  + x + 2 - 4 = 0

\qquad \sf  \dashrightarrow \: {x}^{2}  + x - 2 = 0

\qquad \sf  \dashrightarrow \: {x}^{2} + 2x - x - 2 = 0

\qquad \sf  \dashrightarrow \:x(x + 2) - (x + 2) = 0

\qquad \sf  \dashrightarrow \:(x + 2)(x - 1) = 0

Hence, x = -2 or x = 1

1. 1) Simplify the following expression: 5b - 5 - 12b - 7​
Elodia [21]

Answer:

17b - 2

Step-by-step explanation:

5b - 5 - 12b - 7

Say bye to the 12b, and add 12 to it and the 5.

5b + 12 = 17b

17b - 5 - 7

Add 5 to the 5 and the -7.

-7 + 5 = -2.

Now you have 17b - 2. You can’t go farther, so there’s your answer.
