Sin (3x+19)=Cos(5x-25) <br> What is the value of x? <br> A) 6 <br> B) 12 <br> C) 18 <br> D) 24
malfutka [58]

Answer:

B

Step-by-step explanation:

Using the cofunction identity

sin x = cos(90 - x)

Given

sin(3x + 19) = cos(5x - 25), then

3x + 19 = 90 - (5x - 25)

3x + 19 = 90 - 5x + 25

3x + 19 = 115 - 5x ( add 5x to both sides )

8x + 19 = 115 ( subtract 19 from both sides )

8x = 96 ( divide both sides by 8 )

x = 12 → B

Please help! Identify each decimal number as either rational or irrational.
labwork [276]

Answer:

A Rational number is a number that can be written as a ratio in fraction form.

An Irrational number is a number that, when in decimal form, does not terminate or repeat.

Step-by-step explanation:

1.485 can be written as 1 485/1000 - it is rational

0.187345911... continues on and does not repeat - it is irrational

333.051422218... continues on and does not repeat - it is irrational

0.2268715 can be written as 2268715/10000000 - it is rational

1.24 can be written as 1 24/100 - it is rational

Please help<br><br><br>A) x= -4 and 4<br><br>B) x=4 and 6<br><br>C) x=2 and 8<br><br>D) no solution
Neporo4naja [7]

Answer:

No solutions

Step-by-step explanation:

|-2x-10| + 4 = 2

Subtract 4 from each side

|-2x-10| + 4-4 = 2-4

|-2x-10|  = -2

The absolute value is negative so there are no solutions.

Absolute values are always positive, so they cannot be negative.
