The sum of twice a number and another number is 24. The difference of twice the first number and the other number is 12. Which s

dem82 [27]

Answer:

The system that models the situation is:

$\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.$

The solution is:

(9, 6)

Step-by-step explanation:

We must write the equations as indicated in the problem.

The sum of twice a number and another number is 24

a number: x

other number: y

Then

$2x + y = 24$

The difference of twice the first number and the other number is 12

first number: x

other number: y

Then:

$2x - y = 12$

The system that models the situation is:

$\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.$

To solve the system we add both equations to find the value of x

$2x + y = 24\\\\2x - y = 12$

---------------------

$4x +0 = 36\\\\x=\frac{36}{4}\\\\x=9$

$2(9) +y = 24\\\\y=24-18\\\\y=6$

The solution is:

(9, 6)

Solve the equation on the interval [0,2π). cos^4x=cos^4xcscx

Luba_88 [7]

$\bf cos^4(x)=cos^4(x)csc(x)\\\\
-----------------------------\\\\
cos^4(x)=cos^4(x)\cfrac{1}{sin(x)}\implies cos^4(x)=\cfrac{cos^4(x)}{sin(x)}
\\\\\\
cos^4(x)sin(x)=cos^4(x)\implies cos^4(x)sin(x)-cos^4(x)=0
\\\\\\
cos^4(x)[sin(x)-1]=0\to 
\begin{cases}
cos^4(x)=0\to x=cos^{-1}(0)\\
----------\\
sin(x)-1=0\\
sin(x)=1\to x=sin^{-1}(1)
\end{cases}$

$\bf \measuredangle x = cos^{-1}(0)\implies \measuredangle x = 
\begin{cases}
\frac{\pi }{2}\\\\
\frac{3\pi }{2}
\end{cases}
\\\\\\
\measuredangle x=sin^{-1}(1)\implies \measuredangle x=\frac{\pi }{2}$
