Easy buddy...
[tex]5x - 15 = 3x + 7[/tex]
Subtract the sides of the equation plus 15
[tex]5x = 3x + 7 + 15[/tex]
[tex]5x = 3x + 22[/tex]
Subtract the sides of the equation minus 3x
[tex]5x - 3x = 22[/tex]
[tex]2x = 22[/tex]
Divided the sides of the equation by 2
[tex]x = \frac{22}{2} \\ [/tex]
[tex]x = 11[/tex]

Assume you have 3,000 songs downloaded to your mobile phone. Of these songs, 50 songs are by your favorite artist. If you play the songs on random shuffle, how many songs would you have to listen in a row before you heard a song by your favorite artist?
Answer:
2950
Step-by-step explanation:
i just subtracted 3,000 with 50
There are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.
What is random shuffle of songs?
Shuffle play is a type of music playback in which all tracks are selected at once and songs are played in a random order. Media player software, digital audio players, and CD players all frequently have it.
Given: You have 3,000 songs downloaded to your mobile phone.
Of these songs, 50 songs are by your favorite artist.
So, the number of songs would you have to listen in a row before you heard a song by your favorite artist are,
3000 - 50 = 2950.
Therefore, there are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.

Tammy purchased a prepaid phone card for $15. Long distance calls cost 18 cents a minute using this card. Tammy used her card only once to make a long
distance call. If the remaining credit on her card is $6.72, how many minutes did her call last?
Answer:
46 minutes
Step-by-step explanation:
Sorry about not answering your question sooner, but here is your answer:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:
15 - 6.72 = 8.28
Then, we divide this number by 0.18:
8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes

Write y=2x^2+24x+47 in vertex form. Also please explain/write the steps thanks.
Answer:
y=(2x^2+24x)+25
y=2x(x^2+12x)+25
y=2x(x^2+12x+36)+25-2x(36)
Y=2x(x+6)^2+25-72
Y=2x(X+6)^2-47
Step-by-step explanation:
sorry it was late
Answer: y=2(x+6)²-5
Step-by-step explanation: First you find the coefficient of x^2, which is 2, then take out 2 as a factor, 24/2 which will equal to 12. After that do 47 divided by 2 if you calculate that it will equal to 23.5. y=2(x²-12+23.5) y =2(x²-12x+23.5)
Next Step: Figure out the coefficient of x. To make it easier,look what is in front of x as you can see it is 12. Then you divide 12/2 which is 6. Then square 6, which is 36. Then you add and subtract 36. To write the first three terms as a square, you do ( x+6)^2. Then do -36 + 23.5 if you calculate that it will get you wil get -12.5 . Now that you have calculated that distribute 2, then do 2 times -12.5 which is -12.5. This is how it shoud look like y=2(x+6)² -12.5.

Step-by-step explanation:
the range of a problem is basically the difference between the smallest and the largest y value. the largest y value here is 6 and the smallest is 3, so 6-3 = 3 -> 3 is your range! now for domain: the domain of a problem is the difference between the smallest and largest x value. the largest x value is 2 and the smallest is -2, so 2 - -2 = 4 -> the domain is 4! hope this helped!

Choose a justification for each step in the derivation of the sine difference identity.
Answer:
Step-by-step explanation:
The missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even and sine function is odd respectively.
Given:
The given expression is [tex]\sin (x-y)[/tex].
To find:
The justification for each step.
Explanation:
Cofunction identities:
[tex]\sin\left(\dfrac{\pi}{2}-x\right)=\cos x[/tex]
[tex]\cos\left(\dfrac{\pi}{2}-x\right)=\sin x[/tex]
Cosine difference identity:
[tex]\cos(x-y)=\cos x\cos y+\sin x\sin y[/tex]
Cosine function is even, so [tex]\cos(-x)=\cos x[/tex].
Sine function is odd, so [tex]\sin(-x)=-\sin x[/tex].
We have,
[tex]\sin (x-y)[/tex]
[tex]=\cos\left|\dfrac{\pi}{2}-(x-y)\right|[/tex] Step 1: Cofunction identity
[tex]=\cos\left|\dfrac{\pi}{2}-x+y\right|[/tex] Step 2: Distributive property
[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)+y\right|[/tex] Step 3: Associative property
[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)-(-y)\right|[/tex] Step 4: Factoring out
[tex]=\cos\left(\dfrac{\pi}{2}-x\right)\cos(-y)+\sin\left(\dfrac{\pi}{2}-x\right)\sin(-y)[/tex] Step 5: Cosine difference identity
[tex]=\sin(x)\cos(-y)+\cos(x)\sin(-y)[/tex] Step 6: Cofunction identity
[tex]=\sin(x)\cos(y)-\cos(x)\sin(y)[/tex] Step 7: Cosine function is even, sine function is odd
Therefore, the missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even, sine function is odd respectively.
