Y-ypt = m(x-xpt)
y-2 = -3 (x-2)
y = -3x +6 +2
y = -3x +8
The answer is D because linear functions represent y=mx+b and D is the one that represents it.
Answer:
5.78×10¹⁵
Step-by-step explanation:
The playlist has 12 songs, and he wants the same number of songs for each genre, so he must pick 4 songs per genre.
The number of ways he can choose 4 country songs (ignoring the order) is ₂₂C₄ = 7315.
The number of ways he can choose 4 reggae songs (ignoring the order) is ₁₁C₄ = 330.
The number of ways he can choose 4 pop songs (ignoring the order) is ₅C₄ = 5.
The total number of combinations is 7315 × 330 × 5 = 1.21×10⁷.
Once he has his 12 songs selected, the number of ways he can arrange them is ₁₂P₁₂ = 12! = 4.79×10⁸.
So the total number of possible playlists is:
(1.21×10⁷) × (4.79×10⁸) = 5.78×10¹⁵
Answer:
The equation is 39=3r-6
Step-by-step explanation:
Let x = # of years from the start of the Great Depression to the first Presidential election of Nixon
Let r = Raul's age
The question gives us what x equals so...
x=39
Now we just turn the sentence into an equation.
"The number of years from the start of the Great Depression to the first Presidential election of Nixon [(x)] is six years less than three times Raul's age [(3r-6)]"
Remove the icky words...
x=3r-6
replace x with what it equals (39)
39=3r-6
Now you can go on to olve it
Overal Raul is only 15 :)
Answer:
35.775
Step-by-step explanation:
So, 53 is the amount of ccs that makes a 40% solution.
How can we find the ccs of 27% solution?
Well, we should first find teh amount of ccs per 1%.
To do this, divide 53 by 40:
53/40
=
1.325
Now multiply this by 27 to get the amount of ccs for 27%:
27*1.325
=
35.775
Hope this helps! :)
