The answer is C, 6 x 4 = 24!
So the formula for an arithmetic sequence (where you're adding or subtracting by the same number each time) is = + d(n - 1)
In this equation:
is the nth term
is the first term
d is the common difference (the number you're adding or subtracting each time)
n is the number of the term (e.g. 1st term, 2nd term, 3rd term etc)
So we're given that = -27, and we can find that d = 15 (because we add 15 each term). We just plug these values into the equation to get...
= -27 + 15 (n - 1)
It looks like that's your answer, D. But if you needed to solve it out further, you could:
We can use the distributive property...
= -27 + 15n - 15
Then combine like terms...
= 15n - 42
Hope that helps! Feel free to message me if you need clarification

Answer:
T1he values for x and y of the equations is y = 11, and x = -19/5.
Step-by-step explanation:
To solve this question, we need to rearrange the expression:
5x+4y=25 - (5x+2y=3)
Look, if we subtract one equation to the other, then:
5x+4y=25 [1]
-(5x+2y=3) [2]
Which is the same as:
5x+4y=25
-5x-2y=-3
Subtract them:
5x+4y=25
-5x-2y=-3
---------------
2y =22
y = 22/2 = 11
Then, y = 11.
To find x, we can substitute<em> y</em> in either equation [1] or [2].
Let us use [1]
5x+4y=25
5x+4(11)=25
5x+44=25
5x=25-44
5x=-19
x = -19/5
Then, the values for x and y of the equations is y = 11, and x = -19/5.
I think the correct answer from the choices listed above is the second option. The value of 0.94 in the function given above represents the decrease of the value of the car per year. Hope this answers the question. Have a nice day.
