1st term a₁ = - 3.7; common difference d = - 1.3
the nth term a(n) = a₁ +(n-1)d or a(n) = 3.7 + (n-1)(-1.3)
a(n) = - 3.7 - 1.3n + 1.3 ====> -2.4 - 1.3.n Or as per your answer:
a(n) = -1.3.n - 2.4
Answer:
C.
Step-by-step explanation:
Check the picture below.
so the volume of the smaller cube will just be (1/3)³.
how many of those cubes will take to fill up the larger cube?
namely
how many times does (1/3)³ go into 44?
The difference between the two given equations is that 1 is subtracted from 2x in the first equation while this is missing from the second. If we are going to add 1 to both sides of the first equation, we get the answer of,
y + 1 = 2x - 1 + 1
y + 1 = 2x
As we can see, the equation above is similar to y = 2x except that +1 is added to the y value. Thus, your graph is translated 1 unit up.
