Answer:
b. because rise over run 1 is positive 3 is negitive
Answer:
1 and 1/2
Step-by-step explanation:
The value of x is 8 when y = 12 if variables x and y have proportional relationship.
According to the given question.
Variables y and x have proportional relationship.
⇒ y ∝ x
Let k be the constant of proportionality.
⇒ y = kx
Also, it is given that
y = 21 when x = 14
Substitute the value of y = 21 and x = 14 in y = kx to find the value of k.
21 = k(14)
⇒ k = 21/14
⇒ k = 3/2
Therefore, the value of x when y = 12
y = kx
⇒ 12 = (3/2)x
⇒ 12 × 2 = 3x
⇒ 24 = 3x
⇒ x = 24/3
⇒ x = 8
Hence, the value of x is 8 when y = 12.

A sequence will be arithmetic if there's a constant difference between terms.
The first sequence is not arithmetic, since the differences between the terms of the sequence are
A sequence is geometric if there's a constant scaling factor being applied to each successive term. To determine if such a constant is there, take the ratio of successive terms.
The first sequence is also not geometric, because the ratios of consecutive terms are
So the first sequence would be assigned (N), which rules out options B and D. Do the same for the next two sequences, which are the only ones you'd need to check.
