The nth term of a sequence is 3n+4 explain why 21 is not a term of this sequence

1 answer:

6 0

In this sequence, n can only be a natural number. So, if you plug in 5 for n, then you get 19. Also, if you plug in 6 for n, you get 24. Since no natural number can be replaced with n to get 21, it isn’t a term in the sequence

Calculate the slope of the line passing through the two colored points below. (1,4) (-1,-1)

leonid [27]

Answer:

Slope = $\frac{5}{2}$

Step-by-step explanation:

We can define the slope as the "change in y values" divided by the "change in x values".

By change in, we mean, 2nd point MINUS the first point values.

The points given is:

(1,4) & (-1,-1)

Change in y value:

-1 - 4 = -5

Change in x value:

-1 -1 = -2

Slope is -5/-2 = 5/2

There is no answer choice. The correct answer is 5/2
