Answer:

y=3 1/3x

This is because x number of minutes times 3 and 1/3 is equal to y or the number of pages. Substitute the value of x to find the answer to the second question:

y= 3 1/3 * 72

Find the explicit formula for the general nth term of the arithmetic sequence described below. Simplify your answer.
Alexandra [31]

\boxed{a_{n}=-3+8(n-1)}

<h2>Explanation:</h2>

The explicit formula for the general nth term of the arithmetic sequence is given by:

a_{n}=a_{1}+d(n-1) \\ \\ \\ Where: \\ \\ a_{n}:nth \ term \\ \\ n:Number \ of \ terms \\ \\ a_{1}:First \ term \\ \\ d:common \ difference

Here we know that:

a_{1}=-3 \\ \\ a_{10}=69

So, our goal is to find the common difference substituting into the formula:

a_{10}=a_{1}+d(10-1) \\ \\ 69=-3+d(9) \\ \\ Solving \ for \ d: \\ \\ 9d=69+3 \\ \\ 9d=72 \\ \\ d=8

Finally, we can write the explicit formula as:

\boxed{a_{n}=-3+8(n-1)}

PLEASE HELP ASAP
andrew-mc [135]

1) Parallel lines have the same slope, so the answer is 1/2

2) Perpendicular lines have slopes that are negative reciprocals, so the answer is -2

3) The equation of the perpendicular is y = -2x - 6, so a point is (0, -6)
