Answer:

a_n = 14-1.5n

Step-by-step explanation:

The explicit rule for the arithmetic sequence is given by:

a_n =a_1+(n-1)d          ....[1]

where,

a_1 is the first term

d is the common difference and n is the number of terms.

Given sequence:

12.5, 11, 9.5, 8, 6.5, 5 ...

This is an arithmetic sequence.

here, a_1=12.5  and d =- 1.5

Substitute these in [1] we have;

a_n = 12.5+(n-1)(-1.5)

⇒a_n = 12.5-1.5n+1.5

⇒a_n = 14-1.5n

Therefore, the explicit rule for the given sequence is, a_n = 14-1.5n

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
Zigmanuir [339]
-3x-6y=17

-6y=3x+17

y=-x/2-17/6 so the slope of the line is -1/2

For another line to be perpendicular to this one the product of their slopes must equal -1

(-1/2)m=-1, m=2  so the perpendicular line will have a slope of 2...

y=2x+b, using point (6,3) we can solve for b...

3=2(6)+b

3=12+b

b=-9 so

y=2x-9
