Write the equation of a line that is perpendicular to y=-2/7x + 9 and that passes through the point (-4,6) [FP]​
siniylev [52]

Answer:

$y=(7/2)x+20$

Step-by-step explanation:

SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.

Therefore by the point slope formula the line that we are looking for is

$y-6=(7/2)(x+4)$

$y=(7/2)x + 20$

Find the 137th odd number.
KIM [24]

The first odd number is 1. The next is 2 more than the previous one.

It's an arithmetic sequence.

The general term of an arithmetic sequence:

a_n=a_1+(n-1)d

a_n - n-th term

a_1 - first term

d - common difference.

We have

a_1=1,\ d=2,\ n=137

Substitute:

a_{137}=1+(137-1)(2)=1+(136)(2)=1+272=273

<h3>Answer: 137th odd number is equal 273.</h3>
