Integrating gives

To compute the integral, substitute
, so that
. Then

Since
for all
, we can drop the absolute value, so we end up with

Given that
, we have

so that

It is 18-6 out of all the other ones
Use slope formula
y^2-y^1/x^2-x^1
the answer is -4/3
Answer:
a=-8
b=-29
Step-by-step explanation:
Let's assume
first number is a
second number is b
the difference of two numbers,a and b,is 21
so, we get

we can solve for 'a'

the difference of five times a and two times b is 18
so, we get

now, we can plug 'a'

now, we can solve for b




now, we can find 'a'
