Answer:
1, 3, 7, 21
Step by step explanation:
For this case we must find the solution of the following system of equations:

If we multiply the first equation by -2 we have the following equivalent system:

If we add the equations we have:

Thus, the system has infinite solutions.
Answer:
Infinite solutions

Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
Answer:
(8, 8200)
Step-by-step explanation:
It looks like you got it right, the point (8, 8200) is that of a collectors item car, that has not changed much its original price of about £10,000 (at year zero), having a value of £8,200 8 years later.
