A car dealership sells used cars for $7,000 and new cars for $16,000. If a total of 17 cars were sold for $191,000, how many of
Ipatiy [6.2K]
Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).

-5x^2=0<br><br> PLEASE HELP !! Show work
Fed [463]
This can be translated in two ways.
 (-5x)^2 = 0
or 
-5(x^2) = 0
Either way, the only way that this could be equal to 0 is if x = 0. 
Therefore the solution is x = 0.

A second-order linear differential equation for y(t) is said to be homogeneous if... every term involve either y or its derivati
swat32

Answer: Hello!

A second order differential equation has the next shape:

y''(t) + p(t)y'(t) + q(t)y(t) = g(t)

where p(t), q(t) and g(t) are functions of t, that can be constant numbers for example.

And is called homogeneus when g(t) = 0, so you have:

y''(t) + p(t)y'(t) + q(t)y(t) = 0

Then a second order differential equation is homogeneus ef every term involve either y or the derivatives of y.
