Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.
Svetradugi [14.3K]

Answer: $20

Step-by-step explanation:

Let 'x' be the cost of a ticket at Haynes

Let 'y' be the cost of a ticket at Valley

Since the total cost from both schools are the same, we can write it as:

60x=80y

Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:

y=x-5

Now we have two equations, we can use to substitute into the other expression:

60x=80y

60x=80(x-5) we substitute y in this equation with the other equation

60x=80x-400

-20x =-400

x = 20

Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.

What is the completely factored form of x4 8x2 – 9?
Alinara [238K]

For this case we have the following polynomial:

x ^ 4 + 8x ^ 2 - 9

We make the following change of variables:

u = x ^ 2

Rewriting we have

u ^ 2 + 8u - 9

Factoring the second order polynomial we have:

(u + 9) (u-1)

Then, returning the change we have:

(x ^ 2 + 9) (x ^ 2-1)

Finally, we factor the expression in the parentheses of the second term:

(x ^ 2 + 9) (x + 1) (x-1)

Answer:

the completely factored form is:

(x ^ 2 + 9) (x + 1) (x-1)
