Write down the roots of quadratic equation Ax2-bx=0
IgorC [24]

Answer:

x = 0, x = \frac{b}{a}

Step-by-step explanation:

Given

ax² - bx = 0 ← factor out x from each term

x(ax - b) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

ax - b = 0 ⇒ ax = b ⇒ x = \frac{b}{a}

Mr. and Mrs. Preston and their two children are very excited about their upcoming
ki77a [65]

Answer:

They will spend less at the sunny side hotel

Step-by-step explanation:

The attachment completes the question.

From the question, we understand that there are 4 individuals involved.

  • Mr. Preston (1)
  • Mrs. Preston (1)
  • The children (2)

And they will spend one night

First, we need to calculate the expenses in Traveler's hotel.

Rate = \$107.10 (for 3 people)

Additional\ Person = \$21.55 (for 1 person)

Breakfast = \$8.75 * 4 (for 4 people)

Tax = \$16.85

Total Expenses

Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85

Total = \$107.10 + \$21.55 + \$35.00 + \$16.85

Total = \$108.50

For Sunny Side hotel:

Rate = \$152.95 (for 4 people)

Tax = \$21.34

Total Expenses:

Total = \$152.95 + \$21.34

Total = \$174.29

By comparison, they will spend less at the sunny side hotel.
