Answer:

$392.  No they don't have enough money to pay for the trip.

They need $255 more dollars, which would take 14 weeks and 2 days.

Step-by-step explanation:

18 x 4 = 72

320 + 72 = 392

647 - 392 = 255

255/18 = 14.2

In 15 words or fewer, describe what happens to the coordinates when
andriy [413]

Answer:  The graph becomes narrower

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k   where

  • |a| represents the vertical stretch if |a| > 1, vertical shrink if |a| < 1
  • (h. k) represents the vertex

A vertical stretch means the curve gets narrower.

A vertical shrink/compression means the curve gets wider.

I need the answer please. Because I think i got mine wrong
Gekata [30.6K]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

• a^{-m} ⇔ \frac{1}{a^{m} }

• a^{0} = 1

• a^{m} × a^{n} ⇔ a^{(m+n)}

Given

(a)

8^{-2} = \frac{1}{8^{2} }

(b)

\frac{1}{3^{-3} } = 3³

(c)

6^{-12} × 6^{8} × 6^{0}

= 6^{(-12+8)} × 1

= 6^{-4}

= \frac{1}{6^{4} }
