If you are talking about 2x^2 + x + 6 then the intervals would be decreasing based on where it is based on the vertex,
-b/2a = -1/2, plug -1/2 in 1/2 -1/2 + 6 = 6, vertex = (-1/2, 6) so the equation is decreasing (infinity) > x > -1/2

A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends
Ostrovityanka [42]

Answer:

  • $7.39

Step-by-step explanation:

Let the initial price be x

<u>Then the reduced price is </u>

  • x - 1.75

<u>If 5 mugs cost $28.20, we have equation:</u>

  • (x - 1.75)*5 = 28.20
  • x - 1.75 = 28.20/5
  • x - 1.75 = 5.64
  • x = 1.75 + 5.64
  • x = 7.39

Initial price for 1 mug was $7.39

What is the best estimate for the length of a bike
castortr0y [4]
<span>The average length of a bike (including the length of both wheels) is about 68 inches.For finding the true answer we must follow the following convertion rule: 1 inch is equivalent to 0.02 yard, so 68 inches equal to 1.88 yards. Consequently, the value nearest 1.88 yards is 1.5 yards, so the answer is the choice A: 1.5 yards. </span>

an experiment consists of flipping a fair coin 4 times. What is the probability of obtaining at least one head?
Dvinal [7]
\mathbb P(X\ge1)=1-\mathbb P(X=0)

The probability of getting 0 heads in 4 tosses (or equivalently, 4 tails) is \dfrac1{2^4}=\dfrac1{16}.

So the desired probability is

1-\dfrac1{16}=\dfrac{15}{16}
