Answer:

The parabola will reflect over the x axis.

Step-by-step explanation:

By setting the "a" value to a negative number, you will be inverting the f(x) values, in other words making a parabola open downwards, or a direct reflection over the x axis of the parent formula.

Take f(x)=1x^{2}+0 for example.

if we plug in 1 for x f(x) will equal 1

however if we make the a value negative

f(x)= -1x^{2}+0

and set x equal to 1,

you should see that f(x) is now -1

Sherrod and Kamar are planning to drive at most 900 miles road trip. Sherrod drives at 60 miles per hour, and Kamar at 50 miles
Allushta [10]

The inequality gives the total expected journey from the road trip, such that the time during which Sherrod and Kamar drives is known.

  • a. The inequality that represents the miles that Sherrod and Kamar drives is; <u>x + y ≤ 900</u>
  • b. Two possible combination of <em>x</em> and <em>y</em> are; <u>(600, 300) and (300, 600)</u>

Reasons:

a. The distance distance Sherrod and Kamar plan to drive ≤ 900 miles

Sherrod's speed = 60 mph

Kamar's speed = 50 mph

The distance Sherrod drives = x

The distance Kamar drives = y

a. The miles driven by Sherrod and Kamar is given by the inequality;

  • <u>x + y ≤ 900</u>

b. Two possible combinations are;

First possible combination;

Sherrod drives for 10 hours, which gives;

Distance Sherrod drives = 60 mph × 10 hour = 600 miles

Kamar drives for 900 miles - 600 miles = 300 miles

Which gives;

Sherrod drives for 600 miles and Kamar drives for 300 miles

  • <u>First combination; (600, 300)</u>

Second possible combination;

The second possible combination is Sherrod drives for 300 miles and Kamar drives for 600 miles

  • <u>Second combination; (300, 600)</u>

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day. According to a
Degger [83]

Answer:

The equation that models this scenario b(x)=(3+0.5x)(38-4x)

Step-by-step explanation:

First we convert 50 cent into dollar,

1 cent =\frac{1}{100} dollar

1 cent = 0.01 dollar

50 cent = 0.5 dollar

According to question,

x is the number of 50¢=$0.5 price increases.

b(x) is the revenue generated

He currently charges $3 per book.

i.e. price of book = 3+0.5x

Quantity or average = 38 per day

According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.

i.e. quantity became 38-4x

Revenue = Price × Quantity

The required equation is given by,

b(x)=(3+0.5x)(38-4x)
