What’s the X coordinate of the vertex

Answers

Step-by-step explanation:

f(x) = (x + 3)(x - 5)

In a Quadratic curve, the x-coordinate of the vertex is equidistant to the x-intercepts. (If they exist)

In f(x), our x-intercept are x = -3 and x = 5.

=> (-3 + 5)/2 = 1.

Hence the x-value of the vertex is 1.

Correct answer is x=1

This car dealership pays the salesperson a bonus for selling the car equal to 6.5% of the sale price. How much commission did the salesperson lose when they decided to offer a 10% discount on the price of the car? Show your work.

Answers

Answer: 1%

Step-by-step explanation:

Let x be the sale price.

Commission  = 6.5% of x = 0.065x  (Before discount)

Discount amount = 10% of x = 0.1x

Final sales price = x- 0.1x = 0.9x

Commission after discount = 6.5% of (0.9x)

= 0.065 (0.9x)

= 0.0585x

Loss = ( Commission before discount ) - (Commission after discount )

= 0.065x - 0.0585x

= 0.0065x

Loss percent = [tex]\dfrac{0.0065}{0.65}\times100=1\%[/tex]

Hence, the salesperson lose 1% when they decided to offer a 10% discount on the price of the car.

The sales person lost a commission of 10%.

Let's assume that the price of the car is 1000. The commission the salesperson earns is $65(0.065 x 1000). The price of the car after the 10% discount is $900 (0.9 x 1000). The commission the salesperson earns on the discounted car is $58.5(0.065 x $900). The commission lost = (58.5 / 65) - 1 = 10%

A car is traveling on a small highway and is either going 55 miles per hour or 35 miles per hour, depending on the speed limits, until it reaches its destination 200 miles away. Letting x represent the amount of time in hours that the car is going 55 miles per hour, and y being the time in hours that the car is going 35 miles per hour, an equation describing the relationship is:

55x + 35y = 200

If the car spends 2.5 hours going 35 miles per hour on the trip, how long does it spend going 55 miles per hour?

The probability that Mae will roll an odd number

[tex]P(E) = \frac{3}{6}[/tex]

Step-by-step explanation:

Step(i):-

Given that Mae has a number cube with 6 sides that are numbered 1 through 6.

n(S) = { 1,2,3,4,5,6,} = 6

Let 'E ' be the event of odd numbers

Mae will roll an odd number

n(E) = {1, 3, 5} = 3

Step(ii):-

The probability that Mae will roll an odd number

[tex]P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}[/tex]

[tex]P(E) = \frac{3}{6}[/tex]

Step-by-step explanation:

n = 400

if we choose n as the number, we write are able to write an equation, or number problem.

30% of n = 120

now solve.

first we need to convert 30% to fraction form, which is 30/100.

the reciprocal of 30/100 is 100/30. now multiply 120 by 100/30

(120 x 100) / 30 = 400!

Who will charge more for 5.5 hours, Oscar or Latoya? How much more?


Who?

How much more?

Answers

Answer:

Layota

$47.5

Step-by-step explanation:

Let number of hours = x

Given that:

Oscar's charges :

First hour = $25

Additional hours = $15

Thus :

Total charge : 25 + 15(x - 1)

The piece wise equation given for Layota's charge rate :

First 3 hours = $30

Next 3 hours = $20

Hours greater Than 6 = $10

If total hours ; x = 5.5 hours

Oscar :

$25 + $15(5.5 - 1)

$25 + $15(4.5)

$25 + $67.5

= $92.5

Layota:

First 3 hours :

$30 * 3 = $90

Hours left :

$20 * (5.5 - 3)

$20 * 2.5 = 50

Total = $90 + $50 = $140

Layota charges more : 140 > 92.5

Difference :

$140 - $92.5

= $47.5
