<u>To find the distance between the two points, we must use the distance formula</u>

 ⇒ <em>Distance Formula ⇒ </em>\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

  • (x_1,y_1): one_.point_.on_. the_.line
  • (x_2,y_2):another_.point_.on_.the_.line

<u>Now let's consider the information:</u>

  • <u />(x_1,y_1): (-10,-9)
  • (x_2,y_2):(-1,-5)

<u>Let's solve:</u>    

    Distance_.between_.EG = \sqrt{(-5--9)^2+(-1--10)^2} =\sqrt{4^2+9^2}\\Distance_.between_.EG=\sqrt{16+81}  \\Distance_.between_.EG =\sqrt{97} \\Distance_.between_.EG=9.85

<u>Thus by rounding to the nearest tenth</u>

  ⇒ <u>Answer: 9.9</u>

Hope that helps!

A train leaves Westchester at 6:30. What time should it arrive at Middlewich
Sholpan [36]

Answer:

a). 6:51

b). 6:30 am

c). 34 minutes

Step-by-step explanation:

a). Train leaves Westchester at 6:30.

   From the arrival - departure table in column (2),

   Arrival time of the train at middlewich = 6:51

b). Kate has to reach Southam before 9:00 am

   Therefore, time of the latest train that she can catch to get to work on time is 6:30 am

    By this train she can reach at 07:19 at Southam.

c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00

                                                                                        = 00:34

                                                                                        ≈ 34 minutes

A 65-inch HD LCD television is discounted 25% from the original price. If the discounted price is $1799.99, what was the origina
Andreas93 [3]

Answer:

$2399.99

Step-by-step explanation:

the price of the tv is discounted by 25%

that is the same as saying the tv is 75% of its original price

so we take $1799.99/75 to see what one percent of the price is

$1799.99/75=23.9998

then we take 23.9998*100 to see what the original price was

23.9998*100=2399.986667 and then we round to the nearest hundredth

so 2399.99

Let f(x) = 3x2 + x − 3 and g(x) = x2 − 5x + 1. Find f(x) − g(x).
Lubov Fominskaja [6]
       f(x)  -  g(x)
=>  (3x²  +  x  - 3)  -  (x² - 5x + 1)
=>  3x² + x - 3 - x² + 5x - 1
=>  3x² - x² + x + 5x - 3 - 1
=>  2x² + 6x - 4
