What is the slope of y = -1

Mathematics
1 answer:
alexdok [17]3 years ago
7 0

Slope is rise/run.

y=-1 is a horizontal line where the y value is always one no matter what x is.

Therefore the rise is 0 and run is infinite

so 0/infinity=0 because 0/anything=0.

One thing I want to note is if you have a vertical line, where rise is infinite, and run is 0 infinite/0=undefined because you can't divide by 0 :-)

Answer:

There can be a number of correct answers. One of them is the ship has traveled 25 miles in 1 hour.

Step-by-step explanation:

The distance from destination f after x hours for the ship is given by f(x)=120-25x

At the beginning, x=0, f(x)=f(0)=120

After 1 hour, f(x)=f(1)=120-25=95

So in 1 hour, the ship has traveled 120-95=25 miles.

Alenkasestr [34]

Answer:

1)  \frac{5}{-14}=0.3571428571 2) Terminating

Step-by-step explanation:

1st. To answer this question let's divide with long division algorithm  5 and -14.

  <u> 0.3571428571</u>

-14)50

    42

     ---

     80

     -70

      --

    100

      98

      ---

     20

     14

    ----

      60

      -56

       ---

      40

       28

      --

     120

    -112

     ----

       80

       70

       --

      100

       -98

      --  

       2

5 (dividend) : -14 (divisor) \frac{5}{-14}

Long division (check below)

With the same two numbers -14 and 5 we can write in a Long Division

 

5) -14

<u>   - 2.8</u>

5) -14

    10

   40

So \frac{-14}{5}=-2.8

2nd. Both are terminating ones for they have finite quantities of numbers. -2.8 and 0.3571428571, as we can see that these are rational numbers for they can be written as a/b, and b≠ 0.

\frac{5}{-14} form.

\frac{-14}{5} form.

In an all boys school, the heights of the student body are normally distributed with a mean of 70 inches and a standard deviatio
almond37 [142]

Answer:

0.010

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = 63 inches

μ is the population mean = 70 inches

σ is the population standard deviation = 3 inches

For x shorter than 63 inches = x < 63

Z score = x - μ/σ

= 63 - 70/3

= -2.33333

Probability value from Z-Table:

P(x<63) = 0.0098153

Approximately to the nearest thousandth = 0.010

Therefore, the probability that a randomly selected student will be shorter than 63 inches tall, to the nearest thousandth is 0.010.
