This is a very good question to know about. People who make tests really like it.

The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.

The difference in speeds  is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???

t = d/r
t = 260/8
t = 32.5 hours.

Thats 32 1/2 hours.

How do I find the percentile of someone with a certain number of things from a dot plot data set?
dalvyx [7]

Answer:

percentile rank of x =

number of values before x                           100

---------------------------------------------------  x    ----------

number of total values on the dot plot         1

Step-by-step explanation:

you divide the number of values before x over the number of total values on the dot plot, and divide the quotient by 100 to get your percentile.

The function g is defined by the following rule.<br> §(¢=3x+5<br> Complete the function table.
Oxana [17]

The table with the numeric values of g(x) is given by:

  • x = -5, g(x) = -10.
  • x = -1, g(x) = 2.
  • x = 1, g(x) = 8.
  • x = 3, g(x) = 14.
  • x = 5, g(x) = 20.

<h3>What is the complete problem?</h3>

Researching it on a search engine, it is found that we have to calculate the numeric values of g(x) = 3x + 5 for x = -5, -1, 1, 3 and 5.

<h3>How to find the numeric value of a function?</h3>

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is given by:

g(x) = 3x + 5.

Hence the numeric values are:

  • g(-5) = 3(-5) + 5 = -10.
  • g(-1) = 3(-1) + 5 = 2.
  • g(1) = 3(1) + 5 = 8.
  • g(3) = 3(3) + 5 = 14.
  • g(5) = 3(5) + 5 = 20.

The distance between the parallel lines x – 2y = 3 and 2x – 4y = 12 is
Svetradugi [14.3K]

Given :

Parallel lines are

x – 2y = 3 and 2x – 4y = 12

Step-by-step explanation:

Lets write the given lines in slope intercept form y=mx+b

x -2y = 3  \\-2y=-x+3\\Divide \; both \; sides \; by -2\\y=\frac{x}{2} -\frac{3}{2}

From the above equation , y intercept of first line is \frac{-3}{2}

Solve the second equation for y and find out y intercept

2x-4y=12\\-4y=-2x+12\\Divide \; by \; -4\\y=\frac{1}{2} x-3

y intercept of second line is -3

To find the distance between parallel lines, we subtract the y intercepts

\frac{-3}{2} -(-3)=\frac{-3}{2} +\frac{6}{2} =\frac{3}{2} =1.5

Answer:

The distance between the parallel lines = 1.5

Please anwer what is X and give the explantion,how did you get the answer.ASAP
grigory [225]

We can solve x through simple algebra.

x + 5 = 2

x = 2 - 5

x = -3

x - 10 = 22

x = 22 + 10

x = 12

x - 27 = 8 + 10

x - 27 = 18

x = 18 + 27

x = 45

-11 + x + (-48) = 25

-11 + (-48) + x = 25

-59 + x = 25

x = 25 + 59

x = 84

x - (-16) = 12 + 13

x + 16 = 25

x = 25 - 16

x = 9

Tip: As you can see, the number sign changes as they shift from left to right (ex. -59 to +59).
