Please help!!!Which of the following lines is parallel to x=8?

3y=16

X=7

X=y

Y=8


Select the equation of the line that passes through the points (5,7) and is perpendicular to the line x=4.

Y=4

X=5

Y=7

X=7

Answers

Answer 1
Answer: The answer to question #1 is x = 7

For a line to be parallel to x = 8, it has to start with x = some number. Such a line would have an undefined slope.

Now, x = y is a line that goes through the origin. It has a slope of 1.

The answer to question #2 is y = 7

If a line is perpendicular to x = some number, then it has to be y = some number.

And this perpendicular line has to go through the point (4,7). So what is the y-value of this point, since the equation starts with y? The y-value is 7. So the equation has to be y = 7

Answers

1. The mode is C. 18
2. The median is B. 16
3. The mean is D. 14.25
4. The median is 2.3
5. The mean is 18
1) the mode is the number that repeats the most in a given set of numbers, so the answer would be c, 18
2) the median is b, 16 (if you put the numbers in chronological order, there are two middle numbers, to get the median you have to average those two numbers)
3) the mean is d, 14.25 (add all the numbers up and divide by the amount of numbers that you have [if you have 5 numbers, you divide by 5])
4) the median is 2.3
5) the mean is 18

Joys mom begins to walking at 4:12 p.m. she stops at 4:43 p.m. how many minutes does she walk?

Answers

By walking from 4:12 pm to 4:43 pm, Joy's mom was able to walk for 31 minutes

Joy's mom walked from 4:12 pm to 4:43 pm.

To find out the number of minutes she walked, subtract the time she started walking from the time she stopped walking:

= Time stopped - Time started

= 4 :43 - 4:12

= 43 - 12 ⇒ isolate the minutes to make the subtraction easier

= 31 minutes

In conclusion, Joy's mom walked for 31 minutes.

Subtract the two numbers from largest to smallest:
4.43-4.12    (or because the hour is the same, you can leave the 4 out)
43-12=31
31 minutes

Someone drove 20 miles in 24 minutes at this rate how many miles did they drive in 6 minutes

Answers

distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t 
r = 20mi/24min
= 0.833333 mi/min.

d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles

What is 2/5 of 16 miles?

Answers

Here is an easy way to figure this out, do 16/5 (16 divided by 5) then what ever that equals, times it by 2 since it's 2/5 not 1/5. Once you do all of this, it should equal 6.4
