In your own words, explain to me what is absolute value? Make sure to talk about the definition of it, how you find it, and how it's different from just plotting an integer on a number line. You must provide 3 sentences or more.

Answers

Answer:

It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.

This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.

Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.

The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.

Cancel multiplied terms that are in the denominator . Multiply the numbers . Add 4 to both sides of the equation . Simplify.

Answer:

z = -3/2

Step-by-step explanation:

Our goal here is to solve -1/3 (4+z)=-5/6 for z.

Begin by multiplying both sides by 6, to eliminate the fractions:

-2(4 + z) = -5

Isolate (4 + z) by dividing both sides by -2:  4 + z = 5/2

Finally, determine z by subtracting 4 from both sides:  z = 5/2 - 8/2 = -3/2

z = -3/2

Answer:

y = 3x

Step-by-step explanation:

from the table slope or rate of change is

m = 6 - 0 / 2 - 0 = 6/2 = 3

m = 12 - 6 / 4 - 2 = 6/2 = 3

m = 18 - 12 / 6 - 4 = 6/2 = 3

so m = 3

y = mx + c

c is y intercept --> y value when x is 0

y = 0 = c

so line equation is y = 3x + 0

y = 3x

Answer:

B, or 3x.

Step-by-step explanation:

When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.

2 x 3 = 6

4 x 3 = 12

6 x 3 = 18

Therefore, your answer is 3x.

9.7333333333333333334
the answer is 9.73
explanation:
4+5 is 9 so leave that aside for now

since both 2/5 and 2/6 have a different denomination you have to find the common denomination. the common denomination is 30 because it’s the LCM for both 5 and 6.

Since you multiplied the 5 by 6 you now have to multiply your numerator by 6 which will give you 12/30 and do the same with the 2/6 but instead multiply it by 5 which is 10/30 and then add them together 22/30 after you can simplify them to 11/15 by dividing the numeration and denominator by 2

After that you can convert the fraction into a decimal which would be 0.7333 but since you can round it off and make a shorter answer you have 0.73

Lastly,Don’t forget to add your 9 that we had in the begging which is not 9.73 :)
