How do you use a number line from least to greatest

Mathematics
1 answer:
Arlecino [84]2 years ago
6 0

Step-by-step explanation:

left to right.

the smallest numbers are on the left, the largest in the right.

all the numbers in the line are sorted.

so, going from left to right the numbers get continuously larger (no exception), and when going from right to left, they get continuously smaller.

remember that the negative numbers are smaller than the positive numbers. so, the negative numbers (if there are any in your case) are on the left side.

and negative numbers get smaller by "seemingly increasing" : -1 is larger than -2 and so on.

so, the range of the negative numbers starts on the left side with the "largest" negative number (but when you think about it, it IS the smallest number) and their absolute value gets smaller until they reach 0, and then the positive numbers start from small to large.

this also asked to fractions and mixed fraction numbers :

e.g. -2 1/2 is smaller than -2 and larger than -3.

because it is -2 + -1/2 = -2 - 1/2 = -2 1/2.

in that sense it is the same principle as with positive numbers :

2 1/2 = 2 + 1/2

-2 1/2 = -2 - 1/2

2. If AB = 4x + 9. BC = 5x + 2, and AC = 56, then find the value for . AB, BC.<br> A<br> B
inysia [295]

Answer:

AB=29; BC=27

Step-by-step explanation:

So they told us AB=4x+9 and that BC=5x+2, and AC=56 , now to help with the question you can draw this information on a number line. Now on a number you can see that basically AC=AB+BC.

So you would write it as such,,

4x+9+5x+2=56

Combine like terms

9x+11=56

Now you have to isolate the x by itself but first get rid of the 11.

9x+11-11=56-11

You would get

9x=45

Here you can divide 9 by both sides to isolate x.

9x/9=45/9

{x=5}

Now to find the value for both substitue x in the equations for both

1. AB=4x+9 where x is 5

4(5)+9 =AB

20+9 =AB

29=AB

You would do the same with BC

2. BC= 5x+2 where x is 5

5(5)+2= BC

25+2= BC

27=BC

If you want to check your answers you can just substitute x for 5 in the first equation we did where AC=AB+BC

Which of the following is equivalent to the complex number i^17
Anton [14]

Answer:

Step-by-step explanation:

It’s a repeating pattern.

i² = -1

i³ =(i²)i = (-1)i = -i

i⁴ = i³i = -i² = 1

i⁵ = (i⁴)i = (1)i = i

i⁶ = i⁵i = i² = -1

...

i¹⁷ = i
