Answer:
absolute value its written as:
| expression | > x
*> written can also be < , ≥ , or ≤
| | (two vertical lines on both sides of something) indicate absolute value
(absolute value considers the space between a number and 0;
| x | = 3
then x could be = 3 or = -3
you can also think of anything inside | | to be written as positive;
| 3 | = 3
| -3 | = 3)
you could also right, from this example: | x | > 3
our value of x could either be greater than 3, or, our x-value is negative (and only the absolute value is greater than 3, meaning that negative -x, is greater than three)
we separate these possibilities into two expressions:
x > 3 - x > 3
· -1 · -1 {inequalities flip direction when multiply by negative}
x < -3
so, x > 3 and x < -3 can be combined:
x > 3 <em>or </em> x < 3

You would divide £52.65 by 27 to find out what 1 packet costs, thus leads us to £1.95. Then you would do £1.95 x 35 as there are 35 packets to get the answer £68.25
To find this, you just need to plug it in and use some algebra to figure it out.
Initial: 2700 = 2200(1 + r)5
multiply 2200 and 5: 2700 = 11000(1 + r)
Divide both sides by 11000: .24 = 1 + r
subtract both sides by 1: -.754 = r
The problem is, a negative interest rate makes no sense if there was actually an increase of 500. We can try distributing the 11000 instead
Where we left off: 2700 = 11000(1 + r)
Distribute the 11000: 2700 = 11000 + 11000r
Subtract 11000 from both sides: -8300 = 11000r
Divide both sides by 11000: -.754 = r
As you can see, both methods reached the same impossible answer. I'm assuming that you didn't type out the equation right. Are you sure it wasn't
2700 = 2200(1 - r)5
? If you subtract the r to make it negative, it might make more sense. But that still leaves us with a .754 rate of interest, which seems too high. Double check where you're typing from
Answer:
yes a function
Step-by-step explanation:
it goes thru every x option
77 + 83 = 160, multiply that by 14 days, gives you 2,240
