Answer:
1. <u>+12x</u> and <u>15</u>
2. <u>14x</u>
3. <u>2</u>
Step-by-step explanation:
Step 1: Distribute -3
To distribute -3, you would multiply both -4x and -5 by -3, changing them to 12x and 15
Step 2: Combine 12x and 2x
Then you would combine like terms, meaning that you would add 12x and 2x, creating 14x.
Step 3: Combine 15 and -13
You would finish combining like terms by adding 15 to -13, creating 2
Answer: -44
Step-by-step explanation:
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
