Hello from MrBillDoesMath!
Answer:
For y = 4x, the domain of the function is all real numbers. This can be indicated as ( -infinity, infinity),
...later part of question:...
..."because an exponent can be any real"
exponent? !!!
Did you mean y = 4^x ? In this case the domain of y is all real numbers ann the range is (0, infinity), where the value 0 is not included in the range.
Thank you,
MrB
Answer:
The answer would be 1.33 x 
Step-by-step
1.28 x = 12800
5 x 
= 500
12800 + 500 = 13300
13300 = 1.33 x in scientific notation
Hope this helps:)
Sorry, I got the wrong answer earlier but I fixed it:)
The two figures are congruent because the side lengths are the same, therefore making the angle measures the same.
Hi there! So, the simple interest is 7.5% annually. Let’s multiply by initial amount by the interest rate. 5,000 * 7.5% is 375. You earn $375 in interest annually. The difference of 6,500 and 5,000 is 1,500. Let’s divide by 375 to see how many times it goes into 1,500. 1,500/375 is 4. It will take 4 years for the balance of the account to be $6,500.
they are supplementary angles
