Well i know its definitly not B if that helps
The answer is D. Initial value : 20, rate of change -10. I hope this helped!
Answer:
an imaginary integer
Step-by-step explanation:
80 is an integer, so is also a rational, whole, and natural number. The i multiplier makes it imaginary, so also complex.
There are many ways to describe the number. Perhaps "imaginary integer" is a suitable description.
Step-by-step explanation:
step 1. why are you in a hurry?
step 2. a binomial that is a common factor of 121 - 25x^2 and 25x^2 + 55x + 121.
step 3. the factors. of 121 - 25x^2 are (11 - 5x)(11 + 5x).
step 4. the factors of 25x^2 + 55x + 121 are (5x + 11)(5x + 11).
step 5. the common factor is 5x + 11.
5x=5
If it was any other solution, the equations would'nt make sense
