Answer: yes.
Step-by-step explanation:
If you are meaning Nine times Nine the answer is 81.
To be written in standard form, the exponents need to be in order from largest to smallest.
The answer is: a. −3x^5 + 4x^3 + 10x^2
12x+y=10 -----> 12x + y = 10
-3=3x+3y ------> -12x - 12y = 12 (multiplied by -4)
-11y = 22
y= -2
12x - 2 = 10
x = 1
