Answer:
10x^4-15x^3+17x^2-13x+17
Step-by-step explanation:
P-2Q
Replace P and Q with the given values,
4x^4-3x^3+x^2-5x+11-(2(-3x^4+6x^3-8x^2+4x-3)
4x^4-3x^3+x^2-5x+11-(-6x^4+12x^3-16x^2+8x-6)
4x^4-3x^3+x^2-5x+11+6x^4-12x^3+16x^2-8x+6
10x^4-15x^3+17x^2-13x+17
So in this case the working would be 35-20= 15
Now we put in the formula. (15/20)*100 which gives us 75. 75% is your percentage change
YX=2, I assume you need to get the 'X' and 'Y' alone. Also just for future reference, you're trying to get variables alone and all the numbers on the other side. Lastly, whatever you do to one side you do to the other. Good luck!
Answer: I would think 1/3
Step-by-step explanation:
If there are 10 large fish and half are red that would mean there is a 5/10 chance of getting a red fish from the large fish.. because there are 15 fish in total you would do 5/15 because there are 15 and 10 of those fish are large and 5 of the large fish are red. And 5/15 to its simplest form is 1/3! If this is right please give brainlist!
