X-X^2/ (x-3)^2 try that I’m not 100% sure tho
Answer:
-19 y^2 + 18 x y + 13 x^2
Step-by-step explanation:
Simplify the following:
16 x^2 + 15 x y - 19 y^2 - (3 x^2 - 3 x y)
Factor 3 x out of 3 x^2 - 3 x y:
16 x^2 + 15 x y - 19 y^2 - 3 x (x - y)
-3 x (x - y) = 3 x y - 3 x^2:
16 x^2 + 15 x y - 19 y^2 + 3 x y - 3 x^2
Grouping like terms, 16 x^2 + 15 x y - 19 y^2 - 3 x^2 + 3 x y = -19 y^2 + (15 x y + 3 x y) + (16 x^2 - 3 x^2):
-19 y^2 + (15 x y + 3 x y) + (16 x^2 - 3 x^2)
x y 15 + x y 3 = 18 x y:
-19 y^2 + 18 x y + (16 x^2 - 3 x^2)
16 x^2 - 3 x^2 = 13 x^2:
Answer: -19 y^2 + 18 x y + 13 x^2
Answer: y=1/2x−2
Step-by-step explanation:
i think it is b because i did the question
First, write a statement to define your unknown variable. This is technically not essential to solving the problem, but many teachers prefer to see it.
Example: Let w = the manatee's weight in pounds.
Next, decide what the variable needs to be multiplied by. 12% is equal to 0.12. Usually when a problem says "of," it wants you to multiply. Therefore, 12% of the body weight equals 0.12w. Since the problem already says that this is how much the manatee eats every day, that is your answer.
y = 0.12w
