Answer:
All of them
Step-by-step explanation:
All we have to do is replace the x and y with their following coordinates
A.(5, -5/6) - - > 5(5) + 12(-5/6) = 25 + (-10) = 15
15 = 15
Yes
B. ( -3, 5/2) - - > 5(-3) + 12(5/2) = -15 + 30 = 15
15 = 15
Yes
C. (-6, 15/4) - - > 5(-6) + 12(15/4) = -30 + 45 = 15
15 = 15
Yes
D. (-5, 10/3) - - > 5(-5) + 12(10/3) = -25 + 40 = 15
15 = 15
Yes
Answer: 14
explanation: work the problem in the smallest parentheses first. 14. now work the longer parentheses. 14/7=2. now multiply it by 7. 2x7=14

Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y
