Option C and D is correct .....
collect the like terms:
Solution: x^2-5xy+4y
P.S
get the photo math app. :)
Hope that helps.
No; a domain value has two range values.
x = -2 then y = 1 and 2
they would form a vertical line, which tells us that it's not a function
N = 9
explanation: If you tilt triangle FGH to where it matches triangle PQR, 9 is matched with N.
more help:
Q = G
10.5 = 7
P = F
H = R
4 = 6
9 = N
65/5=13-3=10 27-17=10
72/6=12-1=11 54-43=11
88/8=11-2=9 27-18=9
90/3=30-8=22 34-10=24
So, that makes "90 ÷ 3 − 8 _____ 34 − 10" not equal.
Hope this helps! Stay Safe!
