Answer:
k = 3.75
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, k. Divide -1.2 from both sides:
(-4.5)/(-1.2) = (-1.2k)/-1.2
-4.5/-1.2 = k
k = -4.5/-1.2
k = 3.75
3.75 is your answer for k.

Answer:
d) ordered pairs are equal
e) ordered pairs are not equal
Step-by-step explanation:
d) ( 3+4 , 2 - 1)
x-co ordinate = 3 + 4= 7
y-co ordinate = 2 - 1 = 3
(3+ 4 , 2-1) = (7 , 3)
(3+4 , 2-1) & ( 7 ,3) are equal
f)Compare the x -co ordiante and y - co ordiante of the two pairs
p +q = q + p {addition closed under commutative property}
but q - p ≠ p - q {Subtract is not closed under commutative}
(p +q, q - p) & ( q + p , p -q ) are not equal
9/10=27/30
5/6=25/30
I hope this helps :-)
