Answer:
( - 6 , - 1 )
Step-by-step explanation:
Let's find the rule of that transformation:
1 + = 4 ⇒ = 3
9 + = 10 ⇒ = 1
Thus, the rule of given transformation is ( x + 3 , y + 1 )
So, the image of the point ( - 9 , - 2 ) is
( - 9 + 3 , - 2 + 1 ) = ( - 6 , - 1 )
12.75 - 11.25 = 1.50
11.25 - 9.75 = 1.50
there is a difference of $ 1.50 in allowance between brothers
that means the 7 yr old is gonna get : 9.75 - 1.50 = 8.25 <==
