Multiply 1/4 (4r -12) = r-2
r-3 = r-2
Subtract r from each side
-3= -2 this equation has no solution
Answer:x=14.333
Step-by-step explanation:
Reflection that will produce an image with endpoints is y=-x
We are given to check
whether these numbers are proportional
we know that any set of numbers are proportional when their ratios are equal
so, firstly we will ratios
First set of numbers:
We are given first set of numbers as 15 , 20 and 30
so, it's ratio is
now, we can simplify it
Since, common factor is 5
so, we can cancel 5
and we get
Second set of numbers:
We are given first set of numbers as 24 , 32 and 48
so, it's ratio is
now, we can simplify it
Since, common factor is 8
so, we can cancel 8
and we get
We can see that both sets of numbers are having same ratios
so, they are proportional.........Answer
The last choice is the answer. y=-3x
