Firstly, we will select three corner points
A=(2,3)
B=(6,8)
C=(7,4)
we are given
the transformation with the rule (x, y)→(x, −y)
y--->-y
so, it is reflected about x-axis
so, we will multiply y-value by -1
we get new points as
A=(2,-3)
B=(6,-8)
C=(7,-4)
now, we can locate these points and draw graph
we get
Teacher will have 3 bottles of glue after he combines
<em><u>Solution:</u></em>
Given that,
The art teacher has 7 bottles of glue that are each 2/5 full
He combines them so he will have fewer bottles
<em><u>To find: bottles of glue does he have after he combines them</u></em>
From given,
Total bottles = 7
Each is 2/5 full
Therefore, multiply 7 with 2/5 to get total bottles of glues he will have after combining
Thus teacher will have 3 bottles of glue after he combines
