Answer:
Step-by-step explanation:
we know that
The length of segment B''C'' is equal to the length of segment BC multiplied by the scale factor
step 1
Find the length of segment BC
the formula to calculate the distance between two points is equal to
we have the points
B(1,-3),C(-3,-3)
substitute the values
The segment B''C'' is equal to the segment BC multiplied by the scale factor
The scale factor is 3
so
substitute
First of all, expand the left hand side:
Sum like terms:
Add 3 to both sides:
Subtract 3x from both sides:
So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.
