Step-by-step explanation:
x + (-7) ≤ 18
x - 7 ≤ 18
x ≤ 18 + 7
x ≤ 25
Value of x is less than or equal to 25
By substitution,
1.5x - 6 = -4.5x + 21
6x = 27
x = 4.5
Hence, y = 1.5(4.5) - 6 = 0.75
A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.
Step-by-step explanation:
Two Circles are said to be similar if all the linear measurements of the circles are proportional.
Lets consider if two circles have a certain ratio of their radii, , it definitely mean that all the other corresponding ratios will also have that same ratio.
<u>Concentric circles are defined as the circles which have a common center. The area between the two concentric circles having difference in their radii is Known as annulus.</u>

The most important property of a circle is that all points on the circle are equidistant (i.e. having the same distance) from the center point.
<u>A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.</u>
