For this case, the first thing you should do is know that dilation is a transformation that is used<em> to lengthen or shorten a geometric figure.
</em>
Geometric figures can be triangles, squares, circles, or any polygon.
There is a point on the plane, at which the dilation begins to be drawn.
This point on the plane is what we know as the center of dilation
.
Answer:
B. the center of dilation
Step-by-step explanation:
-
Step-by-step explanation:
let necklace : x
let earrings : y
x+y=144 -1st eqn
6x+5y=825 -2nd eqn
y=144-X -3rd eqn
substitute eqn into 2nd eqn
6x+5(144-x)= 825
6x +720-5X =825 (expanded)
X = 825-720
X =105
substitute "X=105" into 1st eqn
(105)+y=144
y= 144-105
y=39
1 necklace = 105$
1 pair of earrings = 39$
(to check back: substitute the value into the original eqn)
I actually think its b cause it can't be d (thats obvious) yh........but i might be wrong
