For the second one the reason for c is it explains the next step when -12+12 which equals 0 and then it shows u the next step
X = 3
Y = 4/3
You solve the problem by substitution method
Answer:
See Attachment for graph
Step-by-step explanation:
Given
Point C
Required
Plot C when dilated by 1/2
First, we have to determine the coordinates of point C
From the attached graph;

Next, is to determine the new point when dilated;
This is calculated as thus;


Expand the bracket



This implies that C' will be plotted at x =0 and y = 3
<em>(See attached for point C')</em>
Answer:
25. a = 60
26. a = 17
Step-by-step explanation:
In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure
so we have
25.

and for 26 we have
