Subtract 4 from both sides and get x=8
Answer:
Figure ABC is congruent to figure A’B’C’.
Step-by-step explanation:
Any figure transformed by a rigid transformation is congruent
The mode is whichever one has the most so the mode would be 7. And the range is the highest number to the lowest. So 9-4 which is 5
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

Next, now that we have the value of y, substitute it into either equation to solve for x:

<u>And this is how you get your final answer (5,2).</u>
