For part a: you just need to find how far the vertex has been moved from the origin, or the point (0,0). As the vertex is at the point (2,-3), it has been translated right 2 horizontally and down 3 vertically.
For part b: you use the info found in part a to create the equation in the form of y=A(x-h)^2+k. In this case, A =1, so you can ignore it. The h value is the horizontal distance the vertex has been moved. Since it has been moved right 2, this part of the equation would be (x-2). I know it seems like it should be plus 2, but values in parentheses come out opposite. For the k value, find the vertical shift, which is down3, or -3.
Now that you have h and k, substitute them back into the equation.
Your final answer for part b is: y=(x-2)^2 -3.
Answer:
50
Step-by-step explanation:
she starts with 9 plus the 10. so she has 19. Danny takes 4 so she has 15. then she trades so she gets 3 per marble she trades so it's like 15 times 3 which is 45. plus the 7 her parents gave her which is 52 and she gives 2 to her sister. so it's 50
The answer is C.) <span>x^2-10x+25=0 </span>
