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.
6[5x(41-36) - (8+14)]
6[5x(5) - 22]
6[25x - 22]
150x - 132
Answer:
Total prepared = 5 kg (previously prepared)+ 5 kg prepared in 5 hrs = 10 kg
Step-by-step explanation:
1 kg/hr × 5 hr = 5 kg dough prepared in 5 hours (This is Erica has prepared in 5 hours)
Total prepared = 5 kg (previously prepared)+ 5 kg prepared in 5 hrs = 10 kg
