160 of 200
160/200=0.8
move the decimal point over to the right 2 times
then u have 0.80
80%
Answer:
x=175
Step-by-step explanation:
1st number = x
2nd number = x
3rd number = 1.6(2x)
x+x+1.6(2x)=910
x+x+3.2x=910
5.2x=910
x=175
I think it is 5/6 because you would have to choose a small amount
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.
