Answer:
-11
Step-by-step explanation:
if you put the numbers of the variebles in, it would be
-6-9+9-5

Step-by-step explanation:
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.
Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
Hi there!
The next step is most likely the following:
3x = 18
This is because you add up 3 on both sides on the equation.
