Question 1:To change the new image back into the original image, just do the opposite.
To change the original image to the new image, we added x by 3 and subtracted 7 from y.
To change the new image back to the original image, subtract x by 3 and add 7 to y.
Writing this into an equation gives us the following:
Question 2:An isometry is a transformation of an image where the new image is congruent to the preimage.
The second and third choices are incorrect because the preimage is not congruent to the new image in these two choices.
The fourth choice is incorrect because having the same position is not an isometric transformation.
Thus, the answer is the first choice.
the 3rd answer should be the correct one
Answer:
12 ft
Step-by-step explanation:
we know the areas of the 2 top squares.
the area of a square is simply the square of its side length.
=>
81 ft² means side length is 9 ft.
225 ft² means side length is 15 ft.
these are also 2 of the sides of the right triangle.
the third side we get by using Pythagoras :
c² = a² + b²
with c being the side opposite of the 90 degree angle.
so,
225 = 81 + x²
as x is also the third side of the triangle.
=> 144 = x²
x = 12 ft
You have 2 apples, get 3 more, and then lose 2 of them.
So, you HAVE 2 apples, and if you get 3 more, you can add it to the 2.
In total at the moment, you have 5 apples. Now, you lose 2 more. We can subtract that from our total number of apples.
We now know that you are left with
3 apples.
