Solve the system using elimination

2x + 3y = 9
x + 5y = 8....multiply by -2
----------------
2x + 3y = 9
-2x - 10y = -16 (result of multiplying by -2)
---------------add
-7y = - 7
y = -7/-7
y = 1

x + 5y = 8
x + 5(1) = 8
x + 5 = 8
x = 8 - 5
x = 3

solution is (3,1)

Which phrase best descubes the translation from the graph y = (x - 5)2 + 7 to the graph of y = (x + 1)2 - 2?

Ber [7]

Answer:

"6 units left and 9 units down"

Step-by-step explanation:

Suppose a function is given in this form:

$y=(x-a)^2+b$

This is the parent function y = x^2

translated a units right (left if there was a + before a)
translated b units up (down if there was a - before b)

Now, to go from $y=(x-5)^2+7$ to $y= (x+1)^2-2$ , we can see that:

first function is 5 units right and 2nd one is 1 unit left, so there is a horizontal translation of 6 units left
first function is 7 units above and 2nd one is 2 units down, so there is a vertical translation of 9 units down

Thus, "6 units left and 9 units down" is the transformation(translation).
