Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.

Step-by-step explanation:
Subtract 7-2=5.
Answer:
Remember, 
Then,
,
Now, using long division of polynomies we have that
The answer is C. (16, 7)
due to every x is incremented by 10
and every y is incremented by 3
the position of T is (6, 4) so the position of T' becomes (6+10, 4+3) which is (16, 7)
