The -3 shifts the graph 3 units to the right
and The + 9 moves the graph upwards 9 units
Its B
A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
3 consecutive odd integers : x, x + 2, x + 4
3(x + x + 2 + x + 4) = x(x + 2) + 24
3(3x + 6) = x^2 + 2x + 24
9x + 18 = x^2 + 2x + 24
x^2 - 7x + 6 = 0
(x - 1)(x - 6) = 0
x - 1 = 0
x = 1
x - 6 = 0
x = 6 (this will not work...it is even)
ur 3 consecutive odd integers :
x = 1
x + 2 = 1 + 2 = 3
x + 4 = 1 + 4 = 5
For number 2 problem:
10x=5y
15x=7.5y
20x=10y
For problem3:
3x=1.5y
4x=2y
5x=2.5y
