Answer:
15/20
Step-by-step explanation:
4 x 5 = 20
so
3 x 5 = 15
so (sorry for the repetition)
= 15/20
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.
The quotient of 78,600 and 12 is 6,550
