3280.839895 ft = 1 km
60 ft = 60/3280.839895 = 0.018288 km
60 ft/s = 0.018288 km/s = 0.018288 x 60 x 60 = 65.8368 km/h
First, you have to convert 1/4 and 1/3 to have the same denominator.
So, 1/4 x 3 = 3/12. 1/3 x 4 = 4/12.
Now, you can add 3/12 + 4/12 = 7/12.
A. y=2x
because slope-intercept form is y=mx+b. m= slope & b= y-int. The y-int is at the origin, so therefore y=0. The slope is 2, so therefore the answer is y=2x
