Hello answer asap please! A scale model of the Golden Gate Bridge in San Francisco has a main span that is 284 centimeters long. If the scale of the model is 1 cm : 15 ft, how long is the main span of the bridge?

We can use a proportion, here:

Let x be the main span length

15 ft/ 1cm  =  x ft / 284 centimeters      cross-multiply

284 * 15  = x   = 4260 ft

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
