Answer:
Required equation: 
Length of the main span of the Dames point Bridge = 396 meters
Step-by-step explanation:
Main span of the Sunshine Skyway Bridge = 366 meters .... (1)
Let 
represent the length of the main span of the Dames point Bridge.
It is given that the bridge's main span is 30 meters shorter than the main span of the Dames Point Bridge.
Main span of the Sunshine Skyway Bridge = 
meters .... (2)
From (1) and (2) we get
Add 30 on both sides.
Hence, the required equation is and the length of the main span of the Dames point Bridge is 396 meters.

Answer:
-5
Step-by-step explanation:
(+5) × (-1) can also be written as (-1) + (-1) + (-1) +(-1) +(-1) which is -5
Answer:
y = -7.5 I believe
Step-by-step explanation:
Answer:
I'm pretty sure it's +(-6).
Step-by-step explanation:
Basically for these, you find the slope. The slope equation is y1-y2/x1-x2.
Pick two points.
I'll just do (1,15) and (2,9).
15-9/1-2 = 6/-1 = -6.
I don't know if you were taught it this way, but my math teacher always told us that the rate of change had to be positive.
So you'd say the rate of change is +(-6), not -6.
Hope that sorta helped lol
