Answer:
5
Step-by-step explanation:
The gradient is the ratio of the change in y to the change in x:
m = ∆y/∆x = (16 -6)/(2 -0) = 10/2 = 5
The gradient of the line segment is 5.
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is 
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become

we can arrange this properly to form a quadratic equation by grouping like terms.

solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
Slope = rise/run
Rise = 3, run = 8
Downwards line = negative
Slope = -3/8
Answer:
45
Step-by-step explanation:
You take 181-119=62 then 119-74=45 then the last one was 74, to check you add them all together and you should get 181, since sofia was the smallest she is 45lbs
(8x + 7) - (2x - 3)
(8x + 7) + (-2x + 3)
combine like terms
8x - 2x and 7 + 3
6x + 10
