The sentence says the speed can be maintained for no more than 1640 feet.
The "no more" means 1640 feet or less ,so the equation would be d is less than or equal to 1640.
The correct equation is A.
3180 because you divide 31800 by 10
Answer:
Yhe equation that jas the steepest gradient is D
Step-by-step explanation:
look at the numbers infront of the 'x' without looking at the negative sign. The
larger the number the steeper the gradient. Negative gradient only means that it is a downward slope
Answer:
The slope equation of the line AB is 
Step-by-step explanation:
Here, the given points are A (2, 3) and B (7,4).
Now, slope of any line is given as :

or, 
Hence, the slope of the line AB is (1/5)
Now , A POINT SLOPE FORM of an equation is
(y - y0) = m (x - x0) ; (x0, y0) is any arbitrary point on line.
Hence, the equation of line AB with slope (1/5 ) and point (7,4) is given as:

or, 5y - 20 = x -7
⇒ x - 57 + 13 = 0 ( SIMPLIFIED FORM of equation)
Hence, the slope equation of the line AB is
