The equations is : y=-1/4x -6
The line intercepts the y axis at -6 and from there it is one down and 4 to the right.
Answer:
4 mph
Step-by-step explanation:
The speed downstream is (28 mi)/(2 h) = 14 mph.
The speed upstream is (18 mi)/(3 h) = 6 mph.
The speed of the current is half the difference of these:
(14 mph -6 mph)/2 = 4 mph
_____
The current adds to the downstream speed and subtracts from the upstream speed, so the difference of those speeds is twice the current's speed.
D would be the correct answer.
Explanation
a^2+b^2=c^2
4^2+3^2=c^2

25 units
Answer:
23/4
Step-by-step explanation:
This means that it is 3/4 of the distance in the x <u>and</u> y coordinates, so it is 3/4 of the way from 2 to 7, and since this is a difference of 7-2=5, then it is 2 + (5 * 3/4) or 2 + 15/4 or 23/4.
