Answer:
-1/3x+2y=4
Step-by-step explanation:
Substitute the negative reciprocal.
-1/3x+2y=4
<span>The canyon starts at an elevation of (-14.5). After each year, the elevation drops by (-1.5). The equation that could be written for this, then, would be (-14.5 - 1.5x = -31). First, we could add 14.5 to both sides of the equation to isolate the unknown. This would leave -1.5x = -16.5. Next, we can remove the negative signs so both sides of the equation are positive and easier to work with. This leaves 1.5x = 16.5. Finally, dividing both sides by 1.5 gives us "x = 11", which means that after 11 years, the canyon floor will be at -31 feet.</span>
Answer:
10.63cm
Step-by-step explanation:
The formula for calculating the distance between two coordinate is expressed as;
D = √(x2-x1)²+(y2-y1)²
Given the coordinates (3, -1) and (-5, 6)
D = √(-5-3)²+(6-(-1))²
D = √(-5-3)²+(6+1)²
D = √(-8)²+(7)²
D = √64+49
D = √113
D = 10.63cm
Hence the shortest distance between P and Q is 10.63cm
