Answer:
4/3
Step-by-step explanation:
-X + 3/7 = 2X - 25/7
2X + X = 3/7 + 25/7
3X = 28/7
3X = 4
X = 4/3
Answer:
7√2 units
Step-by-step explanation:
The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,
Here, x1=-4 and y1=2
x2=3 and y2=-5
Answer:
set two equation of line y=ax+b and y=cx+d
when these two lines are perpendicular to each other, then a*c=(-1)
x-2y=2
=>x-2=2y
=>(1/2)x-1=y
set the answer is y=ax+b
we can know that a/(1/2)=(-1)
=>a=-2
bring a=-2 and(7,-7) in y=ax+b
-7=(-2)*7+b
=>b=7
the answer is y=-2x+7
Answer:
With increase of elevation by 02 mile there is a fall in temperature by degrees
Step-by-step explanation:
Rate of change of temperature is per mile of increase in elevation
Total increase in elevation miles
Hence, change in the temperature with 02 mile of increase of elevation
degrees
With increase of elevation by 02 mile there is a fall in temperature by degrees
