Answer:
<h2>what is this ....</h2>
<h3>please properly post the question</h3>
1200 seconds divided by 3600=
0.33333333 of an hour or a third of an hour.
Or just 20 minutes lol
Slope=m=(y2-y1)/(x2-x1)=(-7+3)/(6+6)=-4/12=-1/3
y=mx+b, y=-1/3x+b, -3=(-1/3)*(-6)+b, -3=2+b, b=-5
Answer: y=(-1/3)x-5
Answer: x= -2 and y= -3.
Step-by-step explanation:
The given system of equations :
4x-7y=13 ...(i)
4x + 7y = -29 ....(ii)
By Elimination method, Eliminating (ii) from (i) , we get
Now, Adding (i) and (ii), we get
Hence, the solution is : x= -2 and y= -3.
