18(2a-b)-4(2a-b)-13
=36a-18b-8a+4b-13
Rearrange
=36a-8a-18b+4b-13
=28a-14b-13
Answer:
11 miles an hour
Step-by-step explanation:
44 miles divided by 4 hours would equal 11 miles in one hour, meaning her average speed would be 11 miles an hour
Here the graph y=x²
Taking the 1st derivative here of the y it will be
y1 = 2x
m=-1/3
That is m=2x
so x=-1/6
so y=(-1/6)²=1/36
So the coordinate of point will be=(-1/6 , 1/36)
Answer: y= -1/2x + 5/2
Step-by-step explanation:
3x = 15 -6y
+6y + 6y
3x +6y =15
-3x -3x
6y= 15-3x divide both sides by 6
y= 15/6 - 3/6x
in slope intercept form us y= -3/6x + 15/6 in simplest form is y= -1/2x + 5/2
18;45 = 9
24;16 = 8
