Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
1000 gram = 1 kilogram
If 200 gram = $8.12. 1, it means we can get 5 bags of such amount (1000/200 = 5)
Therefore, 1kg = $8.12 * 5 = $40.6
Its also 1/4 because when lines are parallel, this means they have the same slope
Answer:
D) 1pi in^3
Step-by-step explanation:
Volume formula for cylinder is:
V=pi*r^2*h
V=pi*1*1
V=pi in^3
You have a negative exponent so you have to bring the -2 down : 1/-2^3. Then you multiply the -2*-2*-2 which is -8 so you get 1/-8 or -1/8. It means the same thing.
