So for this, replace the x variable with 12 to solve:
EXPLANATION
Drawing the line y=3 give us the following graph:
Reflecting over the axis y=3 give us the following image points:
A' = (-4,2)
B' = (-2,-2)
C' = (-1,0)
D' = (-2,2)
E' = (-4,2)
F'= (-5,0)
Drawing the points in the graph calculator:
Answer:
3.2
Step-by-step explanation:
3.2t when t=1
replace t with 1 so 3.2(1)
hence =3.2
Answer:
x = -1.5
Step-by-step explanation:
16x - 5 = 18x -2
Subtract 16x from each side
16x-16x - 5 = 18x-16x -2
-5 = 2x-2
Add 2 to each side
-5+2 = 2x-2+2
-3 = 2x
Divide by 2
-3/2 = 2x/2
-3/2 =x
Answer:
1/3 of they tank can be filled in 20 min. and in 20 min, the pipe fills up 500 liters.
Step-by-step explanation:
So 20 minutes is 1/3 of an hour so it makes sense to say that 1/3 of the tank would be filled up in 1/3 of an hour. Next if the pipe can fill up the tank in 1 hr min then we would have to just divide it by 3 to find how much it can do in 20 min. So 1500/3 = 500 liters in 20 min. (Hope this helps)
