Answer:
(- 3, 5 ) & (-2,7)
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , thus
(5, 3 ) → (- 3, 5 )
Under a counterclockwise rotation about the origin of 90.
a point (x, y ) → (- y, x ) , thus
(7, -2 ) → (-2, 7)
Never. If you rent one hour the difference will be $12 - $10 =$2, if your rent for 2 hours, the difference will be $24 - $20 = $4, and so the difference will grow as the number of hours increase.
10=2×5 and 14=2×7 so least common denominator will be 2×5×7=70
9/10=63/70
3/14=15/70
So 63/70-15/70=48/70=24/35
Answer:
5 gallons
Step-by-step explanation:
We can use ratios to solve
5/12 gallon x gallons
---------------- = -------------------
1/24 minute 1/2 minute
Using cross products
5/12 * 1/2 = x *1/24
5/24 = x/24
Multiply each side by 24
24*5/24 = x/24*24
5=x
We can pump 5 gallons
It is in the 1s place, I believe
