In which we have
Q(-4,5)=(6+x/2) , (2+y/2)
-4=6+x/2 and 5 =2+y/2
-8=6+x and 10=2+y
x=-14 and y=8
Therefore the required value of R{-14,8}
Answer: 2/3 cups a minute
Step-by-step explanation: If Brayden is adding 1/3 cups of flour to the mixture every 1/2 minutes, you double the 1/2 minutes to get one minute and since you doubled the 1/2 minutes you must double the 1/3 getting 2/3 cups a minute.
11.5% × 350 =
(11.5 ÷ 100) × 350 =
(11.5 × 350) ÷ 100 =
4,025 ÷ 100 =
40.25
If the question was -20.48 divided by -4 then the answer is 5.12
