B. Because the band director is 1 then 4 times it said three band members so 3+3+3+3=12+1=13
So in the answer in point form is (2,5)
And in equation form it should be
X=2, y=5
45 / 5 = 9 kg per hr
for 7 hrs.......9 * 7 = 63 kg <==
Answer:
5.8
Step-by-step explanation:
Plug in the x and y values
4(1/2)^2 -3(-5)
Apply the exponent so (1/2)^2 or 1/2 • 1/2 which is equal to 1/4
Now you have 4(1/4) -3(-5)
Multiply them out:
4(1/4)=1
-3(-5)=15 [remember a negative times a negative equals a positive]
So now your equation is 1-15
your answer is 1-15= -14
