Answer:
(2x+1) -(-x^2+3x)
Step-by-step explanation:
r(x) = –x² + 3x
s(x) = 2x + 1
find the difference of (s-r)(x)
(s- r)(x) = s(x) - r(x)
we are given with s(x) and r(x)
to find the difference we plug both functions
(s- r)(x) = s(x) - r(x)
distribute negative sign inside the parenthesis
(2x+1) -(-x^2+3x) is the way we find difference
Answer:
$63
Step-by-step explanation:
let x represent Charity B then Charity A = 5x
Sum the two and equate to 378, that is
x + 5x = 378
6x = 378 ( divide both sides by 6 )
x = 63
Thus Charity B received $63
Answer:
Step-by-step explanation:
the balloon starts at (10, 0 )
it ends at 16,0)
in the middle it's at between 10 and 16 , so say about 13, where it reaches 27
so in the middle it's (13,27)
so ( 11, 9)
(12, 18)
got 13
(14, 18)
(15, 9)
got 16

Answer:
0.5656854249
Step-by-step explanation:
1000(0.0128/200)
1000(0.11314/200)
1000(0.0005656854)
=0.5656854249
Answer:
Area of 23958
Step-by-step explanation:
