H = 1/2 * 8 = 4
Answer:
Step-by-step explanation:
start with 0
round 1 : lose 3 1/2
round 2: wins 28 1/2
round 3 : lose 3 1/2
0 - 3 1/2 + 28 1/2 - 3 1/2 =
28 1/2 - 7 =
21 1/2 <==== thats 21 and 1/2 points
Answer:
y = V x2 +2 over 5
Step-by-step explanation:
Answer:
x = 0 or x = 3
Step-by-step explanation:
if f(x) = g(x) then – x2 + 4x + 1 = x + 1
add the like terms
-x^2 +3x = 0
-x (x-3) = 0 then x is either 0 or 3
