Answer:
a=1
b=4
c=-1
Axis of cemetry and vertex:x=-2
Step-by-step explanation:
x=-b/2a
x=-4/2(1)
x=-2
Answer:
f(-1) = -3
Step-by-step explanation:
(Assuming {2} is ^2)
f(-1) = 3(-1)² + 4(-1) - 2
= 3(1) - 4 - 2 = -3
Answer: 327 1/3
Step-by-step explanation:
Answer:
w = y - x is the equation to find w
Where,
w = Weight of the liquid
x = Weight of the empty can
y = Weight of the can with liquid
Step-by-step explanation:
Let
Weight of the empty can = x
Weight of the liquid = w
Weight of the can with liquid = x + w = y
x= 30 grams
w = ?
y= 47.3 grams
y = x + w
w = y - x
= 47.3 - 30
= 17.3
w= 17.3 grams
Therefore, the weight of the liquid is 17 .3 grams
17.83 times 1.1
=19.613
17.83+19.613
=37.443
=37.5 dollars
