We have to find the quotient :
( 4 x³ y + 12 x² y³ - 20 x y ) / ( 4 x y ) =
= 4 x y ( x² + 3 x y² - 5 ) / ( 4 x y ) = ( Then 4 x y will be cancelled )
= x² + 3 x y² - 5
Answer:
D ) x² + 3 x y² - 5
Answer:
1) 3 miles/h
2) 3 miles
Step-by-step explanation:
6 miles/2h = 3 miles/h
4h = 12 miles
3h = 9 miles
12 - 9 = 3
Y = a sin b x
amplitude = a
period = 2π /b.
<span>y = 6 sin x
a = 6
b = 1
</span>
a, the amplitude, represents the highest point a graph reaches;
a = 6
The period represents the length of a cycle-
the period = 2π /b = 2π/1 = 2π
Answer:30 papers
Step-by-step explanation:
if he works one day that means he makes $10 , which leaves $15 , divide $15 by $0.50.
that gives you 30 papers
Dedra:
y = 2 + 3x
Nick:
y = 6 + x
Where 'y' is the total cost, and 'x' represents the number of hours.
Solve using substitution, we can substitute 2 + 3x for 'y' in the 2nd equation.
y = 6 + x
2 + 3x = 6 + x
Subtract 2 to both sides:
3x = 4 + x
Subtract 'x' to both sides:
2x = 4
Divide 2 to both sides:
x = 2
Now we can plug this into any of the two equations to get our 'y' value.
y = 2 + 3x
y = 2 + 3(2)
y = 2 + 6
y = 8
So our full solution is (2, 8).
Which means they both bowled for 2 hours, and spent <span>€8.</span>
