Answer:
I'm pretty sure it's B
Step-by-step explanation:
Stacy gets 2 cards each week, so you would multiply 2 cards by every week she volunteers. She started out with three cards, so therefore you would add 3.
The units of the initial and final rates of speed are;
<u><em>Initial rate of Speed = ft/hr</em></u>
<u><em>Final rate of speed = mi/min</em></u>
- We are told that the conversion factors he used are;
5280 ft/1 mi and 1 hr/60 min
- Now, the meaning of 5280 ft/1 mi denotes that;
5280 ft mile is equivalent to 1 mile
This means that the initial distance <em>unit </em>used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
- In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.

Answer:
The correct answer is -12
Answer:
(
g
−
f
)
(
3
)
=
23
Step-by-step explanation:
(g-f)(x)=g(x)-f(x)
=6x-(4-X(2))
=x(2)+6x-4
to evaluate (g-f) (#) substitute x=3 into (g-f)(x)
(g-f)=(9)+(6 x 3) -4=23
Hello from MrBillDoesMath!
Answer:
(x+3)^2 -15 = 0
Discussion:
To complete the square add (and then subtract) the square of one-half the coefficient of x:
x^2 + 6x -6 = 0 =>
-- complete the square part --
x^2 + 6x + (6/2)^2 - (6/2)^2 - 6 = 0 =>
x^2 + 6x + 9 - 9 - 6 = 0 => as 6/2 = 3
(x + 3)^ 2 - 9 - 6 = 0 =>
(x+3)^2 -15 = 0
We can solve this as follows:
(x+3)^2 = 15 take square root of both sides
(x+3) = +\- sqrt(15)
x = -3 +\- sqrt(15)
Thank you,
MrB
