Answer:
$244
Step-by-step explanation:
f(x) = 60x + 4 and g(x) = 2x-4
We are told to find f(g=4), when Mike makes four tables.
We have to put replace x in f(x) with the value g(x) when x is 4, like this:
f(x) = 60x + 4 // Replace x with g(x) = 2x-4
f(x) = 60(2x-4) + 4
f(x) = (120x - 240) + 4 // Solve
f(x) = (120*4 - 240) +4 // They tell us x=4
f(x) = 480 - 240 + 4 = $244

Answer:
(5,-5)
x=5
y=-5
Step-by-step explanation:
How to solve using elimination method.
First, add the two equations.
2x - 3y = 25
+ <u>5x + 3y = 10</u>
7x=35
The y values got eliminated.
Next, divide 7 from both sides.
7x/7=35/7
x=5
Next, plug-in x=5 into one of the equations.
2(5) - 3y = 25
10-3y=25
Subtract 10 from both sides.
-3y=15
Divide -3 from both sides.
y=-5
Remember a positive divided by a negative is a negative.

Answer:
They are all equal and identical in form; coinciding exactly when superimposed.
Step-by-step explanation:
A=P(1/2)^(t/h)
P=initial amount
t=time
h=half life
A=final amount
so
A=0.242188 grams
