Answer:
The number of cards Frank has is 18 and the number of cards his friend has is 24.
Step-by-step explanation:
<u><em>The correct question is </em></u>
Two friends are collecting cards. Frank has 6 more than half the number of cards as his friend. Together they have 42 cards. How many cards does each friend have?
Let
x ----> the number of cards that Frank has
y ----> the number of cards that his friend has
we know that
Together they have 42 cards
----> equation A
Frank has 6 more than half the number of cards as his friend
---> equation B
Solve the system by substitution
Substitute equation B in equation A
solve for y
<em>Find the value of x</em>
therefore
The number of cards Frank has is 18 and the number of cards his friend has is 24.

First, let's find g(4). After we find it, we can substitute the value into 
.
To find g(4), we need to substitute x = 4 into the function 
, as shown below:
Now that we have found g(4) = 9, we can substitute this value in for 
in .
f(g(4)) is equal to 28.
Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
