using
log (xy) = log(x)+log(y)
so equal to (log6+log(x))²
Let x =1 loave of bread 's cost
x=48÷24
=2
10 loaves cost
=10x
=10(2)
=20
The answer is 0.2 hope this helps
Answer: f(x) = 7x
See this table
x [ ft^3 of air in the ballon] f(x) [grams that can be lifted]
1 7
2 14
3 21
ANSWER: x=7, y=19
Steps
1. Substitute y=2x+5
3x+2x+5=40
2. For y=2x+5 , Substitute x=7
y=2 * 7+5
3. 2 * 7+5=19
y=19
