X=-6
you could either multiply 9 on both sides or distribute the 9 and isolate the variable
Answer:
6c+30
Step-by-step explanation:
Distribute it!
Let x represent the distance Darren ran.
The distance Darren ran: d
The distance Darren ran plus 4 more miles: d + 4
Answer: d + 4
A) The membership cost starts at $23 and it adds $6 every year. The 23 would be your b and the 6 would be your slope, m, in the form y=mx+b.
y=6x+23
This equation means that you're starting at 23 dollars and adding 6 dollars with every x you add.
B) 2009-1995=14 This means that there's 14 years that the cost increased. 14*6=$84 The membership cost increased by anther $84 over the 14 years. You have to add 84 to 23 to find your total=$107.
C) Set $85 equal to 6x+23
85=6x+23
6x=62
x≈10
10 years later the cost will be $85.
1995+10=2005
