5y-15x=-20
5y=15x-20
y=3x-20/3
Slope = 3
Slope Intercept Form
y-y1=m(x-x1)
Therefore y-(-6)=3(x-3)
y+6=3x-9
y=3x-15
Answer:the cost of each CD for a member is $5.25
Step-by-step explanation:
The membership costs $22 per year, and then a member can buy CDs at a reduced price.
Let x represent the cost of each CD for a member.
Let n represent the number of CDs that each member buys. This means that the total cost of buying n CDs for a member for a year would be
22 + nx
If a member buys 17 CDs in one year, the cost is $111.25. This means that
17x + 22 = 111.25
17x = 111.25 - 22 = 89.25
x = 89.25/175 = 5.25
each coind has a 1/2 probability of landing on heads
3 coins would be 1/2 x 1/2 x 1/2 = 1/8 probability
Answer:
0
Step-by-step explanation:
3x+2=2
or, 3x=2-2
or, x=0/3
:. x=0
Answer:
x = 30
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
