Answer:15
Step-by-step explanation:
Answer:
It costs $15 a month to play the video game.
The initial cost is $45.
The y-variable represents the cost in dollars.
The x-variable represents the number of months.
Step-by-step explanation:
If you break the function down, you're going to have:
<u>Total = Monthly Cost + Initial Cost</u>
In this case, 15x is your monthly cost, as you can think of x as the number of months meaning:
- 15 for the first month (x = 1)
- 30 for the second month (x = 2)
- 45 for the third month (x = 3), and so on
Our initial cost is always going to be a set amount, thus our constant, $45.
This leaves y as our total, which makes sense, as it's all alone on one side of the equation, where as all the costs are bunched together on the right side.
Hope this helps!
Subtract 13 from both sides:
Divide both sides by -5. Since this is a negative number, you have to invert the inequality sign:
Which means
Answer:
2ab(7a^4b^2+ a^5×b-2a)
start with multiple 2ab into the equation
(2ab×7a^4b^2)+(2ab×a^5×b)-(2ab×2a)
((2×7)a^(4+1)b^(2+1))+(2×a^(5+1)×b^(1+1))-((2×2)a^(1+1)×b)
14×a^5×b^3+2×a^6×b^2-4×a^2×b
