It's dependent on the context. A book may ask you to find the f'(x) of a function and you may have to use a u sub in your problem which requires you to find the dy/dx of what you substitute. So in this case both would be used.
1/12
This is because there are 12 potential outcomes of this scenario. Tails, 5 is just one of them.
Use a tool called a protractor
Step-by-step explanation:
There are infinitely many such integers.
x - y = -6 <em>add y to both sides</em>
x = -6 + y → x = y - 6
1. Choose any y value.
2. Substitute for the equation.
3. Calculate the value of x.
Examples:
for y = 0 → x = 0 - 6 = -6
check: -6 - 0 = -6
for y = 10 → x = 10 - 6 = 4
check: 4 - 10 = -6
for y = -9 → x = -9 - 6 = -15
check: -15 - (-9) = -15 + 9 = -6
