Answer:
The expression 
has two variables x and y.
Step-by-step explanation:
<u>What is a variable?</u>
A variable is a letter, for instance 
or 
, that represents an unknown number.
Given the expression
The given expression has three terms which are x, 4y, and -9.
Here:
- The term 'x' is the unknown variable x.
- The term '4y' has a coefficient (the number next to a variable y) of 4.
- The term '-6' is a constant.
As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.
Thus, the expression has two variables x and y.
Answer: b; y intercept between 8 and 4
Step-by-step explanation:
1. a; 2/3
2. b; 3, all real numbers except x=2
3. a; $.75
4. c; intercepting at (-3,-3)
5. b; 5
6. a; starts at 3
7. b; 1975
8. b; y intercept between 8 and 4
2/x ^6-3 you do the opposite of everything
Answer:
D. He forgot to subtract the area of the base from the total surface area of the cube.
