Answer:
6
Step-by-step explanation:
55 mph minus 40 mph = 15 miles distance for each hour
So 5 hours * 15 = 75 miles difference after 5 hours
Answer:
The first choice.
Step-by-step explanation:
There are no real square roots of numbers < 0
so the domian is all real numbers greater than or equal to zero.
Answer:I would add 3x on both sides because it would allow you to have a positive variable saving you time and effort.
Step-by-step explanation:7=7x-9
A polynomial is made up of terms.
A term is a single number or a number multiplied by one or more variables.
A polynomial can be a single term or a sum of terms.
In a polynomial, there is no division by variables.
Polynomials: Options 1, 2, 4, 5, 6
Not a Polynomial: Option 3
If the terms have at most a single variable, then if the highest exponent on a variable is a 2, then the polynomial is quadratic. If there is only a single variable with no exponent, then it is linear.
Option 1: quadratic
Option 2: linear
Option 3: not a polynomial
Option 4: linear
Option 5: quadratic
Option 6: linear
