The answer should be 6.80
C my friend had this test, if im wrong im super sorry.
I think the answer is for A the explanation is that x represent the amount of time or second that you spend in an elevator and y represent the numbers of floors that the building have.
Answer:
C24
Step-by-step explanation:
You start by taking 41 and 22.
Take 9 from both numbers to represent the students taking both courses.
41-9=32
22-9=13
Then 78-32(French Students)-13(German Students)-9(Two Course Students)
78-32-13-9=
78-54=
24
The answer would be 4
Example- The degree is the term with the greatest exponent.
Recall that for y2, y is the base and 2 is the exponent.
More examples showing how to find the degree of a polynomial.
Example #1: 4x2 + 6x + 5
This polynomial has three terms. The first one is 4x2, the second is 6x, and the third is 5.
The exponent of the first term is 2.
The exponent of the second term is 1 because 6x = 6x^1.
The exponent of the third term is 0 because 5 = 5x^0.
What? 5x^0 = 5?
Well, anything with an exponent of 0 is always equal to 1.
Thus, 5x^0 = 5 × x^0 = 5 × 1 = 5
Since the highest exponent is 2, the degree of 4x^2 + 6x + 5 is 2.
