Answer:
7
Step-by-step explanation:
To find the degree of a polynomial you must find the term with the highest degree.
First, you must identify each term in the polynomial. In this problem there are two terms 2x^3 y^4, and -7x^2 y^3.
If there are multiple variables in the terms, like in this equation, you will add the exponents within the term.
For the term 2x^3 y^4 you will add the exponents 3 and 4 (3+4=7). The sum of the exponents is 7 meaning this term has a degree of 7.
For the term -7x^2 y^3 you will add the exponents 2 and 3 (2+3=5). This term has a degree of 5.
Since the highest degree term is 7, the degree of polynomial is 7.
Answer:
The train eingineer.
Step-by-step explanation:
So, to find the lifetime income, we must multiply the annual income by the years of work.
So for the cran operator:
54,830*30
=
1,644,900
Now lets compare this to the train eingineer:
50,610*33
=
1,670,130
So looking at the two numbers:
<u>1,670,130(train eingineer)</u>>1,644,900(crane operator)
So the trian eignineer makes more than the crane operator.
Now lets find the amount.
To do this, lets subtract the larger value by the smaller value:
1,670,130-1,644,900
=
<u>25,230</u>
So the train eingineer made 25,230 more dollars than the crane operator.
Hope this helps!
I think it’s C because 20-11 is C xD
Rearrange: 2y = 6 -3x
2y = - 3x + 6
y = -1.5x + 3
Now, substitute, perpendicular lines have the same gradient so:
-1 = -1.5 (2) + c
- 1 = -3 + c
2 = c
equation for new line: y = 1.5x + 2
3.
1000 miles per month.
12 months in a year.
1000 × 12 = 12000 miles per year
Oil change every 4000 miles.
12000 ÷ 4000 = 3
Therefore 3 oil changes per year.
