Which is true about the degree of the sum and difference of the polynomials 3xy - 2xy4 - 7xy and -8xy + 2x°y4 + xy?O Both the sum and difference have a degree of 6.
O Both the sum and difference have a degree of 7.
The sum has a degree of 6, but the difference has a degree of 7.
The sum has a degree of 7, but the difference has a degree of 6.

Answers

The degree of the sum and difference of the polynomials are 6 and 7 respectively.

The degree of the sum and difference of the polynomials.

3x⁵y - 2x³y⁴ - 7xy³ and -8x⁵y + 2x³y⁴ + xy³

The degree of sum = monomial with the highest power = 5 + 1 = 6

The degree of difference = monomial with the highest power = 3 + 4 = 7

Therefore, the degree of the sum and difference of the polynomials are 6 and 7 respectively.

Answer:

It's C I just did it

Step-by-step explanation:

The earnings, E of a DJ who charges fee of $250 and an additional $40 per hour,h. NEED HELP ASAP

Answers

Given that you say the question doesn't state the duration of work, I suspect it is asking for an equation to describe E in any situation.

Therefore, let's take x to be the number of hours he is working for.

We know he earns a base $250, so E is going to be 250+something.

That something we know is a multiple of the number of hours he is working for. If it is $40 per hour, it is going to be 40x as if x is 1 that gives 40, if it is 2 it gives 80 and so on.

If we substitute this all in we get:

E = 250 + 40x
Where x is the number of hours he works for.

Which expression DOES NOT represent a square root of a perfect integer A. square root of 100
B. square root of 64
C. square root of 81
D.square root of 89

Answers

The answer is D) square root of 89

Explanation:
Since it's asking for a root with a perfect integer, you need to multiply a whole number by itself, answer choice D is the only one that doesn't achieve this.

A- sq rt of 100 is 10
B- sq rt of 64 is 8
C- sq rt of 81 is 9

Younger than = less than

Less than symbol = <

People cannot have a negative age, so a must be positive

B. a < 18 and a must be a positive number

If your cell phone bill was $67.82 and there is a 7% late fee, how much will your bill be?

Answers

about $72.57 because you do 67.82 times .07, which is 4.7474, then add it to 67.82, which is 72.5674. round it to 72.57
