Which expression is equivalent to:1/m6

Mathematics

1 answer:

Valentin [98]3 years ago

8 0

Answer:

Step-by-step explanation:

6 is a power. So both C and D are wrong because 6 is being treated as an ordinary integer.

So the answer must be either A or B.

B is not correct because to move an expression from the denominator to the numerator changes the sign in the base (which is m in this question).

A is correct. the power is changed from 6 in the denominator to -6 in the numerator. m is shifted to the numerator as well.

Find the discriminat 2x^2 + 8x - 9 = 0

alexandr402 [8]

Answer:

2x^2 + 8x - 9 = 0

2x^2 + 8x = 9

2x^2 + x = 9/8

x^2 + x = 9/8×2

x^2 + x = 9/16

2x = √9/16

x = √9/32

Miranda’s financial aid stipulates that her tuition not exceed $1200. If her college charges a $90 registration fee for the term

Arlecino [84]

Answer: the greatest number of courses for which miranda can register is 2

Step-by-step explanation:

Let x represent the number of courses for which Miranda can register.

If her college charges a $90 registration fee for the term plus $475 per course, it means that the total amount that the college charges for x courses would be

475x + 90

Miranda’s financial aid stipulates that her tuition not exceed $1200(it must be at most $1200). This means that

475x + 90 ≤ 1200

475x ≤ 1200 - 90

475x ≤ 1110

x ≤ 1110/475

x ≤ 2.34
