What is the solution to the equation 3/m+3-m/3-m=m^2+9/m^2-9

Mathematics
1 answer:
Bas_tet [7]3 years ago
7 0

Answer:

  no solution

Step-by-step explanation:

If we subtract the left side of the equation, we get ...

  \dfrac{m^2+9}{m^2-9}-\dfrac{3}{m+3}+\dfrac{3}{3-m}=0\\\\\dfrac{m^2+9-3(m-3)-3(m+3)}{(m-3)(m+3)}=0\\\\\dfrac{m^2-6m+9}{(m-3)(m+3)}=0=\dfrac{(m-3)^2}{(m-3)(m+3)}\\\\\dfrac{m-3}{m+3}=0\quad\text{m$\ne$3}

This equation will equal zero only if m=3, which is disallowed because it makes the denominator zero. Thus, there is no solution.

Snowcat [4.5K]

Answer:

Rs. 5500

Step-by-step explanation:

The government has declared that farm workers should be paid Rs. 71 for a day's work

The landlord Mohan pays Rahul Rs. 60 and pays Rs. 55 to his wife

Rahul works for 55 days

= 60 × 55

= Rs. 3,300

His wife works for 40 days

= 55 ×40

= Rs. 2,200

Therefore the total amount of money earned together can be calculated as follows

= 3300 + 2200

= Rs. 5500

Hence they will earn Rs. 5500 together

Solve for k <br> J = k^2/4 <br> (There can be multiple answers)
Makovka662 [10]

Answer:

The first option is the answer (k = +/- 2 square root of J)

Step-by-step explanation:

Since you need to leave k by itself, You multiply both sides by 4 which will leave you with 4J=k^2. To get rid of the square(^2), you need to square root both sides which will leave k by it self. So now you have 4J inside the square root = k. The last step is to take the square root of 4 (which is + or -2) and put it outside the square root sign, leaving J inside the square root.

dolphi86 [110]
We know that Heidi has x donations. We also know that Granpa has 2 fewer donations than Heildi, which means to subtract so x - 2.  We also know that there are 7 donations in all. This tells use donations = 7 in all. So

Heidi donations = x
Grandpa = x - 2
Heidi + Grandpa = Total donations

x + (x-2) = 7
