(m+2)(m+3)= (m+2)(m-2)
⇒ m^2+ 3m+ 2m+ 6= m^2 -4
⇒ 5m+ 6= -4 (m^2 on both sides cancels out)
⇒ 5m= -4-6
⇒ 5m= -10
⇒ m= -10/5
⇒ m= -2

The final answer is m=-2~

Determine the approximate ordered pair for f(x) = g(x). the graph of two linear functions negative 4 times x plus 15 times y equ

Answer:

(x, y) ≈ (2.848, -19.241)

Step-by-step explanation:

I find it much easier to work with the problem statement when math expressions are written using numbers and symbols. We assume you have ...

-4x +15y = -300

20x +4y = -20

Dividing the second equation by 4 and subtracting the x-term gives ...

y = -5-5x

Substituting that into the first equation, we get ...

-4x +15(-5-5x) = -300

-79x -75 = -300

x = -225/-79 = 2 67/79 ≈ 2.8481

Substituting this into the equation for y gives ...

y = -5(x +1) = -5(3 67/79) = -19 19/79 ≈ -19.2405

The approximate solution is ...

(x, y) = (2.8481, -19.2405)
