Find the greatest possible value for a+b+c+d if b is a positive integer and a,b,c,d satisfy the system of equations

snow_lady [41]

Answer:

$a+b+c+d = -5\cdot b$

Step-by-step explanation:

The given system of equations is now reduced:

1) $a+b = c$ , $b+c = d$ , $c+d=a$ , $b > 0$ Given

2) $a = c+d$ By 1)

3) $(c+d)+b=c$ 2) in 1)

4) $d = b + c$ By 1)

5) $[c+(b+c)]+b = c$ 4) in 3)

6) $2\cdot b + 2\cdot c = c$ Algebra

7) $c = -2\cdot b$ Algebra

8) $d = -b$ 7) in 4)/Algebra

9) $a = -3\cdot b$ 7) and 8) in 2)/Algebra

10) $a+b+c+d = -5\cdot b$ 9), 1), 7) and 8)/Algebra/Result

<h2>The crime gets cleaned up at 2:00 PM</h2>

Step-by-step explanation:

Let the work be w.

Batman can clean up all of the crime in Gotham City in 8 hours working alone.

$\texttt{Rate of batman,}r_b=\frac{W}{8}$

Robin can do the same job alone in 12 hours.

$\texttt{Rate of Robin,}r_r=\frac{W}{12}$

Robin starts work at 8:00 AM and Batman Joins at 10:00 AM.

Let the time of completion of work after Batman's joining be t.

We have time of working of Robin = t + 10:00 -8:00 = t + 2

$t\times \frac{W}{8}+(t+2)\times \frac{W}{12}=W\\\\12t+8t+16=96\\\\20t=80\\\\t=4hours$

After 4 hours of 10:00 Am work gets completed.

Time = 10:00 AM + 4 hours = 2:00 PM

The crime gets cleaned up at 2:00 PM

1/3 because only 1 and 2 is less than 3 out of the 6 numbers. 2/6 = 1/3.

Write the equation of circle b with center B(-2,3) that passes through (1,2)

professor190 [17]

Answer:

$(x+2)^2 + (y-3)^2 = 10$

Step-by-step explanation:

The standard equation for circle is

$(x-a)^2 + (y-b)^2 = r^2$

where point (a,b) is coordinate of center of circle and r is the radius.

______________________________________________________

Given

center of circle =((-2,3)

let r be the radius of circle

Plugging in this value of center in standard equation for circle given above we have

$(x-a)^2 + (y-b)^2 = r^2 \ substitute (a,b) \ with (-2,3) \\=>(x-(-2))^2 + (y-3)^2 = r^2 \\=>(x+2)^2 + (y-3)^2 = r^2 (1)$

Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.

Plugging in the point (1,2 ) in equation 1 we have

$\\=>(x+2)^2 + (y-3)^2 = r^2 \\=> (1+2)^2 + (2-3)^2 = r^2\\=> 3^2 + (-1)^2 = r^2\\=> 9 + 1 = r^2\\=> 10 = r^2\\=> r^2 = 10\\$

now we have value of r^2 = 10, substituting this in equation 1 we have

Thus complete equation of circle is $=>(x+2)^2 + (y-3)^2 = r^2\\=>(x+2)^2 + (y-3)^2 = 10$
