River C is 200 miles longer than River D. If the sum of their lengths is 5580 miles, what is the length of each river?

Valentin [98]

Yo sup??

Let the length of river D be x

then the lenght of river C will be 200+x

but,

lenght of river C+lenght of river D=5580

x+x+200=5580

2x=5380

x=2690

Therefore lenght of river D is 2690 and that of C is 2890

Hope this helps

What is an equation of the line that passes through the point (-3,-1) and is

Yuri [45]

Answer:

y = -2x - 7

Step-by-step explanation:

x - 2y = 6

-2y = -x + 6

Divide the whole equation by (-2)

$\frac{-2y}{-2}=\frac{-x}{-2}+\frac{6}{-2}\\\\y = \frac{1}{2}x - 3$

slope = 1/2

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

$=(-1)*\frac{2}{1}\\\\= -2$

(-3, - 1)

y -y1 = m(x -x1)

y - [-1] = -2(x - [-3])

y + 1 = -2(x + 3)

y + 1= x* (-2) + 3*(-2)

y + 1 = -2x - 6

y = -2x - 6 - 1

y = -2x - 7
