Answer:

Step-by-step explanation:

Downstream. In water, the direction along the stream is called downstream.

Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr

Y=–6x+2<br> –12x – 2y=–4<br> How many solutions does this linear system have?
DerKrebs [107]

The linear equation y = -6x + 2; -12x - 2y = -4 has no solution

<h3>Linear equation</h3>

y = -6x + 2

-12x - 2y = -4

  • Substitute y = -6x + 2 into (2)

-12x - 2y = -4

-12x - 2(-6x + 2) = -4

-12x + 12x -4 = -4

-12x + 12x = - 4 + 4

0 = 0

  • Solve for x

y = -6x + 2

y - 2 = -6x

x = (y - 2) / -6

  • Substitute into (2)

-12x - 2y = -4

-12(y- 2)/ 6 - 2y = -4

(-12y + 24) / 6 - 2y = -4

-2y + 4 - 2y = 4

0 = 0

X°and x+2 are complementary angles then find the angles<br>​
Elanso [62]

Answer:

44° and 46°

Step-by-step explanation:

Complementary angles sum to 90° , thus

x + x + 2 = 90

2x + 2 = 90 ( subtract 2 from both sides )

2x = 88 ( divide both sides by 2 )

x = 44

Thus the 2 angles are 44° and 44 + 2 = 46°
