What does the value of x have to be so that
Natali5045456 [20]

The value of x is 5

<em><u>Solution: </u></em>

<em><u> The slope of a line is given by formula: </u></em>

Slope = \frac{ y_2-y_1}{x_2-x_1}

From given,

slope = \frac{11}4}\\\\(x_1, y_1) = (x, -7)\\\\(x_2, y_2) = (-1, 4)

<em><u>Substituting the values we ge</u></em><em><u>t,</u></em>

\frac{11}{4} = \frac{4+7}{-1-x}\\\\-11 - 11x = 11 \times 4\\\\-11-11x = 44\\\\11x = -11-44\\\\11x = 55\\\\x = 5

Thus the value of x is 5

SOMEONE PLEASE HELP ME ASAP PLEASE!!!​
Nostrana [21]

Answer:

<h2>y=<u> -2</u>x+<u>7</u></h2>

<u>Here</u><u>,</u>

Two points given: (3,1) and (7,-7)

slope(m) =  \frac{y2 - y1}{x2 - x1}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{ - 7 - 1}{7 - 3}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{ - 8}{4}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  - 2 \\

Equation of line is y= Mx+b

y= -2x +b

It passes through (3,1)

1 =  - 2(3) + b \\ 1 =  - 6 + b \\  - b =  - 6 - 1 \\  - b =  - 7 \\ b = 7

Equation of line:

<h3>y= -2x+7</h3>

Hope this helps..

Good luck on your assignment..

A man flies a small airplane from Fargo to Bismarck, North Dakota --- a distance of 180 miles. Because he is flying into a head
cricket20 [7]

Answer:

  • Plane = 105 mph and wind = 15 mph

Step-by-step explanation:

Let the plane's speed is p, the wind speed is w.

<u>We have:</u>

  • 2(p - w) = 180 ⇒ p - w = 90
  • 1.5(p + w) = 180 ⇒ p + w = 120

<u>Solve the system by elimination, add up the equations:</u>

  • p - w + p + w = 90 + 120
  • 2p = 210
  • p = 105

<u>Find the value of w:</u>

  • 105 - w = 90
  • w = 105 - 90
  • w = 15
