What does the value of x have to be so that

Natali5045456 [20]

The value of x is 5

Solution:

The slope of a line is given by formula:

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

From given,

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

Substituting the values we get,

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

Thus the value of x is 5

SOMEONE PLEASE HELP ME ASAP PLEASE!!!

Nostrana [21]

Answer:

Here,

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:

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.

We have:

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

Solve the system by elimination, add up the equations:

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

Find the value of w:

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