against the wind a small plane flew 280 miles in 1 hour and 10 minutes. the return trip took only 50 minutes. What was the speed

Amanda [17]

1) 1hour 10minutes = $\frac{7}{6}$ hours,
50 minutes = $\frac{5}{6}$ hours

2) speed of plane against the wind = $\frac{280miles}{ \frac{7}{6} } = \frac{280*6}{7}=240miles /hours$

3) speed of plane on the the wind = $\frac{280miles}{ \frac{5}{6} } = \frac{280miles*6}{5}=336miles/hours$

4) (336-240):2=48miles/hours - speed of wind
5)336-48=288miles/hours - plane's speed <span>in still air

Answer: speed of wind is 48 miles/hours, speed of </span>plane in still air is 288 miles/hours

The graphed line shown below is y=-3x+6

Bezzdna [24]

<h2>Answer:</h2>

$y=-3\left(x+6\right)$

<h2>Step-by-step explanation:</h2>

From the given graph, we can know two points:

$P_{1}(x_{1},y_{1})=(2,0) \ and \ P_{2}(x_{2},y_{2})=(1,3)$

Using the slope intercept form of the equation of a line, we get:

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ y-0=\frac{3-0}{1-2}(x-2) \\ \\ y=-3(x-2) \\ \\ y=-3x+6$

Where the slope is $m=-3$ and the y-intercept is $b=6$

From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:

$y=-3(x+6)$
