On a coordinate plane, a line with negative slope goes through (negative 8, 6) and (4, negative 4). A point is at (negative 6, 1

0).
Which is the ordered pair for the point on the x-axis that is on the line parallel to the given line and through the given point (–6, 10)?

Answer:

It is a

Step-by-step explanation:

This is because the slope is -5/6, so if you graph it then the point will come out as 6,0.

Question 9<br> Write the equation of the line passing through (3,-17) parallel to 8x - 7y=87
just olya [345]

Rewriting the equation of the given line in slope-intercept form,

8x-7y=87\\\\-7y=-8x+87\\\\7y=8x-87\\\\y=\frac{8}{7}x-\frac{87}{7}

The slope of the given line is thus 8/7, and since parallel lines have the same slope, the slope of the line we want to find is also 8/7.

Substituting into point-slope form,

y+17=\frac{8}{7}(x-3)\\\\y+17=\frac{8}{7}x-\frac{24}[7}\\\\\boxed{y=\frac{8}{7}x-\frac{143}{7}}

Which matrix equation represents the system of equations?<br><br> {-x+ 2y = 0 <br> y= -2
Snowcat [4.5K]

We are given a system of equations,

\begin{cases}-x+2y=0\\y=-2\\ \end{cases}

This will translate into a 2x2 matrix of coefficients (because 2 equations and 2 unknowns),

\begin{bmatrix}-1&2\\0&1\\ \end{bmatrix}

The matrix will then be applied to the vector (lower dimensions on top),

\begin{bmatrix}x\\y\\ \end{bmatrix}

And the result vector will be whats on the other side of equals sign,

\begin{bmatrix}0\\-2\\ \end{bmatrix}

So to put everything together,

\begin{bmatrix}-1&2\\0&1\\ \end{bmatrix}\begin{bmatrix}x\\y\\ \end{bmatrix}=\begin{bmatrix}0\\-2\\ \end{bmatrix}

Hope this helps :)

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods trai
Flauer [41]

The length of the goods train is 270 meters.

Given that, a goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds.

<h3>What is the distance formula with speed and time?</h3>

Speed is defined as the rate at which an object moves from one place to another in a given interval of time. It is a scalar quantity as it defines only the magnitude not the directions of an object moving. The S.I. unit of speed is m/s.

The speed of a moving object can be calculated as Speed = Distance / Time.

Now, to convert km/h to m/sec multiply the measure by 5/18.

That is, 72 × 5/18 = 20 m/sec

Let the length of the train be x metres.

So, then (x+250) / 26 = 20

⇒x+250=520

⇒x=270 meters

Therefore, the length of the goods train is 270 meters.
