Get the equation of the line containing PQ using the point-slope formula:

<em>y</em> - (-2) = 3/2 (<em>x</em> - (-6))

Solve for <em>y</em> to get it in slope-intercept form:

<em>y</em> = 3/2 <em>x</em> + 7

so the <em>y</em>-intercept is (0, 7).

The line containing QR is then

<em>y</em> - 7 = -3/4 (<em>x</em> - 0)

or

<em>y</em> = -3/4 <em>x</em> + 7

The point R is on the <em>x</em>-axis, so its <em>y</em>-coordinate is 0. Plug in <em>y</em> = 0 and solve for <em>x</em> to get the other coordinate:

0 = -3/4 <em>x</em> + 7

3/4 <em>x</em> = 7

<em>x</em> = 4/3×7 = 28/3

So the point R has coordinates (28/3, 0).

What is the sum of the matrices shown below?
Georgia [21]

Answer:

\red{ \bold{\begin{bmatrix}  - 4 & 26 & - 5  \\ \\6 &  17& - 8\end{bmatrix} }}

Step-by-step explanation:

\begin{bmatrix} 4 & 19 & - 5\\ \\ 7  & 0 & - 14\end{bmatrix} +  \begin{bmatrix}  -8  & 7 & 0\\ \\  - 1  & 17 & 6\end{bmatrix} \\  \\  = \begin{bmatrix} 4 + ( - 8) & 19 + 7 & - 5 + 0\\ \\ 7 + ( - 1)  & 0  + 17& - 14 + 6\end{bmatrix} \\  \\ = \begin{bmatrix} 4  - 8 & 19 + 7 & - 5 + 0\\ \\ 7  - 1  & 0  + 17& - 14 + 6\end{bmatrix} \\  \\ \purple{ \bold{ = \begin{bmatrix}  - 4 & 26 & - 5  \\ \\6 &  17& - 8\end{bmatrix} }}

Langle is so degrees and ove on.
andre [41]

Step-by-step explanation:

perimeter = 332

let the width be 'x'

then, length = 2x+7

perimeter = 2 (length+width)

332 = 2 ( 2x+7 + x )

332/2 = 3x + 7

166 - 7 = 3x

159/3 = x

53 = x

therefore, width (x) = 53

length = 2(53)+7

           = 113
