Answer:

y=\frac{3}{2}x-11

Step-by-step explanation:

We have been given an equation y=-\frac{2}{3}x+5. We are asked to find the equation of line perpendicular to our given equation and passes through point (8,1).

We know that the slope of a perpendicular line to a given line is negative reciprocal of the slope of given line. So the slope of perpendicular line to the line y=-\frac{2}{3}x+5 will be negative reciprocal of -\frac{2}{3}.

\text{negative reciprocal of }-\frac{2}{3}=-(-\frac{3}{2})

\text{negative reciprocal of }-\frac{2}{3}=\frac{3}{2}

Upon substituting m=\frac{3}{2} and coordinates of point (8,1) in slope intercept form of equation we will get,

1=\frac{3}{2}*8+b

1=3*4+b

1=12+b

1-12=12-12+b

-11=b

Therefore, the equation y=\frac{3}{2}x-11 represents the equation of line perpendicular to our given line.

vova2212 [387]

Answer:

IT SHOULD BE 240

Step-by-step explanation:

1) Multiply 20 by 10 for 200

2) Lenght=20 so half is 10

3) multiply 10 by 4 and divide by 2 which gives 20

4) Multiply 20 by 2 because there are 2 rectangles which gives us 40
