What is the slope of the line with the equation y-3=-1/2(x-2)?
torisob [31]

Answer:  -\frac{1}{2}

Step-by-step explanation:

y -3 = -\frac{1}{2}(x-2)

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

y-3=-\frac{1}{2}x + 1

     y = -\frac{1}{2}x+4

Therefore, the slope is -\frac{1}{2}.

Find the surface area of the composite figure.
ELEN [110]

Answer:

644cm^2

Step-by-step explanation:

First we'll work out the surface area of the pink figure.

That's the area of the two 5 by 6 rectangles on the top and bottom, plus the area of the two 5 by 20 and two 6 by 20 rectangles on the sides.

However, we note that the purple figure is blocking out a 6 by 12 section on the pink figure, so we'll need to subtract this.

The above works out to 2\times(30+100+120)-72=428 cm^2.

Then we'll work out the surface area of the purple figure.

This will be the area of the two 4 by 6 rectangles at the top and bottom, plus the area of the two 4 by 12 and one 6 by 12 rectangles on the sides. Note that there's only one 6 by 12 rectangle because the other face is joined to the pink figure, so it's blocked out.

That's 2\times(24+48)+72=216cm^2.

So the total surface area is 428+216=644cm^2.
