50 - 3n = 7n + 80
    +3n     +3n ( add 3n to both sides)
50 = 10n + 80
-80            -80 (subtract 80 from both sides)
-30 = 10n (divide both sides by 10)
n = -3

Slope intercept form is y=MX+b.
M is the slope, x is the x intercept, and b is the y intercept

the slope is
\frac{ - 2}{1}
An intercept is where the formula crosses the axis. therefore, the x intercept is .5, and the y intercept is 1
so the point slope formula is
y =  \frac{ - 2}{1} 0.5 + 1

The figures below are based on semicircles and squares. Find the perimeter and the area of each shape. Give your answer as a com
Nuetrik [128]
To find the area, move each semicircle to fill up the square, you'll see there are three squares, each with an area of 4*4=16, so the total area is 3*16=48
Now the perimeter:
the perimeter of a circle is π times the diameter.
perimeter of each semicircle: (1/2)π*4=2π
there are altogether 6 arches and two straight sides, so the total is
2π*6+4*2=12π+8

the area is 48 square units, the perimeter is 12π+8 units.
