Area of a rectangular yard:
A 1 = L x W = 7 x * 6 x = 42 x²
Area of a pool:
A 2 = r² π = ( 2 x )² π = 4 x² π
A = A 1 - A 2
A = 42 x² - 4 x² π
Answer: B ) 42 x² - 4 x² π

I’m afraid that it is already written in standard form.
There’s nothing you can do any further then that.
Answer:
y = (-1/2) x + 4
Step-by-step explanation:
<u />
<u>Given line</u> has slope 2 so the <u>perpendicular line</u> has the slope is -1/2 because ⊥ lines have their slopes negative reciprocal.
Both lines intersect at (4, 2) so this point belongs to both lines.
→general equation of a line y = mx+b where m = slope, b = y-intercept
→the equation for the line that has slope m = -1/2, is y = (-1/2) x+ b ( we do not know b now but will find it)
→we know that the point ( 4, 2) belongs to this line so the equation works for (x= 4, y= 2), substitute those values in the equation y = (-1/2) x+ b
2 = (-1/2)*4+ b which gives us b = 2+ (1/2)*4= 2+ 4/2 = 2+ 2 = 4
The equation of the line that is perpendicular to a line with a slope of 2 and intersects that line at (4,2) is y = (-1/2) x + 4
