C(-1,6);y=2/5x-2 what is the equation of the parallel lines.
1 answer:
9514 1404 393
Answer:
y = 2/5x +32/5
Step-by-step explanation:
The given line is in slope-intercept form.
y = mx + b . . . . . . m is the slope; b is the y-intercept
The value of the slope in the given line is m=2/5. A parallel line will have the same slope. In general, it will have a different y-intercept. That value can be found from the given point.
y = 2/5x + b
6 = 2/5(-1) +b
6 +2/5 = b = 32/5
The equation of the parallel line through (-1, 6) is ...
y = 2/5x +32/5

it consists of a rectangle, dimensions L = 4ft and W = 3ft = Ar = 4ft x 3ft = 12 ft^2
</span>then, you have one half of the area of the circle that has diameter R = 3ft - radius will be r = 1.5ft the area of that half will be:
Ac = r^2
/ 2
= (1.5 ft)^2 x 3.14 / 2
= 2.25 ft^2 x 3.4/2
= 7.065 ft^2/ 2
= 3.5325ft^2
A = Ar + Ac
A = 12ft^2 + 3.5325ft^2
A = 15.5325ft^2
