x+2y=6 subtract x from both sides
2y = -x + 6 divide through by 2
y = -x/2 + 3
y = (-1/2)x + 3
and x-y=3 add y to both sides, subtract 3 from both sides
x - 3 = y
y = x - 3
The radius = 2
Area = pi *(2)^2 = 4pi units^2 = about 12.6 units^2
Circumference = 2 * pi * (2) = 4pi units = about 12.6 units
Here's the graph : https://www.desmos.com/calculator/hgdvgjthgp
5/6 + -4/9 - (-2) =
5/6 - 4/9 + 2 =
5/6 - 4/9 + 2/1 common denominator = 18
15/18 - 8/18 + 36/18 =
7/18 + 36/18 =
43 / 18
The distance from the center to the point on the circle is the radius.....and we can find this using the distance formula......so we have
r = √ [ ( 3 - 3)^2 + ( -2 -2)^2 ] = √ [ 0^2 + (-4)^2 ] = √ 16 = 4
So....the circumference is given by 2 * pi * r = 2 * 3.14 * 4 = about 25.12 units
sinx / 36 = .966/50 multiply both sides by 36
sinx = (36/50)*.966 = 0.69552
To find x, use the sine inverse
sin-1 ( 0.69552) = x = about 44.07°
(-32 s) / 4 - 3s = 22 multiply each term by 4
-32s - 12s = 88 simplify
-44s = 88 divide both sides by -44
s = -2
Surface Area = pi [ r^2 + r √(r^2 + h^2) ] where r is the radius and h is the height
If you are just given the radius, r, and the slant height, L, the formula is :
pi [ r^2 + r * L ]
We can use the sine for this......
sin(35) = 40 / D where D is the distance.....rearrange this......
D = 40 / sin(35) = about 69.7 ft.
19 / 12 = 43,121,085 / B where B = Barry's vote.....cross-multiply
19B = 12 * 43,121,085
B = 12 * 43,121,085 / 19 = about 27,234,369 votes
-6n > 54 divide both sides by -6 and reverse the inequality sign
n < -9
