Answer:
The answer to your question is below
Step-by-step explanation:
Equation 4x - 2y = 8 solve for y
First, pass 4x to the right side -2y = -4x + 8
Pass -2 to the right side y = -4/-2 x + 8 /-2
Simplify y = 2x -4 or y = -4 + 2x
I can not see clearly the work of Charlize and Camille, but the one that has the answer shown above is correct.
Hi how are you doing today Jasmine
The trick here is the recognize that the diagonal length of the rectangle is the diameter of the circle.
W = width of rectangle = 4
L = length of rectangle = 3
D = diagonal of rectangle
Using pythagorean theorem, we solve for D.
W^2 + L^2 = D^2
(4)^2 + (3)^2 = D^2
16 + 9 = D^2
25 = D^2
5 = D or -5 = D
Since D is a length, D must be positive. Therefore, D=5.
D = diagonal of the rectangle = 5
Since D is also the diameter of the circle AND the diameter of a circle is twice the radius, we have the following equation :
r = radius of circle = 1/2 D = 1/2 (5) = 2.5
C = circumference
C = 2 pi r = 2 pi (2.5) = 5 pi
Y=1/2+6 would be the correct answer.
