My father taught me a method that I call, 'throwing some thing over the wall'. There is a sample equation for the first picture that shows you how it works. It's a great way to help isolate the variable and I hope that it works for you. The second picture contains the answers I got through the use of this method. I'm sorry for the messy handwriting; I was on a bus.
Solution
-3b + 11 = -18 + 8b
-3b - 8b = -18 - 11
-11b = -29
b = 29/11
Answer:
3.14 = pi
1.) R = 1.5 and A = 7.065
2.) D = 28 and A = 615.44
3.) R = 10 and A = 314
Step-by-step explanation:
R = 0.5×d
Area of circle = π×r²
X intercept-(9,2/0)
y intercept-(0,-9)
hope this helps
<span>A chord to a circle is any straight line which starts from one point on the circumference to another. For the given circle, the chords of the circle are AD and BE. Therefore, the correct option from the options is option B.Hope I helped! :) Cheers!</span>
