Answer:
mATH IS DONE
Step-by-step explanation:
Again same here, isolate the y variable to get it in y=mx+b form
6y=2x+15 divide by 6 to isolate the y and your equation is...
y=1/3x+15/6. Or 15/6 can be simplified to 5/2.
Answer:
(3x - 2)*(3x + 2)
Step-by-step explanation:
I don't know how much more i can explain, except that you could use the quadratic formula to get your zeroes and then put it in your answer. But this one is obvious. Whenever there isn't an x term and you're subtracting the constant term, it's usually (ax - b)(ax + b)
We need to solve for the radius. So using the "formula" for the surface area, we have
900*pi ft^2 = 4*pi*r^2 divide by pi
900 ft^2 = 4*r^2 divide by 4
225ft^2 = r^2 take the square root of each side
15 ft = r
This should give you tools to answer all the questions.
