Answer:
(b) 9
Step-by-step explanation:
The product of segment lengths to the near and far intersection with the circle is the same for both secants.
4(4+5) = 3(3+x) . . . . the above statement with numbers filled in
36 = 9 +3x . . . . . . . simplify
12 = 3 +x . . . . . . . . divide by 3
9 = x . . . . . . . . . . . subtract 3
Rememer you can do anything to an equaiton as long as you do it to both sides
and the erased answer is correct
10=-6.5+n
add 6.5 both sides
10+6.5=6.5-6.5+n
16.5=0+n
16.5=n
5. Center (-2,3) Radius 3
6. Center (-2,0) Radius √11
7. Center (0,-4) Radius 5
8. Center (3/2,-4) Radius 3√17/2
9. Center (6,8) Radius 4
10. Center (-1,-2) Radius 4
Ive attached what the graphs will look like, I cannot add the last graph since its the image limit for this website.
Hope this helps, feel free to PM me if you are still having trouble and need the last graph :)
You just need to solve for g, multiply it out to get -g+6+2g=-4g-4, subtract 6 from both sides to get -g+2g=-4g-10, then add 4g to both sides for -g+2g-4g=-10, then add the g's together to get -3g=-10, divide both sides by -3 and you get g=3,1,3 (three and one third).
