oh, you may have forgotten to add the file, you can edit and add it, which i will edit my response and respond.
Step-by-step explanation:
Step-by-step explanation:
can't really use the Pythagorean because you don't know this is a right triangle.
use the fact that they are similar
so
3/6 = x/12 where x is FE
cross multiply
6x = 36 therefore FE = 6
then 6/12 = y/9 where y is FD
cross multiply
12y = 54 = 54/12 therefore FD = 4.5
Answer:
No
Step-by-step explanation:
Plug in (-2, -6) to see if it's the solution or not
3(-2) + 18(-6) ? -14
-6 + ( -108) ? -14
-114 ≠ -14
Answer is NO
Answer:
3,-3,5,-3, the second and fourth are the same
Step-by-step explanation:
Answer:
(x-2)^2+ (y+3)^2 = 64
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2+ (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x-2)^2+ (y- -3)^2 = 8^2
(x-2)^2+ (y+3)^2 = 8^2
(x-2)^2+ (y+3)^2 = 64
