Step-by-step explanation:
this is your answer..........
Step-by-step explanation:
Find the 3rd angle in the triangle, let's call it y
36 + 73 + y = 180
109 + y = 180
y= 71
y is equivalent to x by vertical angles theorem
x= 71
2nd way
Use exterior angles theorem
180 - (36+73) = x
180 - 109 = x
71 = x
I hope this helps!!!
Answer:
-6 is not a whole number..........
Use our brains and what we know
f(x)=a(x-h)²+k
vetex is (h,k)
and a is te leading coefient
if directix is below the focus, then it opens up and a is positive
if directix is above focus, then it opens down and a is negaitve
vertex is in between directix and focus
so
(3,-1) and y=1
-1<1
so directix is above
a is negative
directly in between
distance from -1 to 1 is 2
2/2=1
1 above (3,-1) is (3,0)
vertex is (3,0)
y=a(x-3)²+0
y=a(x-3)²
the only option with a negative 'a' value is B
answer is B
