D+F=N: n is the variable (the sum).
Vertex form is f(x) = a(x - b)^2 + c where the vertex is (b, c) and a is some constant.
So for the first part we have f(x) = a(x + 6)^2 - 1
for root -9:- a( -9+6)^2 - 1 = 0
9a - 1 = 0 , a = 1/9
The other 3 are derived in the same way.
so required equation is f(x) = (1/9)(x + 6)^2 - 1
Divide 25 by 2320 to get $92.80.
3/5 miles = 4 miles
1/5 miles = 4/3 miles
5/5 (1) mile = 20/3 miles = 6 2/3 miles
6 2/3 miles per hour
Answer:
x = 28
Step-by-step explanation:
With 3 angles I'm guessing its a triangle so all triangles equal 180 degrees
42 + 110 = 152
180 - 152 = 28
