The formula for a vertex form equation is
in which (h,k) represents the vertex
Your equation is in vertex form, if you mpve the -7 to the other side you will get
because you have to add 7 to both sides
based on the equation,
h=10
k=7
(h,k)=(10,7)
your vertex is (10,7)
Answer:
y = -0.4 + c
Step-by-step explanation:
y = mx + c (original form)
m ⊥ - 1/m
2.5 = 25/10
25/10 ⊥ -10/25
-10/25 = -0.4
y = -0.4x + c

Answer: 12/13....Remember the shortcut SOH CAH TOA ——> sin = opposite/hypotenuse, cos = adjacent/hypotenuse, and tan = opposite/adjacent...know that for this problem tells you that cos = 5/13 and tan = 12/5 so thus sin = 12/13 (opposite = numerator of tan, hypotenuse = denominator of cos)
The way to solve this question is to essentially reverse the equation I used in the other answer.
I would solve this with some theoretical values. If you start with 3, how long would it take for it to triple, or reach 9.
the equation would look like 9 = 3(2)^t/6, note how the instead of 1/2 it is now 2 in the parenthesis, as it doubles every 6 hours rather than halves every amount of hours.
When placed into an algebra calculator, the answer should be about 9.5 hours
