We can see that g(1) = f(4).
So g(x) = f(4*x)
k is 4
Maria will do more laps this year, assuming that last year they didn't do one or zero laps.
Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that

We have the a² and the b² in the equation
, and we <em>almost </em>have a 2ab in the equation
. To get that 2ab, we can simply double both sides of the first equation to get
. From there, we'll add the first two equations together, giving us the summed equation

And since
, we can equivalently say that

Answer: D. 2.8
Explanation:
7.7 + d = 10.5
Plug 2.8 as d in the equation
7.7 + 2.8 = 10.5
This is a true statement so D is the correct answer!
