You can fill the second in in the first to get an equation with only b:
(b-2) - 3b = 22 =>
-4b-2 = 22 =>
-4b = 24
b = -6
a = -6-2 = -8
So (-8,-6) is the answer.
Step-by-step explanation:
15 : 25 : 40
So first we will divide it by 5
3 : 5 : 8
We cannot further divide it so it is the simplest form
3/4=0.75
0.75×500=375
375 of the 500 seats are filled
The function g(x) has vertex (0,2) and the function of the graph has vertes (-2,0), so this latter is the function f(x).
Now analyze the statements.
<span>Neither function is an even function ---> FALSE because the fact that the function g(x) has vertex (0,2) means that the symmetry axis of the parabole is the y-axis, so you know that g(x) = g(-x) which is the definition of an even function.
Only the function g(x) is an even function ---> TRUE: I already explained you why you can tell that g(x) is even. Now you just mut observe the graph of f(x) to realize that f(x) is not equal to f(-x) which means that it is not even.
Both functions are even functions ---> FALSE as we stated above f(x0 is not even.
Only the function f(x) is an even function ---> FALSE as we stated above.</span>
