The point of interest is where the graphs cross.
(x, y) = (11, 5)
_____
Linear equations can be solved by any of a variety of methods. Using substitution for y, you have
.. 7x +3(27 -2x) = 92
.. x = 11 . . . . . . . . . . . . . collect terms, subtract 81
Then
.. y = 27 -2*11 = 5
(gof)(-3) means the composition of two functions at x = -3.
(gof)(-3) can also be expressed as g(f(-3))
So, first we find f(-3)
f(x) = x² + 5
f(-3) = 9 + 5 = 14
g(f(-3)) = g(14)
g(14) = (14+5)/14 = 19/14
Thus, option C gives the correct answer
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish
