The graph shows the functions f(x), p(x), and g(x):
Kruka [31]
Two functions have equal values where their graphs cross.

A) The solution to the pair of equations
.. y = p(x)
.. y = f(x)
will be where the graphs intersect, at (x, y) = (-3, -3).


B) We already know that (-3, -3) is one solution to y=f(x). The graph also appears to go through the point (0, 0).


C) p(x) = g(x) where their graphs cross, at x = -6. Both functions have the value 1 for that value of x.

A number decreased by 23 is 44. Find the number.
Hoochie [10]

Answer:

A

Step-by-step explanation:

The number is decreased by 23 which means 23 is subtracted from the number.

let the number be x, then

x - 23 = 44 ( add 23 to both sides )

x = 67

The number is 67
