Answer:
c
Step-by-step explanation:
C says that w must be greater than or equal to 452.2 and less than or equal to 455.0
One and a half = 1.5
Three and a half = 3.5
1.5 + 3.5 = 5.

Answer:
graph Y
Step-by-step explanation:
The inverse function can be found by solving ...
x = f(y)
x = -3y +3
x -3 = -3y . . . . . subtract 3; next, divide by -3
y = -1/3x +1 . . . . . matches graph Y
_____
<em>Additional comment</em>
Writing the original equation in standard form can help you see its intercepts.
3x +y = 3
3x = 3 ⇒ x = 1 . . . . x-intercept (at y=0)
y = 3 . . . . y-intercept (at x=0)
The inverse function has the x- and y-intercepts swapped, so you're looking for a line through (0, 1) and (3, 0). The lower left graph (Y) is that graph.
The answer is 90,000 because 10 to the power of 4 is 10,000 times 9 is 90,000
