1 answer:
Answer:
square feet
Step-by-step explanation:
We are given that
Side of square tile=
Total number of tiles used in rectangular floor=20
Area of square=
Area of square tile=square feet
Area of rectangular floor covered by square tiles =Area of 20 square tiles
Area of rectangular floor covered by square tiles= square feet
Area of rectangular floor covered by square tiles= square feet
Hence, the area of rectangular floor covered by square tiles= square feet

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.
