watching a television with a 13-inch screen to a television
with a similar 19-inch screen. If a boxcar
appeared 8 inches long on the 13-inch screen, how
long, to the nearest inch, will it appear on the 19-inch
screen?
The boxcar will appear 12 inches long on the 19-inch screen.
To find out how long the boxcar will appear on the 19-inch screen, we can set up a proportion using the relationship between the screen sizes and the length of the boxcar. Let's call the length of the boxcar on the 19-inch screen 'x'. So, we have the proportion:
13/8 = 19/x
Solving for 'x', we can cross multiply and divide:
x = (19 * 8)/13
Calculating this gives us 'x' to be approximately 11.7 inches. Rounding to the nearest inch, the boxcar will appear 12 inches long on the 19-inch screen.

Answer:
A
Step-by-step explanation:
Given
f(x) =
To evaluate f(a + 2), substitute x = a + 2 into f(x)
f(a + 2) = = → A
-4x+2y=2
Solve using algebraic methods.
