Answer:
a = 1
Step-by-step explanation:
The important point here is that both lines are <em>horizontal reflections</em> of each other. If we treat the line x = a as a kind of "mirror" for these lines, every point at the same y value on each line is going to be an equal horizontal distance from that "mirror". If that's confusing, think about how, as you pull your hand away from a mirror, your hand's reflection seems to go deeper into it. As you bring it closer, your reflection gets closer too. And when you're touching the mirror, it seems like your hand and its reflection are touching!
We want to find that "touching" point for the two lines, the <em>intersection</em>, because it'll tell us exactly where our "mirror" - more commonly called the <em>axis of symmetry</em> - is. The point of intersection of any two lines is the point where their equations are exactly equal to each other.
Our equations are y = 3x - 5 and y = 1 - 3x, so setting those two equal to each other and solving for x:
This tells us that the two lines intersect at x = 1, which is exactly our axis of symmetry, so a = 1!
Answer:
The ratio is
Step-by-step explanation:
Remember that
1 ft=12 in
The Eiffel Tower is 984 feet
Convert to inches
984 ft=984*12=11,808 in
<em>Find the ratio of the height of the model to the height of the actual Eiffel Tower</em>
The height of the model is 24 in
The height of the actual Eiffel Tower is 11,808 in
the ratio is equal to
That means----> The height of the actual Eiffel Tower is 492 times greater than the height of the model
