Well, we know that y=1/2x+5 from the first equation. if we substitute that into the second equation, it becomes 2x + 1/2x +5 =1. solve for x. 2x+1/2x= -4, 2 1/2x=-4, x=-1.6. plug that in to one of the equations. 2(-1.6)+y=1, -3.2+y=1, y=-2.2. the solution is (-1.6, -2.2)

A model of the Eiffel Tower is 41 centimeters tall. If the scale model is 1 cm/24 feet of the real Eiffel Tower, how tall is the

In-s [12.5K]

Data:

Model: 41cm

Scale: 1cm/24feet

To convert the measure of the model to the real Tower you use the scale factor

The scale factor is 24ft/cm

To know the height of the Eiffel Tower you multiply the height in the model for the scale factor:

$41\operatorname{cm}\cdot24\frac{ft}{\operatorname{cm}}=984ft$ Then so, the height of the Eiffel Tower is 984ft
