This is just a porportion. So if 250 meters is 1 meter than: 250/1
And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x
Set them equal to each other 250/1=212/x
Cross multiply: 212=250x
Divide to find x: 212/250=x
x=212/250
x=0.848
So the height of the model, to the nearest 10th would be 0.8 meters.

Answer:
y=-4x+1
Step-by-step explanation:
we know that parallel lines have equal slopes
first, we need to put 4x+y=4 into y=mx+b form
4x+y=4
-4x -4x
y=-4x+4
this means we have a slope of -4
we now know the new slope has to be -4
since we are given a point, we can put this into slope point form
the equation for this is y-y1=m(x-x1) with m posing as our slope
now we plug in
y--3=-4(x-1)
y+3=-4x+4
-3 -3
y=-4x+1
we now know the y-intercept is 1
The answer is <em>x = 3</em>, because x = 3 has an undefined slope (m = 0 or is imaginary), and it contains 3, 0 which makes 3, 0 a solution.
