Answer:
<h2>For the first triangle, <u>x equals 22cm.</u></h2>
Here's how:-
x is the altitude or height of the triangle. To find it, we can use the Pythagoras theorem:-

The base is 120cm and the hypotenuse is 122cm
Putting this in the equation, we get:-



= 484
altitude = 
<h3>altitude = 22cm</h3><h2><u>So, x = 22cm</u></h2>
So you can use
$21.95 + $.19x = $18.95 + $.21x
Anything withdrawn you subtract. Then, you know the total and you know what you had. Subtract total from what you had and you will see the change.
1735.97-100=1635.97
1668.71-1635.97=32.74
I think that the correct function in your question should be y = 60x⁻¹ + 0.625x.
With that said, the answer is A. <span>0 < x < ∞
By the process of trial and error of the choices, we can see that this choice satisfies the equation. Take note that y models moose population, so y should always be positive. </span>
