A. They are both proportional because they have the same ratio.
b. The two graphs are the same because they have a constant rate of change (50), but they have different y-intercepts.
Since the quotient of the two decimal numbers is 1, that tells use that they are the same number.
Since the sum of the two numbers equals 1 and both numbers are the same, then the answer must be 1 divided by 2. or .5
the fractions would be 1/2 and 1/2
we have the function

we know that
The zero's of the function are the values of variable x when the value of the function is equal to zero
so
in the given function the zero's are

therefore
<u>the answer is</u>
