One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
<span>The answer to this question is the attached image below: It is the given dominoes in each number that matches to the same number of dominoes that former options has to the latter choices. As shows the solution is given below as to clearly show the equation which is designated to the desired domino.</span>
The equation for the parabola would be:
I don't understand your question. can you make it clear
<span>11(23-x)
= 11(23) - 11x
= 253 - 11x</span>
