3x-9=4x-9 Take the numbers together and the variables together so you’ll get -9+9=0 and 4x-3x =1x or x so x is equals to zero then substitute the zero on both of the equations to get Y= -9 So the answer it has one solution which is -9 at Y and so it’s considered 1 cause (0,9) and 0 is not a solution. Hope it helped:)
<h3>50 is the old value and 76 is the new value. In this case we have a positive change (increase) of 52 percent because the new value is greater than the old value.</h3>
Y = f(x) = -3x
y = -3x
y = (constant) x
y is proportional to x.<span>
Hence we can say Y is proportional to x , having (-3) as proportionality Constant. hope this helps</span>
