The answer
<span>to eliminate t from the parametric equations x=t^2+3 and y=4t
we have t²= x-3, and then t= sqrt(x-3), but we know that y=4t, which implies t=y/4. We only substitute the value of t by y/4, so </span>t= sqrt(x-3) wich is equivalent to y/4=sqrt(x-3), so at last y= 4 sqrt(x-3). t exactly eliminated.
so the true answer is
<span>D)She should first substitute y for t before solving.</span>

Arc MN is 100 degrees because it is the double of 50 degrees.
12x+4=100
12x-4=100-4
12x=96
x/12=96/12
x=8

40% in a fraction is 2/5 it is also 0.4 in a decimal if you're curious
Kilo is the unit prefix for multiplication by one thousand. Therefore, a kilogram, or kg, is equal to one thousand grams. To convert grams to kilograms, you simply have to multiply the number of kilograms to grams.
So, for example, if you had 16.24kg of a compound, it would equal:
