Answer: D. x+2y+10
Trinomial refers to the fact that the polynomial has 3 pieces (x, 2y, and 10)
Constant term means there is a term with no variable (a number with no letters attached to it: In this example, that number is 10)
5x/7 - 5 = 50 is 4. x = 77
The answer is h to the power of 7 because you add the exponents
100, because, x^2 - 20x + 100 = ( x - 10 )^2;
Let x, represent the number of minutes and y represents the number of gallons of water in the tub, then the ordered pairs (2, 30) and (5, 12) satisfies the equation.
Therefore the equation is given by: (y - 30)/(x - 2) = (12 - 30)/(5 - 2)
(y - 30)/(x - 2) = -18/3 x = -6
y - 30 = -6(x - 2) = -6x + 12
y = -6x + 42
Required equation is y + 6x = 42.
