ok so to divide by a binomial you frist split the variable and the whole numbers down the middle, then you have t^2, t on one side and -13, -4 on the other
then you would divide both sides, dividing the numerator by the denominator, and that is your answer
Answer:

Step-by-step explanation:

Switch sides:

Subtract 17 from both sides:


The equation can be written in vertex form as
y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
-5 = a(-1+2)² -3
-2 = a . . . . . . . . . add 3 and simplify
The coefficient of the squared term is -2.
2y + 1/3 = 5
2y = -5 -1/3
2y = -16/3
Y = -8/3
Percentage change = difference/original x 100
(9.00-7.50)/7.50 x 100 = 2.50/7.50 x 100
= 1/3 x 100
= 33.3% increase
