Answer:
a = 9
Step-by-step explanation:
expand (y - 3)(y² + 3y + 9)
= y³ + 3y² + 9y - 3y² - 9y - 27
compare the coefficients of like terms with
y³ + 3y² + ay - 3y² - ay - 27
ay = 9y and - ay = - 9y ⇒ a = 9
U should know 100 pennies make =1 $
50 nickels=1$
10 dimes=1$
make an equation
now i guess rest u can solve it
"The expression has a variable in the denominator of a fraction" is the statement among the following choices given in the question that <span>best demonstrates why the following is a non-example of a polynomial. The correct option among all the options that are given in the question is the fourth option or the last option.</span>
The rate of change is the slope.
f(x) is the same as y...
f(x) = 3x + 9.....y = 3x + 9....and in y = mx + b form, the rate of change(slope) can be found in the m position.
y = mx + b
y = 3x + 9....so the slope or rate of change is 3...not 9...so answer is false
