Answer:
D)The equation is f(x)=3x^2−9x+3, and the parabola opens upward.
Answer:
r = P -t -s
Step-by-step explanation:
This is a one-step linear equation in r. Subtract the terms that don't contain r:
P = r + t + s . . . . . . . . . . given
The terms on the right that don't include r are (t+s). We want to subtract that to get r by itself.
P -(t+s) = r +(t+s) -(t+s) . . . subtract (t+s)
P -t -s = r . . . . . . . . . . . . . . simplify
r = P - t - s
27 cubic inches
Because you multiply 3x3x3=27
If we want to write the function in vertex form:
f ( x) = 6 x² + 5 - 42 x = 6 x² - 42 x + 5 = 6 ( x² - 7 x ) + 5 ...
First step is: C ) write the function in standard form ( y = ax² + b x + c )
