Answer:
y = -3x^2 -9x +30
Step-by-step explanation:
When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...
f(x) = (x +5)(x -2)
At the point x=3, the value of this product is ...
f(3) = (3 +5)(3 -2) = (8)(1) = 8
In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...
y = -3(x +5)(x -2)
y = -3x^2 -9x +30 . . . . . standard form
Answer:
Find the LCD (least common denominator)
{5}/{6} and {1}/{4}
it would be 12 (6x2=12 and 4x3=12)
so you multiply {5}/{6} by 2 and get {10}/{12}
then multiply {1}/{4} by 3 and get {3}/{12}
you get 3 WHOLE servings from {5}/{6} cups of icecream
