Step-by-step explanation:
-2.2 x (-2) / (- 1/4) x 5 PEMDAS
4.4 / -1.25
-3.52
Answer:
30 and -3
Step-by-step explanation:
30 x -3=-90
30-3=27
They are all -5 bigger than each other the rule is y = x - -5
Answer:
Step-by-step explanation:
y = -3x² + 24x - 50
factor out leading coefficient
y = -3(x² - 8x) - 50
complete the square
coefficient of the x term: -8
divide it in half: -4
square it: (-4)² = 4²
use 4² to complete the square and keep the equation balanced:
y = -3(x² - 8x + 4²) + 3(4²) - 50
y = -3(x-4)² - 2
