Answer:
what one
Step-by-step explanation:
if it is the left one it is -7(2x)+-7(7)+10x=-4x
Answer: A
Step-by-step explanation: A function means that your x can only have one y but your y can have multiple x's.
To make 5.6e12 standard you simply move the decimal place right 12 times
5,600,000,000,000
5 Trillion 600 billion
Answer:we know that all 3 sides are equal
so if side =a
then perimeter =3a
therefore
3a=6n-15
a=6n-15/3
a=2n-5
Answer:
A
Step-by-step explanation:
Given the zeros are x = - 1 and x = 3 then the factors are
(x + 1) and (x - 3) and the parabola is the product of the factors, that is
y = a(x + 1)(x - 3) ← where a is a multiplier
To find a substitute (0, - 9) into the equation
- 9 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )
3 = a, thus
y = 3(x + 1)(x - 3) ← expand the factors using FOIL
= 3(x² - 2x - 3) ← distribute by 3
= 3x² - 6x - 9 → A
