How do you now if 94 is a prime number

2 answers:

94 is not a prime number. Because you have a "4" at the end of 94 that means that it is divisible by 2. 2 x 47 is 94. Because it has factors more than one and itself, it has to be a composite number

10n -11 =3 + 4n + 6n

10n - 10n -11 =3-3 + 4n + 6n

-11 - 3 = -10n + 4n + 6n

-14= -10n + 10n

-14 = n

Step-by-step explanation:

10n -11 =3 + 4n + 6n

10n - 10n -11 =3-3 + 4n + 6n

-11 - 3 = -10n + 4n + 6n

-14= -10n + 10n

-14 = n

Re-write the quadratic function below in Standard Form y=-5(x+1)²+7

Arturiano [62]

Answer:

y = - 5x² - 10x + 2

Step-by-step explanation:

y = - 5(x + 1)² + 7 ← expand (x + 1)² using FOIL

= - 5(x² + 2x + 1) + 7 ← distribute parenthesis by - 5

= - 5x² - 10x - 5 + 7 ← collect like terms

= -5x² - 10x + 2 ← in standard form
