Simplify the expression –3(x + 3)2 – 3 + 3x. What is the simplified expression in standard form?

andrew11 [14]

For this case we must simplify the following expression:

$-3 (x + 3) ^ 2-3 + 3x$

We solve the parenthesis:

$-3 (x ^ 2 + 2 (x) (3) + 3 ^ 2) -3 + 3x =\\-3 (x ^ 2 + 6x + 9) -3 + 3x =$

We apply distributive property to the terms within parentheses:

$-3x ^ 2-18x-27-3 + 3x =$

We add similar terms:

$-3x ^ 2-18x + 3x-27-3 =\\-3x ^ 2-15x-30$

Answer:

$-3x ^ 2-15x-30$

What is the logarithmic function modeled by the following table? x f(x) 9 2 27 3 81 4

Nataly_w [17]

Answer:

Required logarithmic function is :

$f\left(x\right)=\log_3\left(x\right)$

Step-by-step explanation:

We have been fiven that table for the logarithmic function is:

x f(x)

9 2

27 3

81 4

which can be rewritten as:

x f(x)

3^2 2

3^3 3

3^4 4

Which are basically powers of 3

So we can use logarithmic function as

$\log_3\left(9\right)=\log_3\left(3^2\right)=2\log_3\left(3\right)=2(1)=2$

Hence required logarithmic function is :

$f\left(x\right)=\log_3\left(x\right)$

James has 6 stamps in his stamp collection. Roy has 12 stamps in his stamp collection. James adds 2 stamps to his stamp collecti

Yuliya22 [10]

For every one stamp James has Roy has twice as much. So the ratio would be 1/2. Hope this helped!
