Answer:

x ≤ 17

Step-by-step explanation:

This is the same as solving an equation, except instead of and equal sign it's an arrow.

We have to evaluate everything in the parenthesis first.

3x - 2 (x + 1) ≤ 15

3x - 2x - 2 ≤ 15

Next, we combine like terms - x's

3x - 2x - 2 ≤ 15

x - 2 ≤ 15

Combine like terms - constants (add 2 to both sides)

x - 2 ≤ 15

Please help I don’t understand this

Answer:

d. √(1/(x+1))

Step-by-step explanation:

Just as operations can be performed on numbers and variables, so can operations be performed on functions. Here, you're asked to simplify the ratio of two functions.

$\displaystyle\left(\frac{g}{f}\right)(x)=\frac{g(x)}{f(x)}=\frac{\sqrt{x-1}}{\sqrt{x^2-1}}=\sqrt{\frac{x-1}{x^2-1}}$

At this point, you're supposed to know the factoring of the difference of squares:

$\displaystyle=\sqrt{\frac{x-1}{(x-1)(x+1)}}=\boxed{\sqrt{\frac{1}{x+1}}}$

One number is one-third a second number. if the sum of the numbers is 48, find the numbers.

Gnoma [55]

First number assume A

Second number assume B

A= 1/3B ==> B= 3A

A+B = 48 ==> A+ 3A= 48

4A= 48 ==> A= 12

B= 3A= 36
