It's true. They're connected, have a mutual relationship.

Need help with these questions!!! please explain bc I don't really get it!

Answer:

1. b. 2. a. 3. a.

Step-by-step explanation:

1. (f + g)x = f(x) + g(x)

= x^2 + 2x + 4

(f + g)(-1) = (f + g)(x) where x = 1 so it is

(-1)^2 + 2(-1) + 4

= 1 - 2 + 4

= 3.

2. We find (f o g)(x) by replacing the x in f(x) by g(x):

= √(x + 1) and

(f o g)(3) = √(3 + 1)

= √4

= 2.

3. (f/g) c = f(x) / g(x)

= (x - 3)/(x + 1)

The domain is the values of x which give real values of (f/g).

x cannot be - 1 because the denominator x + 1 = -1+1 = 0 and dividing by zero is undefined. So x can be all real values of x except x = -1.

The domain is (-∞, -1) U (-1, ∞)

Answer:

Associative property

Step-by-step explanation:

<u>The given property is:</u>

A + (B + C) = (A + B) + C

which is called "associative property of addition".

Hence, this property is used in the given expression which is "rearranging the parenthesis does not affect the result."

$\rule[225]{225}{2}$

Hope this helped!

Look at the rectangle and the square:

OlgaM077 [116]

Answer:

Sam is incorrect

Step-by-step explanation:

We can calculate the lengths of the diagonals using Pythagoras' identity.

The diagonals divide the rectangle and square into 2 right triangles.

Consider Δ SRQ from the rectangle

SQ² = SR² + RQ² = 12² + 6² = 144 + 36 = 180 ( take square root of both sides )

SQ = $\sqrt{180}$ ≈ 13.4 in ( to 1 dec. place )

Consider Δ ONM from the square

OM² = ON² + NM² = 6² + 6² = 36 + 36 = 72 ( take square root of both sides )

OM = $\sqrt{72}$ ≈ 8.5 in ( to 1 dec. place )

Now 2 × OM = 2 × 8.5 = 17 ≠ 13.4

Then diagonal OM is not twice the length of diagonal SQ
