4(×+2)=
3 (a+2)=
2 (×+3)=

Answers

Answer 1

Answer:

Answer:

4(x+2) = 4*x + 4*2 = 4x+8

3(a+2) = 3*a + 3*2 = 3a + 6

2(x+3) = 2*x + 2*3 = 2x +6

Hope this help you :3

Answer 2

Answer:

Step-by-step explanation:

Use the distributive property a(b + c) = ab + ac

4(x + 2) = (4)(x) + (4)(2) = 4x + 8

3(a + 2) = (3)(a) + (3)(2) = 3a + 6

2(x + 3) = (2)(x) + (2)(3) = 2x + 6

Answers

Hey there! :) So first of all, I got 31.67 per second. The way I got my answer is first, I knew that 1 KM is 1000 Meters. So now, I multiplied 114 x 1000 which equals 114,000 Meters. Then, I figured out that 1 Hour has 3600 Seconds. Then I did 114,000 ÷ 3,600 and got 31.67 Seconds. And that is how I got the answer!

Hope it helps and it's the right answer & it's understandable! :D

Consider the following function.f(x) = √x - 2
Which of the following graphs corresponds to the given function?

Answers

Answer:

Graph Z

Step-by-step explanation:

The radical parent function is

$g(x)=√(x)$

The given function is

$f(x)=√(x-2)$

$f(x)=g(x-2)$ .... (1)

The translation is defined as

$f(x)=g(x+a)$ .... (2)

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

From (1) and (2) we get

$a=-2$

The value of a is negative so the graph of parent function shifts 2 units right.

Therefore, the graph Z represents the given function.

The letter z is the correct answer
