Which of the following expressions is equivalent to 5(2x + 1)-4 show your work to justify your response test at least one value of x to check your answer a. 10 x -3 b. 7 x -3 c. 10 x + 1 d. 7x + 1

Lets Simplify Step by Step:

5(2x + 1) - 4

Distribute:

(5)(2x) + (5)(1) + -4

10x + 5 + -4

Combine Like Terms:

10x + 5 + -4

(10x) + (5 + -4)

10x + 1

Hence, Letter Choice, (C); 10x + 1 ===> 5(2x + 1) - 4

CHECK:

5(2x + 1) - 4 > 10x + 1 ===> True for all x ===> Both Sides Equal.

Steps:

5(2x + 1 ) - 4 = 10x + 1

Expand:

5(2x + 1 ) - 4 > 10x + 1

10x + 1 > 10x + 1

Subtract 1 from both sides:

10x + 1 - 1 > 10x + 1 - 1

Simplify:

10x = 10x

Subtract 10x form both sides:

10x - 10x = 10x - 10x

Simplify:

0 = 0

Therefore, when checked, 5(2x + 1 ) - 4 ===> 10x + 1, Which makes Both Sides Equal; True for All " x "

Have a great day : )

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
