Does x=3 satisfy 2x-1=4? Explain your reasoning

Mathematics
1 answer:
lisabon 2012 [21]3 years ago
4 0

Answer:

No.

Step-by-step explanation:

Plug in 'x' for 3.

2(3)-1=4\\\\6-1=4\\\\\boxed{5\neq 4}

'x = 3' is not a solution because when plugged in the final product is a contradiction.

Hope this helps.

30 Points! Please help!<br><br> Is this a function? (-8,-16), (-2,-8), (-2,0), (6,4), (8,12)
levacccp [35]
No this is not a function because it is not one to one! Each x value needs to have only one output! The -2 values have two different outputs thus making it not a function.

Nada drives her car at an average speed of 60 miles per hour. She is planning a drive between 150 and 180 miles. Write and solve
tatuchka [14]

The inequality model that can be used to solve the number of hours it would take Nada to drive is 2.5 ≤ x ≤3.

<h3>What is the number of hours it would take Nada to drive?</h3>

Average speed is the total distance travelled per time.

Average speed = total distance / total time

Time = total distance / average speed.

Time if she drives 150 miles = 150 / 60 = 2.5 hours

Time if she drives 180 miles = 180 / 60 = hours

2.5 ≤ x ≤3.
