Question:
Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?
Choose 1 answer:


C. None of the above
Answer:

Step-by-step explanation:
Given
Numbers: 1.7 and -1/2
Required
Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;

Then, we calculate the distance;
<em>In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;</em>
Hence,

Substitute
for Difference;

<em>Hence, the correct option is B</em>
Answer:
y = -3/4x - 2
Step-by-step explanation:
y = -3/4x + b
1 = (-3/4) × -4 + b
1 = 3 + b
-2 = b
b = -2
y = -3/4x -2
Answer: ...
Step-by-step explanation:
Answer:
1. x = 12
2. x = 5
Step-by-step explanation:
1. -222 = -2x - 12x - 54
-222 = -14x - 54
-168 = -14x
x = 12
2. 154 = 2x + 12x + 84
154 = 14x + 84
70 = 14x
x = 5
