Answer:

The correct answer is C. y = 3/4x - 12

Step-by-step explanation:

In order to find this, we must first note that the slope will be 3/4. We can tell this because parallel lines have the same slope. Next, we use that along with the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -18 = 3/4(x - -8)

y + 18 = 3/4 (x + 8)

y + 18 = 3/4x + 6

y = 3/4x - 12

From an absolute value inequality, we have that:

The minimum diameter is 6.46 mm.
The maximum diameter is 6.54 mm.

The absolute value measures the <u>distance of a point or a function to the origin</u>.

One example of inequality is:

$|f(x)| \leq a$

Which has solution:

$-a \leq f(x) \leq a$

In this problem:

Bolts with a diameter of 6.5 mm, with a tolerance of 0.04 mm, thus the <u>absolute value of the difference of the diameter D and 6.5 has to be of at most 0.04</u>, that is:

$|D - 6.5| \leq 0.04$
