Answer:

|x-65|\leq 10

Step-by-step explanation:

It is given that the shortest person in a class is 55 inches tall and tallest person in that class is 75 inches tall.

Let x represent the heights.

Minimum value of x = 55

Maximum value of x = 75

The midpoint of maximum and minimum value is

Midpoint =\frac{Maximum+Minimum}{2}=\frac{75+55}{2}\Rightarrow \frac{130}{2}=65

Difference between extreme points and midpoint is

Difference =\frac{Maximum-Minimum}{2}=\frac{75-55}{2}\Rightarrow \frac{20}{2}=10

The absolute value equation is

| x - Midpoint | \leq Difference

| x -65 | \leq 10

Therefore the required absolute value equation that represents the minimum and maximum heights is |x-65| ≤ 10.

What is the slope of the line whose equation is 2x+3y = -12?
luda_lava [24]

Answer:

slope = - \frac{2}{3}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 3y = - 12 ( subtract 2x from both sides )

3y = - 2x - 12 ( divide all terms by 3 )

y = - \frac{2}{3} x - 4 ← in slope- intercept form

with slope m = - \frac{2}{3}
