The ph scale measures how acidic or basic a substance is. bleach is said to have a ph of less than 14 and greater than 11. model the normal range of ph values of bleach, using a compound inequality. 11 > x > 14 11 < x < 14 11 ≤ x ≤ 14 11 ≥ x ≥ 14

The answer to your question is:     11 < pH < 14

Step-by-step explanation:

Data

Bleach have a pH  less than 14 and greater than 11.

We have to use these symbols:

                                                     <  greater than       >  less than

and pH will be  in the middle

                                          11 < pH < 14

This inequality means the Bleach has a pH between 11 and 14

what is the question?

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
