A student must find the slope of a line that passes through the points (2, 2) and (-1,3). Which of the statements below best applies to the sample mathematical work?
which gives a
V-
-2-2
Given the points above, I plug these values into the formula which yields the expression
*27*]
3-2
slope of -3.
A. the formula for the slope of the line is incorrect
B. the student failed to plug in the proper values into the slope formula
C. the numeric calculation to find the slope is incorrect
D. the mathematical work shown is correct

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
