What could Eric have changed in his electromagnet that caused the decrease in magnetic force from point A to point B?
(You MUST give at least 3 possible reasons/changes in the electromagnet)

Explanation:

There is not context to know how the electromagnet is built and what the the points A, B, and C represent. Nevertheless, you can conclude from the graph that the force of the electromagnet decreased linearly from the situation A to the situation B.

The strength of the force from an electromagnet depends on:

How those factors can be modified to decrease the magnetic force from point A to point B:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
