Question:
The relationship between t and r is expressed by the equation 2t+3r+6 = 0. If r increases by 4, which of the following statements about t must be true?
Answer:
The value of t is reduced by 6 when the value of r is increased by 4
Step-by-step explanation:
Given
Required
What happens when r is increased by 4
<em>-------- Equation 1</em>
Subtract 2t from both sides
--- <em>Equation 2</em>
When r is increased by 4, equation 1 becomes
Note that the increment of r also affects the value of t; hence, the new value of t is represented by T
Open bracket
Rearrange
<em>Substitutr -2t for 3r + 6 [From equation 2]</em>
Make T the subject of formula
Divide both sides by 2
This means that the value of t is reduced by 6 when the value of r is increased by 4
