For what value of x does 3 Superscript 2 x Baseline = 9 Superscript 3 x minus 4?
2 answers:
Answer:
b. 2
Step-by-step explanation:
=
------------------------------------(1)
To solve the equation above, we will follow the steps below;
9 = 3²
Will replace 9 = 3² in equation (1)
=
open the bracket
=
The 3 on the left-hand side will cancel-out the 3 on the right-hand side of the equation. Thus our equation becomes;
2x = 6x - 8
subtract 6x from both-side of the equation
2x - 6x = -8
-4x = -8
Divide both-side of the equation by -4
=
(On the left-hand side of the equation, -4 will cancel-out -4 while on the right-hand side of the equation -8 will be divided by -4)
x = 2

Answer:
The constant of variation is $1.50
Step-by-step explanation:
Given
Point 1 (1,2)
Point 2 (5,8)
Required
Constant of Variation
Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.
Having said that,
the constant variation can be solved by calculating the gradient of the graph;
The gradient is often represented by m and is calculated as thus
Where
By substituting values for x1,x2,y1 and y2; the gradient becomes
Hence, the constant of variation is $1.50
