The correct option is first option: x=t(y-4f)
Further explanation:
Given equation is:
In order to solve the equation for x, we have to isolate x on one side of the equation
Using Subtraction property of equality
Subtracting 4f from both sides
Multiplication property of equality
Multiplying both sides by t
Hence, the correct option is first option: x=t(y-4f)

Step-by-step explanation:
What is being asked here? Are they asking for the passing grade or the total with all the other 90 points added? I think it is A, 90%
Answer:
D
Step-by-step explanation:
Given
x² + 6x - 9 = 0 (add 9 to both sides )
x² + 6x = 9
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 9 + 9
(x + 3)² = 18 ( take the square root of both sides )
x + 3 = ± 
= ± 
= ± 3
Subtract 3 from both sides
x = - 3 ± 3 → D
