I do not have an answer but you could always take an explanations how to do it easier. Hope it helps :)
Step-by-step explanation:
Example: solve √(2x+9) − 5 = 0
isolate the square root:
√(2x+9) = 5
square both sides:
2x+9 = 25
Now it should be easier to solve!
Move 9 to right:
2x = 25 − 9 = 16
Divide by 2:
x = 16/2 = 8
Answer:
x = 8
Check: √(2·8+9) − 5 = √(25) − 5 = 5 − 5 = 0
The answer is choice D) 4
(x/4) times 4 = x
You can think of it as
(1/4) times 4 = 1
The variation equation when y varies directly as the square of x is y = kx².
The value of y when x = 30 is 900k.
<h3 /><h3>Definition and types of variation:</h3>
Variation establish relationship between variable. Types of variation includes
- Direct variation
- Inverse variation
- Joint variation
- Combined variation
y varies directly as the square of x , Therefore,
where
k = constant of proportionality
Solve for y when x = 30.
Therefore,
y = kx²
y = 30²k
y = 900k
