Answer:
No Real Solutions
Step-by-step explanation:
So we have:
First, determine the domain restrictions. The expression under the radical cannot be less than 0. Therefore:
Therefore, our final answers must be greater than or equal to 3:
Now, going back to the original equation, subtract x from both sides:
Now, square both sides:
Distribute:
Subtract 4x and add 12 to both sides:
This isn't factor-able. Let's use the quadratic formula. a is 1, b is -4 and c is 12:
Substitute:
Simplify the radical:
The number under the radical is negative. In other words, there are no real solutions.
Answer:
b
Step-by-step explanation:
The answer would be 6 the easy way is to divide 48 by 8
The solutions of the equation 3x - y = 1 are (-2,-7),(-1,-4) and (3,8) thus option (A),(B) and (D) are correct.
<h3>What is the equation?</h3>
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given equation,
3x - y = 1
Substitute, x = -2
3(-2) - y = 1
y = -7 thus (-2,-7) satisfied.
Similarly (-1,-4) and (3,8) are also satisfied.
Hence "The solutions of the equation 3x - y = 1 are (-2,-7),(-1,-4) and (3,8)".
