Answer:
The horizontal line test may be used to determine whether a function is one-to-one.
The vertical line test may be used to determine whether a relation is a function.
Step-by-step explanation:
<span>The given equation: y = 3x -7 and y - 3x = 5
Before we answer, let’s solve the given equation:
=> y – 3x = -7
=> y – 3x = 5
=> Subtract both equation. Cross out y – 3x, thus the remaining would be
=> -7 and 5; in where -7 is not equals to 5
Thus the system of equations is inconsistent because an inconsistent system has
no solution.
And there is no solution found of the given equations.</span>
3x^2 + 9x + 6 = 0
3x^2 + 3x + 6x + 6 = 0
3x(x + 1) + 6(x + 1) = 0
(3x + 6)(x + 1) = 0
3x + 6 = 0 and x + 1 = 0
3x = -6 and x = -1
x = -2 and x = -1
Answer: it’s -1/4
