Answer:
x = 23; not extraneous
Step-by-step explanation:
A solution is extraneous if it does not satisfy the original equation. Extraneous solutions can sometimes be introduced in the process of solving radical and rational function equations.
<h3>Solution</h3>
Squaring both sides of the given equation, we get ...
√(3x +12) = 9
3x +12 = 81 . . . . . . square both sides
x +4 = 27 . . . . . . . divide by 3
x = 23 . . . . . . . . . . subtract 4
<h3>Check</h3>
There is only one solution, and it satisfies the equation:
√(3×23 +12) = √81 = 9
The solution x = 23 is not extraneous.

Step-by-step explanation:
Answer:
slope is 7
Step-by-step explanation:
the rate of change is the slope
in the general equation y = mx + b
x and y are point coordinates (x,y)
b is the y intercept
m is the slope
this is the rate at which the points are changing essentially
a larger slope will produce a steeper line
a negative slope will produce a line pointed downward
a smaller slope will produce a flatter line
