Why is it important to check all solutions to radical equations?

2 answers:

When a power is taken on both sides of an equation, the resulting solutions might not check in the original radical equation. These are called extraneous solutions. You must check solutions by substituting in the values into the original equation and verifying that it produces a true statement.

Hello.

The solutions found to radical equations are not necessarily viable. They sometimes result in inequalities, and have to be checked.

Hope I helped.

CAN SOMEONE HELP ME PLEASE ILL GIVE BRAINLEST..I need step to step equation thanks

Answer:

The required co-ordinate is (-2, -5).

Step-by-step explanation:

For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: $R_{y = k} = (x, 2k - y)$ .

Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:

$R_{y = 1} (-2, 7) = (-2, 2(1) - 7)$

= (-2, -5)

The reflected point is (-2, -5).

What is the correct way to write a mathematical problem?

Zina [86]

Answer:

Label your answer appropriately; if the question asks for measured units, make sure to put appropriate units on the answer. If the question is a word problem, the answer should be in words. In general, write your homework as though you're trying to convince someone that you know what you're talking about.
