Answer:
Last option: Square both sides of the equation in step 1 to eliminate the square root.
Step-by-step explanation:
The error is in the process of subtracting 3 from both sides, since +3 is inside the root.
In order to be able to operate with the terms that are inside the root, we need to eliminate the root, and for that we need to square both sides of the equal sign.

Which ordered pair is a solution to the system of inequalities?
y > 3x
y <2 +5
Answers
The ordered pair which is the solution of the given inequalities is (A) (1,5).
What are inequalities?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. If a and b are equal, then an is greater than b.So, to find the correct values we need to use the hit-and-trial method:
Then, taking (1, 5):
y > 3x5 > 3(1)5 > 3 (Satisfied)Similarly,
5 ≤ x + 55 ≤ 1 + 55 ≤ 6 (Satisfied)So, option (A) (1, 5) is correct.
Therefore, the ordered pair which is the solution of the given inequalities is (A) (1, 5).

One radian is the measure of the central angle of a circle such that the length of the arc is equal to the radius of the circle.
A full revolution of a circle ( 360 ∘ ) equals 2 π r a di a n s. This means that 1 radian = 180 ∘ π .
The formula used to convert between radians and degrees is angle in degrees = angle in radians ⋅ 180∘ π .
The radian measure of an angle is the ratio of the length of the arc to the radius of the circle ( θ = sr ) . In other words, if s is the length of an arc of a circle, and r is the radius of the circle, then the central angle containing that arc measures radians.
Key Terms
arc: A continuous part of the circumference of a circle.
circumference: The length of a line that bounds a circle.
radian: The standard unit used to measure angles in mathematics. The measure of a central angle of a circle that intercepts an arc equal in length to the radius of that circle.
The x – and y -coordinates at a point on the unit circle given by an angle
t are defined by the functions x = cos t and y = sin t .
Although the tangent function is not indicated by the unit circle, we can apply the formula
tan t = sin t cos t to find the tangent of any angle identified.
Using the unit circle, we are able to apply trigonometric functions to any angle, including those greater than 90 ∘ .
The unit circle demonstrates the periodicity of trigonometric functions by showing that they result in a repeated set of values at regular intervals.
Key Terms
periodicity: The quality of a function with a repeated set of values at regular intervals.
unit circle: A circle centered at the origin with radius 1.
quadrants: The four quarters of a coordinate plane, formed by the x – and y -axes.
