Answer:

y = 20

Step-by-step explanation:

9 -  \sqrt{y - 4}  = 5

<h3>i) move 9 to the right-hand side and change its sign</h3>

-  \sqrt{y - 4}  = 5 - 9

<h3>ii) calculate the difference</h3>

-  \sqrt{  y - 4}  =  - 4

<h3>iii) change the signs on both sides of the equation</h3>

\sqrt{y - 4}  = 4

<h3>iv) square both sides of the equation</h3>

( \sqrt{y - 4} ) {}^{2}  = 4 {}^{2}

y - 4 = 4 {}^{2}

y - 4 = 16

<h3>v) move -4 to the right-hand side and change its sign</h3>

y = 16 + 4

<h3>vi) add the numbers</h3>

y = 20

I got 6 questions plz help PLEASE HELP ASAP I DONT UNDERSTAND
GaryK [48]

The answers to your questions are,

1. Point, Line, and Plane

2. Ray: A ray is like a line, but the line takes off in one direction to infinity while the other side is like a line segment. The end of the line is called the endpoint.

3. They are both containing geometry statements.

4.Say you have an angle of QPR. About 45 degrees.

Place the compass point on the angle's vertex.

Set the compass to ant convenient width.

Draw an arc across each leg.

Compass can be adjusted at this point if desired.

From where the arc crosses a leg, make an arc in the angle's interior.

Without changing the compass width, repeat for the other leg.

Draw a line from Q to where the arcs cross

Done! :)

5. A diameter of the circle is drawn.

A perpendicular bisector of the diameter is drawn using the method described in Perpendicular bisector of a segment. This is also a diameter of the circle.

The resulting four points on the circle are the vertices of the inscribed square.

6.  In a regular hexagon, the side length is equal to the distance from the center to a vertex. In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, equilateral triangles are also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
