The roots of a graph are also known as the x-intercepts. If you use a graphing tool to graph the given equation you will be able to see the x- intercepts. For the answer the question is asking what the x cordinates of the x intercepts are. I think the answer is (0,2,-2) but im not sure so you should check my work.

A.60 degrees <br> B.35 degrees<br> C.80 degrees <br> D.40 degrees
Romashka-Z-Leto [24]

Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.

Graph 4x2+4y2=64. What are the domain and range?
worty [1.4K]

ANSWER

EXPLANATION

The given equation is

4 {x}^{2}  + 4 {y}^{2} = 64

We divide through by 4 to obtain;

{x}^{2}  + {y}^{2} = 16

This can again be written as:

{x}^{2}  + {y}^{2} =  {4}^{2}

This is the equation of a circle centered at the origin with radius 4 units.

The graph is shown in the attachment.
