Solve the system of equations below by graphing. x^2-2x+y-3=0 x2+y=0 What is the solution rounded to the nearest hundredth? (–2.
Olin [163]

Answer:

(-1.5,-2.25)

Step-by-step explanation:

The first function is x^2-2x+y-3=0.


We make y the subject of this function to obtain,

y=3+2x-x^2.

This is graph will open downwards because a=-1\:.


At  y-intercept of this graph, x=0.


\Rightarrow y=3+2(0)-(0)^2


\Rightarrow y=3


The y-intercept is (0,3).


At x-intercept y=0.


0=3+2x-x^2


0=(x+1)(x-3)


\Rightarrow x=-1,x=3.


The x-intercepts are,

(-1,0),(3,0)

Also the vertex form of the function is,

y=-(x-1)^2+4.


Therefore the vertex of the parabola is (1,4).


We plot all the points obtained and draw a smooth curve to obtain the curve as show in the diagram.


The second function is

x^2+y=0


\Rightarrow y=-x^2


This is the graph of the basic quadratic function y=x^2 that has been turned upside down.

This graph also has the vertex,y-intercept and x-intercept all at (0,0).


We now graph this too on the same graph sheet as the first one to obtain the blue graph as shown in the diagram.


These two graphs intersect at the point, (-1.5,-2.25).


Therefore the correct answer is B

Mr. Hann is trying to decide how many new copies of a book to order for his students. Each book weighs 6ounces
Nina [5.8K]

Answer:

I’m afraid I can’t help you. The question makes no sense because the question doesn’t explain how many students there are. It just gives the weight of the books which I assume is useless
