Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2
vladimir2022 [97]

ANSWER


x=-0.62 or x=1.62




EXPLANATION


For -x^2+y=1



We make y the subject to obtain,



y=x^2+1


We can easily graph this function, because we just have to transform the graph of y=x^2 by shifting the intercept up to 1.



As for the straight line, -x+y=2,


We find the intercepts as follows,



When y=0,x=-2.


When x=0,y=2.


We plot the points (-2,0) and


(0,2).



We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be


x=-0.62 or x=1.62


See graph

Alexandra [31]

area of yard = 41 x 60 = 2460 square feet

walk is 4 feet wide

 41-4 =37, 60-4 = 56

37*56 = 2072

2460-2072 = 388

Is triangle AXY inscribed in circle A? <br> yes no
Ratling [72]

Answer:

Δ AXY  is not inscribed in circle with center A.

Step-by-step explanation:

Given: A circle with center A

To find: Is Δ AXY inscribed in circle or not

A figure 1 is inscribed in another figure 2 if all vertex of figure 1 is on the boundary of figure 2.

Here figure 1 is Δ AXY with vertices A , X and Y

And figure 2 is Circle.

Clearly from figure, Vertices A , X and Y are not on the arc/boundary of circle.

Therefore, Δ AXY  is not inscribed in circle with center A.
