The solution of two equations/lines is their intersect point.
Therefore, there can only be one intersection point/solution, because these lines are neither parallel or identical.
In the graph you can see that they intersect at (x,y)=(2,3) which is your solution and option b or d as one of them seems to be mistyped :)
@question2
y=kx+b
both your equations share the same k=-2:
y=-2x+3
y=-2x-1
therefore these lines are parallel and don't have any intersection as they are always at different y values (the b)
Testing for y-symmetry let's make r = 5 cos 3θ and set <span>θ=π−θ</span> so<span><span><span>r=5cos3θ</span><span>θ=(π−θ)</span><span>r=5cos(3(π−θ))⟹r=5cos(3π−3θ)</span></span></span>
The first answer would be A because the volume is l*w*h so you would multiply 24 by 10 by 12 which gives you 2880 ft^3
I don't know how to do the second question. I am sorry!
AED is adjacent to 44 and these two angles are supplementary, meaning they sum to 180 so...
AED=180-44=136°
It’s D because it is already simplified but C you can factor out the x so it can be simplified so D is the answer
