Best ResponseYou've already chosen the best response.0evidently the line through (7,7) meets y = x at (7,7) !!

Best ResponseYou've already chosen the best response.0#15) Find the intersection of the line through points (7,7) and (4,2) with the line y=x. The point of intersection is (A,B) where A=___ B=___

Best ResponseYou've already chosen the best response.0\[x^23\] intersect the x axis at \[\sqrt{3}\] and \[\sqrt{3}\] and the distance between these to points is \[2\sqrt{3}\]

Best ResponseYou've already chosen the best response.0#15 not to be snarky, but it is asking who is buried in grant's tomb. if it goes through (7,7) that is where y = x

Best ResponseYou've already chosen the best response.0for #20 you have to decide which rule to use. since \[1\leq 2\] you know \[f(1)=2\times 1=2\]

Best ResponseYou've already chosen the best response.0since \[x>2\] =you use \[f(3)=6\times 3^2+3+4\]

Best ResponseYou've already chosen the best response.0and since \[2 \leq 2\] is true you use \[f(2)=2\times 2=4\]

Best ResponseYou've already chosen the best response.0yeah, i knew that i had to do that for 20 but i got the wrong answer for some reason... for 18, i dont know why the answer is not 3 or 4.

anonymous

Best ResponseYou've already chosen the best response.0because you are asked for the distance between \[(\sqrt{3},0)\] and \[(\sqrt{3},0)\] and that is \[2\sqrt{3}\]

Best ResponseYou've already chosen the best response.0o sorry, didnt see u solved #18 too cause u didnt put the # in front of it.

Best ResponseYou've already chosen the best response.0and for #20 i got 2, 61, and 30 but those are wrong... why?

Best ResponseYou've already chosen the best response.0Do you know how to find the points where the parabola crosses the x axis?

Best ResponseYou've already chosen the best response.0If a point is on the x axis, the y value is 0 so set y = to 0 and solve

Best ResponseYou've already chosen the best response.0so i would get plus minus radical 3

Mertsj

Best ResponseYou've already chosen the best response.0Yes. So the parabola crosses the x axis at (sqrt3,0) and (sqrt3,0)

Mertsj

Best ResponseYou've already chosen the best response.0But the question doesn't ask for the two points. It asks for the distance between the points. Do you know how to find the distance between two points?

Best ResponseYou've already chosen the best response.0\[d=\sqrt{(x _{2}x _{1})^{2}+(y _{2}y _{1})^{2}}\]
