Ty for your tips my score went up 50 points on math and got a 1250!

[@kyliechristina234]

Yay!

[@jksatori]

Also, the reason for when you put with Zero and it doesn't show the graph is because putting zero means we are asking for the roots but that equation has imaginary roots that's why without 0 it gets graphed, i hope it is understandable what i wrote

[@Methodtestprep]

You are correct! That's actually a really easy way of explaining what's going on!

It's not that desmos has some sort of initial distaste towards some of your equations, it's the fact that they are one variable equations without y values.

thank you!!!!!!

How can you solve the last question without a calculator?

[@Methodtestprep]

Both are set up as y = , so they must equal each other, so set them equal to each other, giving you 2x^2-21x+64=3x+a. Now get everything to one side and you get . Because they say these intersect in exactly one point, that's equivalent to saying that the of the quadratic formula is equal to 0. The discriminant is the part under the radical in the quadratic formula, b^2 - 4ac. (By the way, two solutions means discriminant is > 0, no solutions means discriminant is < 0). Now use the coefficients of this quadratic as our a, b, and c to plug into the discriminant, which we set equal to 0. a= = 2, b = -24, c = 64 - a. So b^2 - 4ac = 0 will become (-24)^2 - 4(2)(64 - a) = 0, which becomes 576 - 512 + 8a = 0, which becomes 64 + 8a = 0, or 8a = -64, so a = -8. But we need to find x, so we plug this back in for a to get 2x^2-24x+64-(-8)=0, or 2x^2-24x+64+8=0, or 2x^2-24x+72=0. Now divide all by 2 to get x^2-12x+36=0, which factors to (x-6)(x-6)=0, so x-6=0 and . Wow. That was long!!!!
