Please help I don’t know this and I need help really really bad

Alex_Xolod [135]

Answer:

A, B, and C

Step-by-step explanation:

If you want to keep a shape congruent, you would only want to change the positioning of said shape.

Dilation is when you change the size of said shape, so it wouldn't work

Reflections are only reflecting a shape across a certain plane

Rotations are only rotating a shape around a point

Translations are literally just moving a shape

Therefore, the answers without dilation would be correct, so A, B, and C

Just need to solve number 8 with quadratic formula

choli [55]

$ax^2+bx+c=0\\\\x_1=\dfrac{-b-\sqrt{b^2-4ac}}{2a}\\\\x_2=\dfrac{-b+\sqrt{b^2-4ac}}{2a}$

$2x^2=8x-7\ \ \ \ |-8x\\\\2x^2-8x=-7\ \ \ |+7\\\\2x^2-8x+7=0\\\\a=2;\ b=-8;\ c=7\\\\b^2-4ac=(-8)^2-4\cdot2\cdot7=64-56=8\\\\\sqrt{b^2-4ac}=\sqrt8=\sqrt{4\cdot2}=2\sqrt2$
$x_1=\dfrac{-(-8)-2\sqrt2}{2\cdot2}=\dfrac{4-\sqrt2}{2}\\\\x_2=\dfrac{-(-8)+2\sqrt2}{2\cdot2}=\dfrac{4+\sqrt2}{2}$
