So the equation to find the discriminant is $b^2-4ac$ , with a = x^2 coefficient, b = x coefficient, and c = constant. Using that formula, our equation is $(-5)^2-4*3*4$

Firstly, solve the exponent and multiplications: $25-48$
Next, do the subtraction, and your discriminant is -23.

Now because the discriminant is less than zero, there are no real solutions.

The coordinates for triangle LMN are given below. If Joel plans to transform LMN using the rule (x, y) = (-y, x), which is a tru

Mice21 [21]

Answer:

ok the answer should be A.

Step-by-step explanation:

you transform the coordinates from (x,y) to (-y,x)

this means to flip the coordinates like bring y up front and change its sign and take x to the initial y position.

for example if (-1,9) when you do the transformation you get (-9,-1). you take initial -1 to the right and bring 9 to left and change its sign.

when you are done you can see that the x axis coordinates are the same but the y axis coordinates are the direct opposite. this means that after the transformation the triangle would look like the mirror image of the original triangle.
