Find the discriminant of 3x^2-10x=-2
Oksanka [162]

Answer:

76

Step-by-step explanation:

given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0

then the discriminant is Δ = b² - 4ac

given 3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10 and c = 2

b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76

Marie has a small copy of rene magritte's famous painting, the schoolmaster. Her copy has dimensions 2 inches by 1.5 inches. The
prisoha [69]
First, lets convert our dimensions into cm. 

2*2.54 = 5.08 cm.
1.5*2.54 = 3.81 cm.

Now, lets multiply by for the get the dimensions of the original painting in inches. 

5.08*40 = 203.2 cm
3.81*40 = 152.4 cm

Finally, lets divide our new dimensions.

203.2/2.54 = 80 in.
152.4/2.54 =  60 in.

The dimensions of the original painting is 80 in. by 60 in.

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.
