siniylev [52]3 years ago
5 0

Answer:

Step-by-step explanation:

y=-3x²-4x+7...(*)

3x+2y=18...(**)

use (*) put the value of y in (**) :

3x +2(-3x²-4x+7)=18

3x-6x²-8x +14 -18 = 0

-6x²-5x- 4 = 0

6x²+5x+4 = 0

delta = b² - 4ac     a = 6   b=5    c =4

delta = 5² - 4(6)(4)= 25 -96= -71 negatif

so no reals solution

J(–6, 2) and K(3, 2) are the endpoints of the base of an isosceles triangle. Give the x-coordinate of the third vertex.
Korvikt [17]

Answer:

Step-by-step explanation:

If you plot J and K in a coordinate plane, you see that the line formed is a perfectly horizontal line through y = 2.  In order for this triangle to be an isosceles, the third x-coordinate would have to be located midway through the x-coordinates of the base.  The midpoint between the x-coordinates is found by adding the 2 x-coordinates and dividing the sum by 2.  -6+\3 = -3 and -3/2 = -3/2.  So the x-coordinate is -3.2 or -1.5
