Answer:
m=-2
Step-by-step explanation:
As the product of the roots of a quadratic equation is c/a in ax^2+bx+c=0
here a=2, b=+8, c=-m^3
Given c/a=4
-m^3/2=4
-m^3=8
m^3= -8
m=-2.

Distance = SQRT((X2 -x1)^2 + (y2-y1)^2)
Distance = sqrt((2 - (-2)^2) + (-2 - 1)^2))
Distance = sqrt(4^2 + -3^2)
Distance = sqrt(16 + 9)
Distance = sqrt(25)
Distance = 5
Answer is D. (5)
4x+3y=19 and 6x-5y=-57
eliminate
multiply first equation by -6 and 2nd by 4
and add them
-24x-18y=-114
<u>24x-20y=-228 +</u>
0x-38y=-342
-38y=-342
divide both sides by -38
y=9
sub back
4x+3y=19
4x+3(9)=19
4x+27=19
minus 27 both sides
4x=-8
divide 4
x=-2
(x,y)
(-2,9)
