Answer:
Step-by-step explanation:
a = - 4
b = 10
c = - 8
The discriminate is
D = b^2 - 4ac
D = 10^2 - 4*(-4)(-8)
D = 100 - 128
D = - 28 which is not a nice number
Because the Discriminate has a minus result, there are no real zeros.

Answer:
Step-by-step explanation:
C. -11<x<-4
|-2x-15|<7 split into possible cases
- 2x - 15 < 7, - 2 x - 15 > 0
-(- 2x - 15 ) <7, -2x - 15 < 0 solve the inequalities
x>-11, x < -15/2
x< -4, x> -15/2 Find the intersections
[ -11, -15/2 ]
-15/2, -4] Find the union
[-11, -4 ] Simplify
-11<x<-4
Answer: x = 1
Step-by-step explanation:
2.8 + 2x = 0.6 x 8
2.8 x + 2x = 4.8
2x = 4.8 - 2.8 (subtract 2.8 on both sides)
2x = 2
x = 1 (divide 2 on both sides)
