in general:
if delta>0 the equation has 2 solutions
if delta=0 the equation has 1 solution
if delta<0 the equation doesn't have real solutions
here :
delta=-4n
if n>0=> delta<0 => c) never
Answer:
The answer is 4
Step-by-step explanation:
Solve:
p = 1
q = 1
= (1+1)2 - (5-5)
= 2+2 -5 +5
= 4

Answer:
Step-by-step explanation:
Given the inequality
|x|> 1
The modulus of x shows that x can be both positive and negative value.
If x is positive:
x>1
1<x
If x is negative:
-x>1
Multiplying both sides of the inequality by minus will change the inequality sign
x < -1
Combining both inequalities:
1<x<-1

Answer:
1.88
Step-by-step explanation:
A farmer sells 9.4 kilograms of pears and apples
4/5 of the total weight is pears while the rest is apple
Let x represent the number of apples
9.4= 4/5 ×9.4 + x
9.4 = 0.8×9.4+x
9.4 = 7.52+ x
9.4-7.52= x
1.88= x
x= 1.88
