Δ = b^2 - 4.a.c = 4 - 4.6.3 = -68< 0
rootΔ = root(-68)
no real solutions :) Cause -68 not positive.
Good Luck :)
Hey there!
10(5 - n) - 1 = 29
10(5) + 10(-n) - 1 = 29
50 - 10n - 1 = 29
49 - 10n = 29
-10n + 49 = 29
ADD 49 to BOTH SIDES
-10n + 49 - 49 = 29 - 49
WORK IT OUT or SIMPLIFY IT!
NEW EQUATION: -10n = -20
DIVIDE -10 to BOTH SIDES
-10n/-10 = -20/-10
WORK IT OUT or SIMPLIFY IT AS WELL!
n = 2
Therefore, your answer is: n = 2
Good luck on your assignment & enjoy your day!

Answer:
Irene had $3744 at first.
Step-by-step explanation:
Let Angie and Irene had the money initially = $a
At a shopping mall Angie spent money = $2595
Money left with Angie = $(a - 2595)
Similarly, Irene spent the money = $297
Money left with Irene = $(a - 297)
Money left with Irene was thrice as much as Angie,
(a - 297) = 3(a - 2595)
a - 297 = 3a - 7785
3a - a = 7785 - 297
2a = 7488
a = 
a = $3744
Therefore, Irene had $3744 at first.
Lana = x
Pam = 0.5x - 0.05
Cheryl = 0.5x - 0.05 + 3.10
Total 89$ = Lana + Pam + Cheryl
89 = x + 0.5x - 0.05 + 0.5x - 0.05 + 3.10
89 = 2x + 3
89 - 3 = 2x
86 = 2x
86/2 = x
43 = x
then Pam = 0.5(43) - 0.05
= 21.50 - 0.05
= 21.45
Cheryl = 21.45 + 3.10
= 24.55
The missing value is 6.
Use the slope formula and equal it to -3. Solve for x.
