Answer:
The answer to your question is:
x 1 = -0.65
x2 = 7.65
Step-by-step explanation:
Equation -x² + 7x + 5 = 0
a = -1
b = 7
c = 5
Quadratic formula x = -b ±√(b² -4ac) / 2a
x = - 7 ± √(7² -4(-1)(5) / 2(-1)
x = -7 ± √(49 + 20) / -2
x = -7 ± √69 / -2
x = - 7 ± 8.3 / -2
x1 = -7 + 8.3 / -2 x2 = -7 -8.3 / -2
x 1 = -0.65 x2 = 7.65
The answer is b because 7 plus 2 equals 9 and a equals whole amount then his current amount is A-9
Technically it's 2x subtracted by 1 and 8 more than that so:
(2x-1)+8
Answer:
