Answer:
[-3 ±√(89)]/10
Step-by-step explanation:
<u>Points to remember</u>
Quadratic formula for finding the solution of a quadratic equation ax² + bx + c = 0 is given by,
x = [-b ± √(b² - 4ac)]/2a
It is given a quadratic equation,
5x² + 3x - 4
<u>To find the solution using formula</u>
Here a = 5, b = 3 and c = -4
x = [-b ± √(b² - 4ac)]/2a
= [-3 ± √((-3)² - 4*5*(-4))]/2*5
= [-3 ±√(9 +80)]/10
= [-3 ±√(89)]/10
The satire root of 5690 is 75.4320886626
Answer:
12000
Step-by-step explanation:
Jenkins had x dollars
He left 1/2 of that to his grandkids
He has x-1/2x = 1/x
He leaves 1/2 of that to his kids
1/2*1/2 x = 1/4x to his kids
His wife gets 1/6x
The rest is 1000
The total is
grand kids + kids + wife + 1000
1/2 x + 1/4x + 1/6x + 1000
He started with x
1/2 x + 1/4x + 1/6x + 1000 =x
Multiply each side by 12 to get rid of the fractions
12(1/2 x + 1/4x + 1/6x + 1000) =x*12
6x+3x +2x +12000= 12x
Combine like terms
11x +12000 = 12x
Subtract 11x from each side
11x-11x +12000 = 12x-11x
12000=x
Since he started with x, he left 12000 dollars
8(2)-y=4
16-y=4d
-1y/-1=-12/-1
y=12
(16,12)
