Subtract 5 to both sides so that the equation becomes -2x^2 + 6x - 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -6 ± √((6)^2 - 4(-2)(-1)) ] / ( 2(-2) )
x = [-6 ± √(36 - (8) ) ] / ( -4 )
x = [-6 ± √(28) ] / (-4)
x = [-6 ± 2*sqrt(7) ] / (-4 )
x =3/2 ± -sqrt(7)/ 2
The answers are 3/2 + sqrt(7)/2 and 3/2 - sqrt(7)/2.
Hamburgers/pickles
3/9 x/100 cross multiply to get 300=9xx
Now you have an algebraic equation.
divide 300 by 9, and you'll have your answer which is 100 pickles.
Answer:
The total change in value of her shares is $300
Step-by-step explanation:
Given that each share went up by $10 and she has 30 shares then the total change in the value of her shares is the product of the change in the price of each share and the total number of shares she has
= $10 * 30
= $300
