If 2 pounds of bananas cost $1.89, what is the cost per pound? Show your work
OLEGan [10]
You can set up an expression where p = the pounds of bananas.
With that information, 2p =$1.89
To figure out the cost per pound, you want the cost of 1 p. Therefore, you divide both sides by 2. 
p = $1.89/2
p = $0.945
(since it is money you normally round to two decimal places so you would say $0.95 or 95 cents)

What values of x satisfy the equation 2x^2 -3x +4 =0
BaLLatris [955]

Answer:

(3 ± √23 * i) /4

Step-by-step explanation:

To solve this, we can apply the Quadratic Equation.

In an equation of form ax²+bx+c = 0, we can solve for x by applying the Quadratic Equation, or x = (-b ± √(b²-4ac))/(2a)

Matching up values, a is what's multiplied by x², b is what's multiplied by x, and c is the constant, so a = 2, b = -3, and c = 4

Plugging these values into our equation, we get

x = (-b ± √(b²-4ac))/(2a)

x = (-(-3) ± √(3²-4(2)(4)))/(2(2))

= (3 ± √(9-32))/4

= (3 ± √(-23))/4

= (3 ± √23 * i) /4
