Jonathan must determine the solutions of the quadratic equation 0=4x^2+3x+8 which of the following is a solution to the equation.

option A

Step-by-step explanation:

Using quadratic formula:

We will have 2 solutions.

0=4x^2+3x+8     a=4   b=3   c=8

We have:

So

The solutions are not real numbers.

We know:

We can write:

so the option is A:

the answer is c. 23/3

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
