4x ²-3x+2=0

can you me solve this

x = (-3 ±√41)/8

Step-by-step explanation:

When you match your equation to the form ...

... ax² +bx +c = 0

you can see that ...

These are the values you use in the quadratic formua to find the solutions for x.

... x = (-b ±√(b²-4ac))/(2a) . . . . . . the quadratic formula

... x = (-(-3) ±√((-3)² -4(-4)(2)))/(2(-4)) . . . . fill in a, b, c

... x = (3 ±√(9+32))/(-8) . . . . simplify a bit

... x = (-3 ±√41)/8 . . . . . . put the minus sign in the numerator

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
