Y = 0.5x^2 + 6x + 2      (adding 5 to both sides of the original equation)

Discriminant  b^2 - 4ac  =  6^2 - 4 * 0.5 * 2  =   36 -  4  = 32

The discriminant is positive and not a perfect square so the equation has 2 x intercepts.

The answer is actually 2 because you have 0.5x (I think that's what it's supposed to be) and 6x.

Which distance formula shows a direct variation? 1. D=50t 2. D=16t^2 3. D= r×t
VLD [36.1K]
The answer could be choice 1 or 3. 

With direct variation, we simply multiply one variable to get the other variable.

In #1, we are multiplying t by 50.

In #3, we are multiplying t by r.

In both cases, t is just be multiplied by a number.

Need help asap<br> solve for x using cross multiplication 5x over 7= 2x over 3
Alona [7]

Answer:

0.4

step-by-step explanation

5x times 3 = 7 times 2x-4

first, you divide both sides by 2x

2.5x times 3 = 7-4

then, divide both sides by three

2.5x = 1

lastly, divide both sides by 2.5

x = 0.4
