An equation in the form ax2+bx+c=0 is solved by the quadratic formula. The solution to the equation is shown below.x=−7±√ "572"

7nadin3 [17]

Answer:

B: a = 1, b= 7, c = -2

Explanation:

$\sf Quadratic \ Equation : \dfrac{-b\pm \sqrt{b^2 - 4ac} }{2a}$

Knowing This:

solve for b

-b = -7

b = 7

solve for a:

2a = 2

a = 1

solve c:

b² - 4ac = 57

7² - 4(1)(c) = 57

-4c = 57 - 49

-4c = 8

c = 8/-4 = -2

30 is 60%of what number?

Rom4ik [11]

Answer: 50

Step-by-step explanation:

Step 1: 60% = .60

Step 2: 30 = .60Y

Step 3: Divide both sides of the equation by .30 to isolate the variable Y.

30/.60 = .60/.60Y

50=Y

Therefore, 30 is 60% of 50.
