Solve the quadratic equation 3x^2 +x-5=0 give your answers to two decimal places

Explaination:

Quadratic Equation 3x²+x-5=0

The quadratic formula is the solution of the quadratic equation. There are various methods to solve the quadratic equation instead of using the quadratic formula, such as AC method (factoring), completing the square method, or graphing method.

Standard Quadratic equation is :

ax²+bx+c=0

The quadratic formula is :

x =

now put the values of a, b, c in this formula

a = 3, b= 1, c=-5

x =

or

x =

So final answer,

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
