Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula? quadratic formula: x =

Step-by-step explanation:

Given : Equation

To find : The correct substitution of the the values a, b, and c from the equation into quadratic formula?

Solution :

The general form of the quadratic equation is

Where, a is the coefficient of

b is the coefficient of x

c is the constant term.

On comparing with  

a=-3 , b=-2 , c=6

The quadratic formula of the quadratic equation is given by,

Substituting the values,

So, The required formula which shows the correct substitution of the values.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
