Write a word phrase that can be represented by b – 6.
a. the difference of 6 and b

b. the quotient of a number b and 6

c. 6 more than a number b

d. 6 less than a number b

 The correct option is

(D) 6 less than a number b.

Step-by-step explanation:  We are given to write a word phrase that can be represented by the following expression :

"b - 6".

Since we are subtracting 6 from a number b, so the resulting number will be 6 less than b.

Thus, the required word phrase foe the given expression is

"6 less than a number b".

Option (D) is CORRECT.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
