The denominator of a rational number is greater than the numerator by 6 if the numerator and denominator are both increased by 2
DerKrebs [107]

Answer:

7/13

Step-by-step explanation:

Let's call x= numerator

We know that :

Denominator= x+6

And

(numerator +2)/(denominator +2) = 3/5

So

(x+2)/(x+6+2)=3/5

(x+2)/(x+8)=3/5

(x+2)*5=(x+8)*3

5x+10=3x+24

2x=14

x=7

In the end

Numerator= x =7

Denominator=x+6 = 13

So the original number is 7/13

I hope this helps, have a beautiful day

Given the functions f(x) = x2 + 6x − 1, g(x) = –x2 + 2, and h(x) = 2x2 − 4x + 3, rank them from least to greatest based on their
nevsk [136]
Axis of symmetry = x = -b/2a
where y = ax² + bx + c

f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3

g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0

h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1

least :       f(x) = x² + 6x - 1    ; axis of symmetry is -3
middle :    g(x) = -x² + 2         ; axis of symmetry is 0
greatest :  h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
