Answer:

-27 & -33 or 27 & 33

Step-by-step explanation:

Let the numbers are 9x and 11x.

<u>Their difference is 6:</u>

1. 9x - 11x = 6 ⇒ -2x = 6 ⇒ x = -3

The numbers are -27 and -33

2. 11x - 9x = 6 ⇒ 2x = 6 ⇒ x = 3

The numbers are 27 and 33

-0.113 blank =0.452x + 0.452

nataly862011 [7]

Answer:

a=-4

b=-4

Step-by-step explanation:

-0.113 blank =0.452x + 0.452

-0.113(a+bx) =0.452x + 0.452

-0.113a-0.113bx =0.452x + 0.452

so we have

-0.113a=0.452

a=-0.4520/0.113= -4

-0.113bx =0.452x

b=-0.452/0.113= -4

Identify all factors of the expression 〖4x〗^2+17x-15.

Basile [38]

The factors of given expression are: -5 and 3/4

Step-by-step explanation:

Given equation is:

$4x^2+17x-15$

Making pairs for the mid-term 17x by factoring the product of co-efficient of 4x^2 and 15

$4x^2+20x-3x-15$

$= 4x(x+5) - 3(x+5)$

$=(4x-3)(x+5)$

Now

$4x-3 = 0\\4x = 3\\x = \frac{3}{4}$

$x+5 = 0\\x = -5$

Hence,

The factors of given expression are: -5 and 3/4
