Answer:

Step-by-step explanation:

-9 + x = -4

( move +x to right and -4 to left)

-9 +4= -x

[sign changes when number is moved]

-5= -x

[negative signs cancel out each other/ divide both sides by negative sign]

Will give BRAINLIEST!! I REALLY NEED HELP..What is -1/2(-3y+10) as a equivalent expression? pls help me
irina [24]
Any expression has many equivalents. For something like this, it is often convenient just to make use of the distributive property.

= (-1/2)*(-3y) +(-1/2)*(10)
= (3/2)y -5

Another equivalent has a common denominator
= (3y -10)/2

Which shows one way to determine the factors of 12x3 – 2x2 18x – 3 by grouping?.
Ksenya-84 [330]

The equation which shows the one way to determine the factors of provided equation by grouping is,

2x^2(6x-1)+3(6x-1)

<h3>What is a factor of polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

Factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

The provided polynomial equation is,

12x^3 - 2x^2 +18x - 3

To factorize the above polynomial equation, make the groups, by taking out the greatest common factor.

12x^3 - 2x^2 +18x - 3\\2x^2(6x-1)+3(6x-1)\\(6x-1)(2x^2+3)

Hence, the equation which shows the one way to determine the factors of provided equation by grouping is,

2x^2(6x-1)+3(6x-1)
