Could you give Brainliest please???

Answer:

y = 2 - 1/2x

Step-by-step explanation:

So we are given the equation 3x + 6y = 12 and are ask to find y.

To find y you must isolate it first.

3x + 6y = 12

(Subtract 3x to isolate the y term)

6y = 12 - 3x

(Divide both sides by 6 to isolate the variable)

y = 2 - 3/6x

(Simplify)

y = 2 - 1/2x

And that is your answer since there is a second variable.

What is the result when 3/8x + 2 1/5 is subtracted from 3 1/2x - 4 1/10?<br><br> Don’t put a link.

Answer:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10

So we get:

2 1/4x - 6 3/10

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

$f\left(x\right)\:=x^3+2x^2-16x-32$

Let us determine the factors by solving

$\:\left0\right\:=x^3+2x^2-16x-32\:$

$\left(x+2\right)\left(x+4\right)\left(x-4\right)=0$

Using the zero factor principle:

if $ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0$

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

(x+2)

(x+4)

(x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

(x-2)
(x+6)

Sally has two pieces of fabric that are 128 inches long. She needs to cut each piece of fabric into multiple pieces that are 6 i

Alborosie

42 pieces. Add 128+128=256, then divide that by 6 which is 42.6, and you have 42 pieces (complete pieces, but if it doesn’t ask for complete pieces then your answer is 42.6)
