Hey there!

Just do $\bold{PEMDAS}$

$\bold{Parentheses//Exponents//Multiplication//Division//Addition//Substraction}$
$\bold{First:Parentheses}$
$\bold{(3-1)=2}$
New $\bold{problem:-4(2)+2}$
Next we have to do: $\bold{multiplication}$ (since we DON'T have any $\bold{exponents}$ )
$\bold{-4(2)=-8}$
New $\bold{problem:-8+2}$
$\bold{Solve}$ that above $\uparrow$
$\boxed{\boxed{\bold{Answer:-6}}}$ $\checkmark$

Good luck on your assignment and enjoy your day!

(06.01) In the below system, solve for y in the first equation. x + 3y = 6 2x − y = 10 one thirdx + 2 negative one thirdx + 6 −x

NISA [10]

we have that

x + 3y = 6 -------> first equation

2x − y = 10

x + 3y = 6-----> substract x both sides

-x+x+3y=6-x

3y=6-x-----> divide by 3 both sides

y=(6-x) /3

y=2-(x/3)

y=-(x/3)+2

therefore

the answer is

negative one thirdx + 2

Solve the equation : 8+10^x=1008

Marizza181 [45]

Hi there.

I'm just going to put the answer for now. I might come back and edit my answer if I figure out how to solve this the long way.

All I did was figure out what exponent you raise 10 to.

10³ = 1000

So, we now have 8 + 10³ = 1008

Edit:

I did it on paper - here it is broken down.

8 + $10^{x}$ = 1008

Subtract 8 from both sides.

$10^{x}$ = 1000

We know that 10³ = 1000

<em>x</em> = 3

Solve for x<br>6x²+2x-12

dem82 [27]

Answer:

Step-by-step explanation:

Solving for x means you have to factor. First factor out the GCF of 2 to get:

$2(3x^2+x-6)$ and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:

1, 18

2, 9

3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:

$x=\frac{-2+/-\sqrt{2^2-4(6)(-12)} }{2(6)}$ and

$x=\frac{-2+/-\sqrt{4+288} }{12}$ and

$x=\frac{-2+/-\sqrt{292} }{12}$ and

$x=\frac{-2+/-\sqrt{4*73} }{12}$ and

$x=\frac{-2+/-2\sqrt{73} }{12}$ which finally simplifies to

$x=\frac{-1+/-\sqrt{73} }{6}$ No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!
