What is the value of x in y=3x-5 and 6x+3y=15

Mathematics

X=2

You first solve for y on the other equation 6x+3y=15 which will be: y=5-2x

Then you make it one equation: 3x-5=5-2x

Third step is add the -2x with the 3x which is will be 5x.

Fourth: your new equation will be 5x-5=5

Next u would add 5 plus which is 10

Lastly your new equation is 5x=10


I honestly hope this helps !!!!

What value of x is in the solution set of 3(x-4)greater than or equal to 5x+2
Gnesinka [82]

3(x-4)>= 5x+2

Distributing 3 on x-4

3(x)-3(4)>=5x+2

3x-12>=5x+2

Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides

-2x >=14

Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is

x<=-7

If n^-2 = 1/16, then n could be which of the following?
Zepler [3.9K]

Answer:

The correct choice is

\boxed{n=4}

Step-by-step explanation:

The given equation is

n^{-2}=\frac{1}{16}

We rewrite the left hand side of the equation as a power(a number to a given exponent.

n^{-2}=\frac{1}{4^2}

Recall that;

\frac{1}{a^m}=a^{-m}

We apply this property to obtain;

n^{-2}=4^{-2}

Since the exponents are the same, the bases are also the same.

Therefore n=4
