GIVING BRAINLIEST! Solve for y: 3x - y = 14 Thank you~

1 answer:

8 0

To solve y, we need to make y the only value on the left hand side of the equation:

$3x - 3x - y = 14 \\ 3x - 3x - y = 14 - 3x \\ - y = 14 - 3x \\ y = - (14 - 3x) \\ y = - 14 + 3x$
Therefore the value of y = -14+3x.

Hope it helps!

13_,644 130,000 this # was rounded to nearest ten thousand list the possible digits that could go in the thousands place to make

Nady [450]

We have two rules in case of rounding off digits,

Rule 1:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.

Rule 2:

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

We are given the number 13_,644 which rounds off to 130,000.

Now as we can see the number is rounded down, so we can apply rule number 2 here.

If we place the digit 0, 1, 2, 3 or 4 then the number will round off to 130,000.

Answer: The possible digits that can go in thousands place are 0, 1, 2, 3 or 4.

3and 4 11 minus 2and one half

Olegator [25]

Answer: 19/22

Step-by-step explanation:

= 3 + 4/11 - 2 -1/2

Then, 3-2= 1

Next, 4/11 -1/2= ?

LCD of 4/11 and 1/2 and you would get this 8/22 - 11/22= 3/22

Finally, 1 - 3/22 = 19/22

Which is true about the completely simplified difference of the polynomials a3b + 9a2b2 − 4ab5 and a3b − 3a2b2 + ab5?

Mrrafil [7]

Answer:

The difference is a binomial with a degree of 6

Step-by-step explanation:

Given:

a^3b + 9a^2b^2 − 4ab^5 and a^3b − 3a^2b^2 + ab^5

Let A = a^3b + 9a^2b^2 - 4ab^5

B= a^3b - 3a^2b^2+ab^5

The difference between A and B is

A - B = a^3b + 9a^2b^2 - 4ab^5 - (a^3b - 3a^2b^2 + ab^5)

Open parenthesis

A - B= a^3b + 9a^2b^2 - 4ab^5 - a^3b + 3a^2b^2 - ab^5

= a^3b - a^3b + 9a^2b^2 + 3a^2b^2 - 4ab^5 - ab^5

= 12a^2b^2 - 5ab^5

The fist term 12a^2b^2 has 2+2=4 as a degree

The second term 5ab^5 has 1 +5 =6 as a degree

Therefore,

the answer is: The difference is a binomial with a degree of 6

Help me please for a test

sveta [45]

Answer: y = 24

Step-by-step explanation:

you need the pythagorean theorem(a^2 + b^2 = c^2)

so we have the hypotenuse so we plug in what we knowwhich is:

10^2 + b^2 = 26^2 -> 100 + b^2 = 676

then solve for b^2

b^2 = 576 -> $\sqrt{576}\\$ = 24
