Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx

Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5

Then plug K value into equation
Y=6.5X

Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.

Check:
X=50

Y=6.5x50
Y=320

Use the Echelon Method<br> 1. Solve<br> x + 3y = 7<br> 3x + 4y = 11
Ludmilka [50]

Answer:

x = 1     y = 2

Step-by-step explanation:

x + 3y = 7

- Subtract x from both sides.

3y = -x + 7

- Divide both sides by 3 to isolate the variable.

y = -1/3x + 7/3

- Plug the value of y into the other equation.

3x + 4(-1/3x + 7/3) = 11

3x - 4/3x + 28/3 = 11

- Add like terms.

5/3x + 28/3 = 11

5/3x = 5/3

x = 1

- Plug the value of x into the equation.

x + 3y = 7

(1) + 3y = 7

3y = 6

y = 2

Factor the trinomial:<br><br> 2x^2+13x+21
tankabanditka [31]

Answer:

(2x + 7) \times (x + 3)

Step-by-step explanation:

{2x}^{2}  + 13x + 21

{2x}^{2}  + 7x + 6x + 21

x \times (2x + 7) + 3(2x + 7)

= (2x + 7) \times (x +  3)

What is the solution to the problem expressed to the correct number of significant figures? 15. 11 (142 × 16. 5) = ? A. 2,358 B.
olchik [2.2K]

The solution to the problem expressed  2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

15.11+(142\times16.5)

First we have to multiply the given digits as per rule.

=15.11+2343

Now we will add both the digits, we get

=2358.11

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.
