<em>x = 9</em>
<em>y = 0</em>
- Step-by-step explanation:
<em>y = -2x + 18 </em>
<em>4y - x + 9 = 0</em>
<em />
<em>4(-2x + 18) - x + 9 = 0</em>
<em>- 8x + 72 - x + 9 = 0</em>
<em>- 9x + 81 = 0</em>
<em>81 = 9x</em>
<em>x = 81 : 9</em>
<em>x = 9</em>
<em />
<em>y = - 2×9 + 18</em>
<em>y = - 18 + 18</em>
<em>y = 0</em>
Answer:
Since every square has the same length in sizes...
3 x 3 = 9cm
Answer: 9cm

As we know,

So, we can infer that :

Now, let's calculate the mass of gases in each case :
<h3>Case A : Hydrogen ~</h3>



or

<h3>Case B : Helium ~ </h3>



or

<h3>Case C : Nitrogen ~ </h3>



or

So, the arrangement of masses from least to greatest is :
- (1.) Hydrogen < (2.) Helium < (3.) Nitrogen
Equation of the line is y = 4x + 4
Step-by-step explanation:
- Step 1: Given that the line passes through (2,4) and (1,0). Equation in slope-intercept form is y = mx + b
- Step 2: Find slope, m using the formula m = (y2 - y1)/(x2 - x1)
⇒ m = (0 - 4)/(1 - 2) = -4/-1 = 4
- Step 3: Find the y-intercept.
⇒ b = 4
- Step 3: Substitute the values in the equation
⇒ y = 4x + 4
