Step-by-step explanation:
Answer:
A) The relationship is directly proportional; as temperature increases, volume increases in the same way.
Step-by-step explanation:
Charles's law states that at a constant pressure, the volume of fixed a mass of a gas is directly proportional to its absolute temperature or kelvin temperature.
This law explains the direct relationship between Volume of the gas and its Kelvin temperature. That is, as Temperature increases, the volume of the gas increases.
Thus, the correct statement is "The relationship is directly proportional; as temperature increases, volume increases in the same way".
<h3><u>The value of x is equal to -6.</u></h3><h3><u>The value of y is equal to 3.</u></h3>
8x + 2y = -42
4x + 7y = -3
In the first equation, subtract 8x from both sides.
2y = -42 - 8x
Divide all terms by 2.
y = -21 - 4x
Now that we have a value of y, we can plug it into the second equation to solve for x.
4x + 7(-21 - 4x) = -3
Distributive property.
4x - 147 - 28x = -3
Combine like terms.
-24x - 147 = -3
Add 147 to both sides.
-24x = 144
Divide both sides by -24.
x = -6
Now that we have a true value for x, we can plug it into either equation to solve for y.
8(-6) + 2y = -42
-48 + 2y = -42
Add 48 to both sides.
2y = 6
Divide both sides by 2.
y = 3
