If you would like to solve the system of equations, you can calculate this using the following steps:
6x – 3y = 3
–2x + 6y = 14 /*3
_________
6x – 3y = 3
<span>–6x + 18y = 42
</span>_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3
<span>6x – 3y = 3
</span>6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2
(x, y) = (2, 3)
The correct result would be (2, 3).
Correct formula is y = kx, where k is the "constant of proportionality."
If y = 9 when x = 2, then 9 = k(2), or k = 9/2.
Then y = (9/2)x.
If x = 3, y = (9/2)(3) = 27/2 (answer)
Table:
x values: 5, 10, 15, 20, 25
y values: 7, 14, 21, 28, 35
Hello!
To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.
C = 2(36)π
C = 72π
Therefore, the circumference of the circle is 72π inches.
