Sin 30° equals 0.5 and as a fraction that would be 5/10 and 5/10 simplified is 1/2
<h3><u>The value of y is equal to 1.</u></h3>
7(y - 3) = 2(y - 9) + 2y
Distributive property.
7y - 21 = 2y - 18 + 2y
Combine like terms.
7y - 21 = 4y - 18
Subtract 4y from both sides.
3y - 21 = -18
Add 21 to both sides.
3y = 3
Divide both sides by 3.
y = 1
The dependent variable is the one on the Y (vertical) axis
The independent variable is the one on the X (horizontal) axis
OH OH OH
i just remembered, in 6th or 7th grade, my science teacher gave us a way to remember which is which.
DRY MIX
DRY - Dependent (Responding) is on the Y axis
MIX - Manipulated (Independent) is on the X axis
Hope this helps!
