Answer: y = 1
Step-by-step explanation:
9x + (3 x 1) = 12
Hey You!
132*42% = 55.44
132 - 55.44 = 76.56
So, the Millers paid $55.44 for gas and $76.56 for electricity.
I would convert -2pi / 3 to degrees first by multiplying by 180degrees / pi. It equals 120 degrees.
120 degrees is in quadrant II, which is 90 degrees plus 30 degrees. It is 60 degrees from the 180 degrees.
So the reference triangle you use is 60 degrees.
Cos60 = 0.5
sin60 = sqrt(3) /2
But in quadrant II the only trig ratio that's positive is sin; all others are negative.
So cos120 = -0.5
sin60 = sqrt(3) /2

Answer:
y < 3/2x - 5/2 or y < 3/2 x - 2.5
Step-by-step explanation:
3x -2y > 5
Solve for y
3x - 2y > 5 when solving a problem with an inequality sign, rewrite the problem and solve with an equal sign and add the equality at the end.
3x - 2y = 5
-2y = -3x + 5
y = -3/-2x+ 5/-2
y = 3/2x - 2 1/2
Now if you have to use the inequality sign, you will use < because the y term was negative and that will change the direction of the inequality sign.
So y < 3/2x - 5/2 or y < 3/2 x - 2.5
Source of magnetic force - Nail
Source electric force - battery cell
<h3>What is an electromagnet?</h3>
We know that the electromagnet is a type of magnet whose magnetic property depends on the interaction of the magnetic material with an electric field. We can see in the image that the nail which serves as the magnetic material is connected to a cell which is the source of the given electric current.
It the follows that the nail above is the source of the magnetic force because the coils of wire while the battery cell is the source of the electrical force.
