Answer:
-3
Step-by-step explanation:
slope formula is y2-y1 over x2-x1
if we plug in the values and solve, that gets you -3.
Remember The domain is always the left side of the relation. The range is always in the right.
Answer is C
They are the same in length
Answer: Opposite
Detailed Explanation:
If both pairs of Opposite sides of a Quadrilateral are equal, then it is a Parallelogram. These are the basic properties of a Parallelogram.
Answer:
C) 80 milliamperes
Step-by-step explanation:
The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:
Here, is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes( amperes) current flow through the circuit. Using these values we can find the value of proportionality constant. i.e.
Using this value, we can establish the relation between I and V as:
Now, we need to calculate value current (I) if voltage is equal to 4 volts. Substituting V = 4 in above equation, we get:
Thus, the value of current will be 80 milliamperes
