Answer:
-1/2
Step-by-step explanation:
First you use to the formula m=y2-y1/x2-x1 and then you get -5/10 or -1/2. (m= slope)
Answer:
what does this mean you just put random numbers right?
Step-by-step explanation:
Answer: blue triangle: 53 - red triangle: 17
Step-by-step explanation:
12+2+7\left(3\right)+7+5\left(3\right)-4
12+2+21+7+5\left(3\right)-4
12+2+21+7+15-4
53
3+3+6-5+3+7
For the second one:
Answer: The difference between subjective and objective writing is that subjective writing includes a person's feelings, while objective writing is not influenced by a person's emotions.
Answer:
<h2>B. 3,4 Volt</h2>
Step-by-step explanation:
Here we need to use Ohm's Law, because we have electric current, voltage and resistances. This law state: 
So, first we need to calculate the total resistance to then find the voltage. The resistances can be placed in two ways: in parallel, in series.
The pair 4 and 8 ohms are parallel, so we solve:


Which is, 
Now, this total resistance of parallels ones is placed in series with the 3 ohm resistance, in this case we just sum, because they are in series:

Now that we have the total resistance of the circuit, we use the Ohm's Law:

Therefore, the right answer is B.
