Answer:
(-1,-5/3)
Step-by-step explanation:
By substituting -1 for x into the equation and solving for y, the answer is -5/3 in which shows that (-1,-5/3) is a solution.
Answer:
- left: a, 0.4A; b, 0.4A; c, 0.4A; d, 0.4A; e, 0.8A
- right: a, 0.4A; b, 0.2A; c, 0.4A, d, 0.2A; e, 0.6A
Step-by-step explanation:
The currents into and out of a single device are the same. The sum of currents into and out of a junction are the same.
<u>Left Circuit</u>
The two branches at the bottom of the circuit are identical, so will have the same current. The current in each branch will be half the current shown coming from the battery:
a = b = c = d = (0.8 A)/2 = 0.4 A
The current at e into the battery will be the same as the current shown coming out of the battery:
e = 0.8 A
__
<u>Right Circuit</u>
0.6 A is the sum of the currents into the two branches. The current in the bottom branch is shown as 0.2 A, so the current in the top branch must be 0.4 A. That way, the currents total 0.6 A.
As before, the current throughout any given branch is the same, so ...
a = c = 0.4 A
b = d = 0.2 A
e = 0.6 A
Jorge did better on his test.
Step-by-step explanation:
It is difficult to say who scored better on the test because Jorge got less wrong but had less questions on his test, Ava got more wrong but has more questions but overall 17 out of 20 is a 85% when 20 out of 25 is 80%
Answer:
10. 48 degrees 11. Use explanation below. 12. 25 degrees 13.Use explanation below. 14. 63 degrees 15. Use explanation below. 16. 130.5 17. A. 48 degrees B. 90 degrees and C. 42 degrees 18. Explain
Step-by-step explanation:
10. All triangles angles add up to 180 degrees, so 100+32=132 and 180-132=48
11. Use the explanation above.
12. Using the rule above 88+57=145 and 180-145= 25
13. Use explanation above.
14. Add the two answers from 10 and 12. 48+25= 63
15. Use explanation above.
16. Using the triangle 180 degrees rule add 90 degrees (Angle a is a right angle which is always 90 degrees) to 40.5 degrees. 40.5 + 90= 130.5
17. You have angle A (48) angle B is a right angle aka 90 degrees and using the rule 90+ 48= 138 and 180-138= 42
18. I think you can explain it now (I hope)
Answer:
C. 3n+7=7+3n
Step-by-step explanation:
I got it right on my unit test! :)
Since the other person just got
it for points I decided
too answer
it myself you’re welcome!
