How do I turn 5 — 3(х+1) — 2y — 3х + 2 into an y=mx+b form
1 answer:
Answer:
y = -3x + 2
Step-by-step explanation:
Ok so I assumed that you are setting this equal to 0 or there would be an equal sign in the equation. So basically you just want to gather like terms on each side so the y's on the left and the x's on the right. You then want to solve using algebra and you have your answer! I will add a picture to show my steps.

Step-by-step explanation:
Total number of toll-free area codes = 6
A complete number will be of the form:
800-abc-defg
Where abcdefg can be any 7 numbers from 0 to 9. This holds true for all the 6 area codes.
Finding the possible toll free numbers for one area code and multiplying that by 6 will give use the total number of toll free numbers for all 6 area codes.
Considering: 800-abc-defg
The first number "a" can take any digit from 0 to 9. So there are 10 possibilities for this place. Similarly, the second number can take any digit from 0 to 9, so there are 10 possibilities for this place as well and same goes for all the 7 numbers.
Since, there are 10 possibilities for each of the 7 places, according to the fundamental principle of counting, the total possible toll free numbers for one area code would be:
Possible toll free numbers for 1 area code = 10 x 10 x 10 x 10 x 10 x 10 x 10 =
Since, there are 6 toll-free are codes in total, the total number of toll-free numbers for all 6 area codes =
