To get the slope of -2y+38x=38.
Let us convert to slope intercept form, that is y=mx+b
So, subtracting 38x from both sides, we get
-2y=-38x+38
Now, Divide by -2 on both sides, we get
y=(-38/-2)x+(38/-2)
y=19x-19
Slope, m=19
10y-50=-20
10y=30 (I added 50 to -50, then added 50 to -20)
y=3 (I divided 10y by 10 to get y then divided 30 by 10)
Reply to this with any questions or if you need more clarification and I would be more than happy to help.
820=P(1.05)^3
P=708.35
I'm sorry I don't know how explain but that is the answer to the problem; 708.35
Answer: ![\frac{2}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B35%7D)
Step-by-step explanation:
Given: The total number of ways of to choose 3 contestants out of 7 (including me and my friend)=35..................> Total outcomes.
Favorable outcomes = 2
Then the probability that me and my friend are both chosen =![\frac{\text{favorable outcomes }}{\text{Total outcomes}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bfavorable%20outcomes%20%7D%7D%7B%5Ctext%7BTotal%20outcomes%7D%7D)
Thus , the probability that me and my friend are both chosen =![\frac{2}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B35%7D)
Answer:
x = 8.8 or x = 44/5
Step-by-step explanation:
1) Multiply both sides of the equation by 4, and cancel out the 4 on the bottom of 3/4, this turns the equation into: 8x - 4 = 3x + 40
2) Move the x to the lefthand side and change the side, do the same for the constant (4), this turns the equation into: 8x - 3x = 40 + 4
3) Combine like terms, subtract 8x from 3x and add 40 to 4: 5x = 44
4) Divide both sides by 5, and your answer is 44/5 (or 8.8 when converted to a decimal)
