which equation shows y+1/5=3x in standard form? A. -15x+5y=-1 B. -5x+15y=-1 C. -15x+5y=1 D. 15x+5y=-1
2 answers:
You always begin by the Given equation, which is in this case:
y+
= 3x
To remove the fraction, you multiply the whole equation by 5:
5y + 1 = 15x
Then, you move the "15x" the left-side of the equation, changing it's sign
-15x + 5y +1 = 0
You move the "1" to the right side, changing it's sign
-15x + 5y = -1
So the correct answer is A :)
Hope it helped! ^^

Step-by-step explanation:
Let the regresssion line be linear because of a constant amount of money coming in. Let y be the total amount of money in the box and x the weeks of adding to the box:
We know that he puts $20 in the box from his birthday and $4 every week for x weeks. Therefore the total amount of money will be:
