Answer:
5y-4x= -7 :
Slope = 
= 0.800
<em>x </em>- <em>intercept = </em>
= 1.75000
<em>y - intercept = - </em>
= -1.40000 <------both of these numbers a negative
----------------------------------------------
2y+4y = 14 :
<em>y = </em>
= 2.333
----------------------------------------------
<em>Hope this helped & good luck <333</em>
Answer: 2.5
Step-by-step explanation:
I believe 2.5 because If we take y/x we have 4,10 so I divide.
I drive 25 miles per day
divide the number of miles per day by the total miles to find how long it will take:
10,000 miles / 25 miles per day = 400 days
Without needing fancy formulas, we can conclude that after 10 years, half of the substance will be left. So, we can make our own formula:
amount remaining = 1 / 2^(years/10)
So, after 5 years
amount remaining = 1 / 2^(5/10)
amount remaining = 1 / 2^(.5)
amount remaining = 1 /
