Answer:
So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of<em> 2 ounces lost per second.</em> Now that we know the slope, we can answer the questions
A. We can get the equation by finding the y int. (below) and writing it as y=-2x+68
B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2x5=10+58= <u><em>68 ounces at the beginning.
</em></u>
C. Since we have the formula and the slope, we just need to find when y hits 0. and that is: <em>After 34 seconds.</em>
Step-by-step explanation:
:D hope this helps
The slope is equal to: 5/2
The drop in temperature each hour is 2.528 degrees
<h3>How to determine how much did the temperature drop each hour?</h3>
The given parameters are:
Temperature drop = 15.8 degrees
Time = 6.25 hour
The temperature drop each hour is calculated as
Drop = Temperature drop/Time
So, we have
Drop = 15.8/6.25
Evaluate the quotient
Drop = 2.528
Hence, the drop in temperature each hour is 2.528 degrees

Answer:
(2, - 1 )
Step-by-step explanation:
3x - y = 7 → (1)
2x + 3y -= 1 → (2)
multiplying ( 1) by 3 and adding to (2) will eliminate y
9x - 3y = 21 → (30
add (2) and (3) to eliminate y
11x = 22 (divide both sides by 2 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
2(2) + 3y = 1
4 + 3y = 1 (subtract 4 from both sides )
3y = - 3 ( divide both sides by 3 )
y = - 1
solution = (2, - 1 )
