Answer:
Equation: y = 8x + 56
After 5 minutes, the volume of the water was 96 gallons
Step-by-step explanation:
Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.
Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.
There are already 56 gallons of water in the tank, so b will be 56.
Plug in these values into the equation:
y = 8x + 56
So, the linear equation is y = 8x + 56
Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:
y = 8x + 56
y = 8(5) + 56
y = 40 + 56
y = 96
So, after 5 minutes, the volume of the water was 96 gallons
Total: 195 = x + (x+25)
195 - 25 = 2x
170 = 2x
85 = x
Therefore, there are 85 boys in 7th grade.
The answer will be 12 4/5
320/25 the you simplify by 5
64/5 ➗ by 5
12 4/5
Using the inverse function concept, the table that represents the inverse of the table given is table a.
<h3>How to find the inverse of a function of pairs (x,y)?</h3>
The inverse of the function is given by the set that contains point (y,x), that is, the coordinates are exchanged.
In the table given, we have points (0,0), (2,1) and (4,2), hence the inverse table has points (0,0), (1,2) and (2,4), which is table a.
