Answer: The total amount the water change was -28 gallons by the end of the week <u>OR</u> The total amount the water changed decreased 28 gallons by the end of the week. Depending on how you want to word it.
Hope this helps!
Step-by-step explanation:
<u>Create you equation:</u>
x = the total amount the water changed
d = the amount of days
x = -4d
<u />
<u>Insert the known information into the equation and solve:</u>
x = -4d
x = -4(7)
x = -28
Step-by-step explanation:
2x - 10y > -20
=> x - 5y > -10
or x - 5y +10 > 0
Answer:
(22) = 7
Step-by-step explanation:
The inverse function maps the output of the function back to its input
f(7) = 22 means when input is 7 the output is 22
The inverse maps the output 22 back to the input 7 , that is
(22) = 7
Answer:
Step-by-step explanation:
The equation is mx+b=y.
M=slope (in this case 5)
x=x coordinates
b=y intercept
y=y coordinates
For the x and y coordinates, I'll use (2,0).
5(2)+_=0
10+_=0.
In this case, we only have one awnser, -10. Since 10+(-10) are the only ways to equal 0.
Hope this helps,
