The unit rate is: 8/3 gallons per hour
Step-by-step explanation:
Given
Time = 15 minutes
As the unit rate has to be calculated per hour so, time has to be converted into hours

Water leakage = 2/3 gallons

Hence,
The unit rate is: 8/3 gallons per hour

Answer:
a=6m
Step-by-step explanation:
X=2
y=149
————-
Solve 8x+15=7x+17
alternate angles are equal
x=2
Substitute 2 in 8x+15 =31
180-31=149
y=149
Angles on a straight line add up to 180
Please use " ^ " to denote exponentiation:
<span>f(x) = –(x + 8)^2 – 1
Find the first derivative: f '(x) = -2(x+8)(1)
Set this = to 0: -2(x+8) = 0
solve for x: x = -8
Divide the number line into subintervals based upon x=-8:
(-inf, -8) and (-8, inf)
Choose a test value for x from each interval, e. g., -10 from the first interval and 20 from the second.
Subst. this test value into the derivative, shown above.
If the result is + the function is incr on that interval; if - the fn. is decr.
