Answer:
<h2>R-{5}</h2>
Step-by-step explanation:
f(x)=x²-25=(x-5)(x+5)
g(x)=x-5
(f/g)(x)=<em>(x-5)</em>(x+5)/<em>(x-5)</em>=x+5; for x≠5
D=R-{5}
Answer: 0.4207
Step-by-step explanation:
Let 
be the sample mean area.
Given: Population mean : 
sq. feet
Standard deviation: 
sq. feet
Sample size : n= 10
The probability that the sample mean area is 
or less if the manufacturer’s claim is true.
Required probability = 0.4207
<span>The table must show:
Time (minutes) number of gallons remaining
X y
0 Yo
1 Yo – 1.5
2 Yo – 2*1.5
3 Yo – 3*1.5
4 Yo – 4*1.5
And the equation will be ; Y = Yo – 1.5 x, where Yo is the initial amount of water in the bathtub.</span>
Answer is :Y is the easiest first using second equation . Ill show you steps below why . If you want to see the steps .
2x+4y=26
3x+y = 9
So first solve second equation
3x+y=9
Y= -3x+9
Now plug into first equation
2x+4y=26
2x+4(-3x+9)=26
2x-12x+36=26
-10x+36=26
-10x= 26-36
-10x= -10
X=1
So now solve for y in second equation
Y= -3x+9
Y= -3(1)+9
Y= -3+9
Y= 6
So if you were to be asked answer in point (1,6).
