Answer:
(a) 
(b) Domain:

(c) 
Step-by-step explanation:
Given
Solving (a): A function; l in terms of w
All we need to do is make l the subject in
Divide through by 2
Subtract w from both sides
Reorder
Solving (b): The graph
In (a), we have:
Since l and w are the dimensions of the fence, they can't be less than 1
So, the domain of the function can be

Answer: 14 people
Step-by-step explanation:
2/100 = 0.02
0.02 * 700 = 14
Answer:
(a) x = 3
(b) y = 6
(c) false/not true
(d) x = 5
Step-by-step explanation:
(A) 2 + x = 5 You would subtract the 2 from both sides which gives you x = 3
(B) 8y = 48 You would divide 8 from both sides which is 6 so y = 6
(C) 23 = 26 That is not true because 23 does not equal 26
(D) -7x - 3x + 2 = -8x - 8 First simplify the equation; -10x + 2 = -8x - 8. Next, you want to subtract 2 from both sides which gives us -10x = -8x - 10. Now you want to add 8x to both sides which is -2x = -10. And now you just divide -2 on both sides which gives us the answer 5. So, x = 5. I hope this helps.
