Jill's answer is wrong because you add the powers when there are like bases. You don't multiply.

g(f(x)) = x
Yes, the functions are inverses.
Step-by-step explanation:
Hi there!
We're given:
[tex]f(x) = 8x-7[/tex]
[tex]g(x)=\displaystyle\frac{x+7}{8}[/tex]
To solve for g(f(x)), plug f(x) into g(x) as x:
[tex]g(f(x))=\displaystyle\frac{(8x-7)+7}{8}\\\\g(f(x))=\displaystyle\frac{8x-7+7}{8}\\\\g(f(x))=\displaystyle\frac{8x}{8}\\\\g(f(x))=x[/tex]
Because g(f(x)) = x, the two functions are inverses.

-8(5n - 2) - (n + 3) = 54
Answers
2. Your problem should now look like this: -40n+ 16 -(n+3)= 54
3. Next distribute the negative to (n+3).
4. After doing that the problem should look like this: -40n + 16 -n -3= 54
5. Combine like terms to get the problem to look like this: -41n + 13=54
6. Subtract 13 from both sides.
7. Now you are left with -41n=41
8. Divide by -41 to both sides.
9. Your answer should be n=-1

Answers
Answer:
51°
Step-by-step explanation:
We know that all angles in a triangle add up to 180°
We have one of them, 68° for now.
We also know the angle on the outside of the triangle that forms with one side being extended. That side is a straight line (180°)
Which means the interior angle there would be 180-119 = 61°
This means that we have 2 out of 3 angles now. Now we just add them up and subtract them from 180°.
180° - (68+61) = 51° is our final answer.
Let me know if that makes sense, or if you have any other questions.
Hope I helped! :)

Answer:
a) 3x^2 + x - 2
b) 28m
Step-by-step explanation:
a) Since the Area for a normal square is b*l (base x length)
Do the same with this (Using FOIL ig)
(3x - 2) * (x + 1)
3x^2 + 3x - 2x - 2
3x^2 + x - 2
b) Since it's asking us to find out what the number will be while x = 3m, just substitute 3 for every "x" in the answer we got for a
3(3)^2 + (3) - 2
3(9) + (3) - 2
27 + 3 - 2
30 - 2
28m
Therefore the actual area of this rectangle is 28m

2. Deon wants to find the perimeter of a square with side length 6m - 3. Write two expressions that represent the perimeter, including one expression in simplest form. Perimeter of a square- p = 4(s) or p = s + s + s + s
Answers
Step-by-step explanation:
The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
The expressions that represent the perimeter of the square are p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.
What is perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given:
The side of the square is 6m-3 unit.
And all the sides of the squares are equal.
And the perimeter p of the square is,
= the sum of all the sides.
p = 4 x one side.
p = 4(6m-3)
The above expression represents the perimeter of the given square.
Simplifying,
p = 24m - 12
This is the simplest form of the expression.
Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.
