In simplifying the given expression, the error made was in Step 4. 7c - 41 is wrong. The correct answer should be -c - 59.
How to Simplify Expressions?In simplifying expressions, like the one given, first apply the distributive property to clear out the bracket.
Next is to combine like terms. In step 4, there was an error in the calculation while combining like terms.
-6c - 3c + 10c should give us -c NOT 7c.
Also, 3 - 12 - 50 should give us -59 not -41.
Therefore, the correct answer should be:
-c - 59.

The option A is showing the domain ans the range of the function F(x) as inverse of F(x).
What is inverse function?In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]{\displaystyle f^{-1}.}[/tex]
Here in the graph we can see that the option A has the clear range of the function.

Find the value of x in the parallelogram below.
Answers
Answer:
x = 25
y = 6
Step-by-step explanation:
In a parallelogram, opposite angles are equal.
2x and 50 are opposite angles,
2x = 50
Divide 2 on both sides,
x = 50 / 2
x = 25
In a parallelogram opposite sides are equal.
y + 5 and 11 are opposite sides,
y + 5 = 11
y = 11 - 5
y = 6
Answer:
x=25
y=6
Step-by-step explanation:
from the diagram,
2x= 50(opposite angles of a parallelogram)
2x= 50
dividing bothsides by 2
2x/2=50/2
x= 25
then,
y+5=11(opposite sides of a parallelogram)
y= 11-5
y= 6

A square has an area of 81 square inches. What is its perimeter?
Answers
Area of square = [tex]s^2[/tex] where, [tex]s[/tex] is the side length of the square.
[tex]81=s^2[/tex]
[tex]9=s[/tex]
s must be positive since it is a side length, so the negative root of 81 is rejected.
Perimeter= [tex]4s[/tex]
Perimeter= [tex]4(9)=36inches[/tex]
Step-by-step explanation:
In order to find the perimeter we need to find the length first ...
...Here, the area is already given ...
Area = 81 inches square
length = ?
Now....
( The formula of area is l × l )
[tex]area = {l}^{2} [/tex]
[tex]81 = {l}^{2} [/tex]
Now we should find square root of 81...
[tex]l = \sqrt{81} [/tex]
[tex]l \: = 9[/tex]
Now we find length so it's easy for us to find perimeter...
The formula of perimeter of square is 4l ..
= 4l
= 4 × 9
= 36 inches
hence the answer is 36 inches....

On the RHS, the 6's cancel:-
◆-0.5•6=-m
Multiply:-➪ [tex]\it{-3=-m}[/tex]

Answer:
m = 3
Step-by-step explanation:
⇒ -0.5 = - m/6
Divide both sides by -1.
⇒ -0.5/-1 = -m/(6 × -1)
⇒ 0.5 = m/6
Multiply both sides by 6.
⇒ 0.5 × 6 = m/6 × 6
⇒ m = 3
