Answer:
the slope is negative 1 because everytime the line goes down 1 it goes to the right 1
94.8
First, a 42% reduction can be seen as multiplying by 0.58.
Next, simply set up the expression x(0.58) = 55 and then solve for x
Answer:
The Area is 25
Step-by-step explanation:
You will need distance formula for this questions
for AD, (0,4) and (4,7)
The formula is here
which gives you
for AB
(0,4),(3,0)
The answer will be 5*5, which is 25
9514 1404 393
Answer:
g^-1(x) = 1/(x+2)
Step-by-step explanation:
To find the inverse of the function ...
y = g(x)
swap the variables and solve for y.
x = g(y)
x = 1/y -2 . . . . . . . use the given g(x)
x +2 = 1/y . . . . . . . add 2
y(x +2) = 1 . . . . . . multiply by y
y = 1/(x +2) . . . . . divide by the coefficient of x
The inverse function is ...

<em>Additional comment</em>
Please observe that when the fraction is typeset, as in the boxed answer, the fraction bar serves as a grouping symbol. It shows you that the denominator is the sum x+2.
When the same expression is written in plain text, only the first item after the division symbol (/ or ÷) is considered to be in the denominator. That is, 1/x+2 = (1/x)+2. The presence or absence of a (space) has no bearing on the correct interpretation of the expression. Only parentheses will serve as a grouping symbol in plain text expressions.
g^-1(x) = 1/(x+2)
Solution:
1) Gather like terms
(3z-43z+2z)
2) Simplify
-38z-4+5
3) Simplify
-38z+1
Done!
