The first thing you should do in this case is to compose both functions:
f (x) = x + 7
g (x) = 1 / (x-13)
Making the composition
f (g (x)) = (1 / (x-13)) + 7
f (g (x)) = (7 (x-13) +1) / (x-13)
Answer:
The domain of the function is:
x other than 13
(option 4)
Answer:
Quadratic expression
Step-by-step explanation:
5x + 3x^2 − 7
Degree of expression = 2
So it is Quadratic expression
Answer:
235 bracelets
Step-by-step explanation:
Mai must spend $250 on wire and $5.30 per bracelet beads. Mai creates the expression.
We are given the equation:
5.3n+ 250 to represent the cost of making n bracelets.
The maximum number of bracelets Mai can make with a budget of $1500 Is calculated as:
$1500 = 5.3n+ 250
Collect like terms
1500 - 250 = 5.3n
1250 = 5.3n
n = 1250/5.3
n = 235.8490566 bracelets.
Bracelets are created as whole numbers and they can't be in decimal form.
Therefore, the maximum number of bracelets Mai can make with a budget of $1500 is 235 bracelets.
Answer:
6x-5 if x<5
Step-by-step explanation:
If x<5, then x-5<0.
If x-5 is negative, then |x-5)=-(x-5) or -x+5.
5x - |x - 5|
5x-(-x+5) provided x<5
5x+x-5 by distributive property
6x-5 combined liked terms
