Answer:
The cost of the carpet at Magic Carpet is: 90 + 9*(area of carpet)
The cost of carpet at Carpeteria is: 50 + 13*(area of carpet)
The algebraic expression for which the cost is the same is: 90 + 9*(area of carpet) = 50 + 13*(area of carpet)
The area of carpet for which the cost is the same is: 10 square yard
Step-by-step explanation:
6a) The cost for magic carpet:
This company charges a fixed fee and a price for each square yard of carpeting, therfore the expression for the cost is:
cost = 90 + 9*a
Where a is the area of carpet to be installed.
6)b) The cost for Capeteria:
This company also charges a fixed fee and a price for each square yard of carpeting, so the expression is:
cost = 50 + 13*a.
6) c) The algebraic expression for the cost to be the same in both stores:
90 + 9*a = 50 + 13*a
6) d) We need to solve the expression above for a:
50 + 13*a = 90 + 9*a
13*a - 9*a = 90 - 50
4*a = 40
a = 40/4 = 10

Step-by-step explanation:
the function g(x)-- -----------><span>I could model it as a second degree equation
</span>the roots are (view the table)
x1=2
x2=4
g(x)=(x-2)(x-4)
therefore f(x)=−3 sin(x − π) + 2 (x-2)(x-4)
using a graphical tool------ >see attached drawing The answer is the option <span>
A) f(x)</span>
A - the third number falls between the first two
B - the first number is smaller than the second
