We use a system of equations to solve this. Since tri city sells 4 times it becomes 4x and solly company is x. Then we do 4x-x=96. 3x=96. x=32. We are not finished yet. We still have to multiply x by 4. x=128. Tri City sold 128 dishwashers.
Answer:
B: -13*
C: -2*
D: 8*
E: -11*
Step-by-step explanation:
math

is undefined where the denominator is zero. The domain is all values of x for which the function is defined.
The domain of f(x) is all real numbers except 13.
It will take 20 months for the cost to be same.
Step-by-step explanation:
Apartment A;
Security deposit = $1000
Each month cost = $1200
Let,
x be the number of months.
A(x) = 1000 + 1200x
Apartment B;
Security deposit = $1500
Each month cost = $1175
B(x) = 1500 + 1175x
The cost will be same when the functions are equal, therefore,
A(x) = B(x)

Dividing both sides by 25

It will take 20 months for the cost to be same.
