Answer:
c
Step-by-step explanation:
in c, one of the domains has 2 ranges so it is not a function
Answer:
There is no value of x to fit this requirement.
Step-by-step explanation:
The 2 perimeters in terms of x are:
4(x + 3) for the square and
2(x+1) + 2(x +4) for the rectangle
and these need to be equal so
we equate these 2 and solve for x:
4(x + 3) = 2(x+1) + 2(x +4)
4x + 12 = 2x + 2 + 2x + 8
4x + 12 = 4x + 10
4x - 4x = 10 - 12
0 = -2 which is of course absurd so there is no solution to this equation.
The equation of the value of the car over a year is 2357.14x + y = 33,000. Then the value of the car 4 years after it was purchased is $23571.43.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A new car is purchased for $33,000 and overtime its value depreciates by one half every 7 years.
Then the value of the car is given by the linear equation. Then the line is passing through (0, $33,000) and (7, $16,500). Then we have
Let y be the value of the car and x be the number of years. Then we have
Then the value of the car 4 years after it was purchased, to the nearest hundred dollars will be

The answer is c.
a. (2.2≠5.11) (2.2 is not equal to 5.11)
b. or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)
c. (5.11=5.11) (5.11 is equal to 5.11)
Therefore c is the answer
