The value of y would decrease if x increases and the sum stays the same.

If the value of x increases by 4 and the sum is constant or the same, the value of y will decrease. Ex: if x=1 increase by 4 so, 5+y=13 then y=8,if x increase by 4, 9+y=13, then y=4.

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50
Vsevolod [243]

Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

3.00 + 0.50 m = 9.50

Where m is the number of miles.

The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.

So, the correct statements are:

  • The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
  • Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Feel free to ask for more if needed or if you did not understand something.

Describe how to evaluate the expression 3^2 + (21 - 9) X 6÷2. Can someone help me out, please? I'm having trouble, and my teache
mylen [45]

Answer:

3^2+\left(21-9\right)\times \:6\div \:2=45

Step-by-step explanation:

Given the expression

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

Follow the PEMDAS order of operations

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

calculate within parentheses  \:(21-9)=12

=3^2+12\times \:6\div \:2

calculate exponents  3^2=9

=9+12\times \:6\div \:2

Multiply and divide (left to right)

=9+36

Add and subtract (left to right)  12\times \:\:6\div \:\:2=36

=45

Thus,

3^2+\left(21-9\right)\times \:6\div \:2=45
