Answer:

Step-by-step explanation:

You would just do the opposite. Instead of multiplying the .43 by the original you divide the product by .43 to get 46.5. 46.5 rounded is 47.

X=29 and y=10

You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.

HELP ITS URGENT please

stich3 [128]

The correct answer is D.

A function cannot have an x-value that corresponds to more than one y-value.
In this table, the x-value '8' corresponds to two separate y-values; 8 and 5, making it invalid as a function.

Find the constant of proportionality and unit rate for the data in the table. Then write the equation to represent the relations

Hatshy [7]

You should set up an X and Y table. Make time X and Distance Y. (the table is like a cross: on the left top put x and left top put y. Then under the line list the x and y numbers given in order.) Then find the "slope" which is y/x (rise over run) then you get the increase rate of 45 mph. The relation between them would be D=45t
