In city W, the average cost for a gym membership is given by the equation y= 34.99x+49, where y is the total cost, in dollars, f
Anestetic [448]

The y - value is $83.99 when x = 1 which represents the total cost for 1 month of membership.

Explanation:

Given that in city W, the average cost for a gym membership is given by the equation y=34.99x+49 where  y is the total cost, in dollars, for x months of membership.

We need to determine the meaning of the y - value when x = 1.

<u>The value of y:</u>

Let us determine the value of y when x = 1

Thus, substituting x = 1 in the equation y=34.99x+49, we get,

y=34.99(1)+49

y=34.99+49

y=83.99

Thus, the y - value is $83.99 when x = 1 which represents the total cost for 1 month of membership.

The constant value of $16 will remain unchanged no matter the coefficient of x being the initial deposit

<h3>Linear equations</h3>

These are equations that has a leading degree of 2. The standard linear equation is expressed as:

y = mx + b

If Lauren wrote the equation y = 3x + 16 to represent the amount of money in a bank account that starts with $16 and increases by $3 each week, the constant value of $16 will remain unchanged no matter the coefficient of x being the initial deposit
