If y = 1.5x + 3, and x =7.2, what is the value of y?

y = 13.8

Step-by-step explanation:

Plug in 7.2 for x in the first equation.

y = 1.5x + 3

y = (1.5)(7.2) + 3

Simplify. First, multiply, then add (following PEMDAS).

y = (1.5)(7.2) + 3

y = (10.8) + 3

y = 13.8

13.8 is your answer for y.

y=13.8

Step-by-step explanation:

If we know x=7.2, we can substitute that into the equation, which results in the equation y=1.5*7.2+3.

We can multiply 1.5 by 7.2 to simplify the equation more.

1.5*7.2=10.8

Our equation is y=10.8+3.

To solve, we can now add 10.8+3, which is 13.8.

y=13.8

Hope this helps!

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
