The piecewise function, d, represents one of Kelli's Saturday training runs and models her distance from home, d(t), in miles as a function of time, t, in minutes since she left home How many miles is Kelli from home when she is 90 minutes into her run?

because its not ur topic and its not for is for homework not that.

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
