g(x)=h(x)+k

(x^2-6)=(x^2+3)+k

Describe the steps that you would use to generate an expression equivalent to 8.1b+6.7a+2.5+7+.9a-2.8b
bija089 [108]

Explanation:

1. Identify the different constellations of variables. Here there are three:

  • b
  • a
  • (none)

2. Combine coefficients of each of the different variable constellations:

  (8.1 -2.8)b +(6.7 +0.9)a +(2.5 +7)

  5.3b +7.8a +9.5

3. Perform any other operations that might be required depending on the sort of equivalent wanted. For example, one could write ...

  5.3(b +(78/53)a) +9.5 . . . . . . . shows the weight of a relative to b
