Answer:
-148
Step-by-step explanation:
Hello!
We can evaluate by plugging in -3 for x, and -7 for y in the expression [tex]3x^3 - 2x^2 + 7y[/tex]
Evaluate
- [tex]3x^3 - 2x^2 + 7y \text{ for x=-3, and y=-7}[/tex]
- [tex]3(-3)^3 - 2(-3)^2 + 7(-7)[/tex]
- [tex]3(-27) - 2(9) - 49[/tex]
- [tex]-81 - 18 - 49[/tex]
- [tex]-148[/tex]
The evaluated value is -148.
