A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system.
Answer:
- 12x² + 9x + 9
Step-by-step explanation:
(- 10x² + 2) + (- 2x² + 9x + 7 ) ← remove parenthesis
= - 10x² + 2 - 2x² + 9x + 7 ← collect like terms
= - 12x² + 9x + 9

Answer:
(d) all real numbers greater than or equal to -1
Step-by-step explanation:
The y-value of the vertex at (3, -1) is the minimum of the function. All y-values equal to or greater than -1 are in the range of the function.
y ≥ -1
