Answer:
f(x) = -4x^2 +48x -129
Step-by-step explanation:
It usually works well to compute the square first. That is, simplify according to the order of operations.
f(x) = -4(x^2 -12x +36) +15
f(x) = -4x^2 +48x -144 +15
f(x) = -4x^2 +48x -129
Answer: 1,3,5
Step-by-step explanation:
Answer: the system has no solution
Step-by-step explanation: for a solution to occur the lines have to cross
The ordered pair (7,3) means there is an “x” value of 7, and a “y” value of 3 at said coordinate.
