Answer:
Step-by-step explanation: 4
Answer:
(5, 11) and (2, 2)
Step-by-step explanation:
y = (x-2)² + 2
y + 4 = 3x
(x-2)² + 2 + 4 = 3x
x² - 4x + 4 + 6 = 3x
x² - 7x + 10 = 0
(x - 5)(x - 2) = 0
x - 5 = 0, x = 5
x - 2 = 0, x = 2
y = (5-2)² + 2 = 11
(5, 11)
y = (2-2)² + 2 = 2
(2, 2)
(B)
Step-by-step explanation:
Rewrite the equations into their standard forms. The first one can be rewritten as
and the 2nd can be rewritten as
Solving this system either by substitution or elimination, we get
If you add x + y, you'll get a negative number.
