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)

Can you help me with 12-3(x+1)=30

inysia [295]

Greetings!

$12-3(x+1)=30$
Distribute the Parenthesis.
$12-3x-3=30$
Combine like terms.
$9-3x=30$
Add -9 to both sides.
$(15-3x)+(-9)=(30)+(-9)$
$-3x=21$
Divide both sides by -3.
$(-3x)/-3=(21)/-3$
The Answer Is:
$x=-7$

Hope this helps.
