Answer:
(4, 9) is not a solution to 3(x + 2) = y.
Step-by-step explanation:
3(x + 2) = y
Substitute (4, 9) into the equation.
3(4 + 2) = 9

3(6) = 9
Multiply.
18 ≠ 9

Answer:
Step-by-step explanation:
(x+2)/2 = 0
x + 2 = 0
x = -2
(y - 3)/2 = 2
y - 3 = 4
y = 7
(-2, 7)
If two sides of a rectangle add up to 18cm and the area is 80 units squared then the length is 10cm, and the width is 8cm. If you add 10 and 8 together you get 18, and if you multiply those you get 80 units squared. Hope this helps!
