Answer:
The pattern is that, every time a 9 is added. This pattern continuous forever.
Step-by-step explanation:
9 X 1 = 9
9 X 2 = 18 (9+9)
9 X 3 = 27 (9+9+9)
Etc.
Answer:
simplified: 3x^2+7x+5y-4
Step-by-step explanation:
all you gotta do is you add -5x and 12x
First isolate y for each equation so that y = x^2 + 3 and y = 2x^2 + 2 now set those equal to eachother and solve for x,
x^2 + 3 = 2x^2 + 2
= √x^2 = <span>√1
x is +- 1
then plug in x for one of the original equations y = 1^2 + 3 = 4
x = +-1
y = 4</span>
