9) n=7
10) y=66
11) w=9
12)g=42
13)f= -15
14) p=2
Answer:
y = 4
Step-by-step explanation:
equate these two equations, obtaining 2x+2 = x^2+3. Solving this for x, we get:
x^2 - 2x - 2 + 3 = 0, or x^2 - 2x + 1 = 0. This is equivalent to (x - 1)^2 = 0. There's a double root here: x = 1 and x = 1.
Since Y=2x+2, y = 2(1) + 2, or y = 4, when x = 1.
The y-coordinate of the solution is y = 4.
