S=Years Susanna has played the piano
p=Years Patrick has played the piano
The expression for this question would be s(2)+4=p
Hope this helps! :)
Answer:
solve the inequality in the form of w
Answer:
2
Step-by-step explanation:
So!
If the d (discriminant)
d > 0 Then 2 solutions
d = 0 Then 1 solution
d < 0 Then none
36 > 0 so 2 solutions
Y = x + 4
y = -2x - 2
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -6/3
x = -2
y = x + 4
y = -2 + 4
y = 2
solution is (-2,2)
