Determine the yearly cost
To do this, we multiply the monthly subscription by 12



<em>Hence, the yearly servics cost is $59.88</em>
You find the x coordinates using x = -b/2a = -6/2(-1) = 3
Substitute 3 in the equation and find y
y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3
Vertex (3,-3)
Answer:
Both are <u>equal</u> to each other.
Step-by-step explanation:


y = -2/3x + 5
this is the slope intercept. -2/3 is the slope and 5 is where it intercepts the y axis.
hope this helps
