Y=-x-13, they have the same slope but different y intercepts which mean they are parallel, and when graphed, the equation goes through (-9,-4). hope this helps :)
5x^2+10x
factorise 5 and 10 first
then factorise the x
so 5x(x+2)
completed :))
hope this helped :)
Answer:
The each have to place 2 subscriptions
Step-by-step explanation:
Adriana
E (earnings) = 6 + 2*x where x is the number of subscriptions
Sophie
E (earnings) = 4 + 3x
For them to earn the same amount, their right sides must be equated.
4 + 3x = 6 + 2x Subtract 2x from both sides
4 + 3x - 2x = 6+ 2x - 2x Combine
4 + x = 6 Subtract 4 from both sides
4 - 4 + x = 6 - 4
x = 2
