Step-by-step explanation:
Use th egemotric shape that is where 2 lines meet
it would take about 6 weeks and you would both have $130
Step-by-step explanation:
it would take you 5 weeks to reach $130 and your sister 1 week to reach $130.
F(3)=-18
You just replace x for three for your equation and then use Ofer of operations to solve it.
So f(3)= 21+ 2(3)-5(3)^2
The exponent goes first: f(3)= 21+ 2(3)-5(9)
Next is multiplication: f(3)= 21+ 6-45
Now add: f(3)= 27-45
Finally subtract: f(3)= -18
Hope this helps!
I believe that the answer is 43. If you need any help with showing the work I'd be happy to explain in the comments :0 hope this helps!
