Answer: 9
Step-by-step explanation:
1.) you first want to plug in your x= -2
2.) 2*-2^2=1
3.) Solve in order.
4.) 2*-2 = -4
5.) -4 * -2 (your power) = 8 , it is a negative two because x = -2 and where it lands in the order of operations that is how you solve.
6.) 8 + 1 = 9
7.) =9 .
Answer:
Step-by-step explanation:
10x+ 150=220 is the equation for the second plan you subtract 150 from 220 to get 70 and divide that by 10 and you get 7 which is the number of weeks it'll take
220/25=x
So for this one it'll take 8.8 weeks to get enough money and you divide 220 by the amount which is 25 to get 8.8 the number of weeks I'll take
I dont understand what the second one is asking so sorry dude but I think that's right
First differences are all 7.3. You don't need a graph to know that is a linear function.
