Answer:
3 weeks
Step-by-step explanation:
money required=$200
money owned=$155
Money saved per week=$15
Time taken to earn remaining money=x
200-155=45=>money that needs to be saved
time it will take to get that money=45 divided by 15=3
=>3 weeks
(-1,1)
All you have to do is plug it in the equation:
(x,y)
For (-1,1)
1=2(-1)+1
Simplify:
1=-1 but you know that 1≠-1 so (-1,1) is not it
For (3,7)
7=2(3)+1
7=7
For (-3,-5)
-5=2(-3)+1
-5=-5
For (0,1)
1=2(0)+1
1=1
c^2 = a^2 + b^2. Hope this helps!
