You must add the graphs for this equation
Hello <u>156339</u>
Since we know the amount of money is always decreasing, then we should know to subtract by 35. Because 2.25 is the cost per meal and x is the number of meals, the total cost should be 2.25x, which is correct because y is the amount of money left over.
Our final equation would be:
<u><em>y = 35 - 2.25x</em></u>
:)
Answer:
A y+5 > -2
Step-by-step explanation:
We have an open circle at -7. An open circle means greater than
y >-7
We want to add 5 to each side since all of our inequalities have +5 on the left
y+5 > -7+5
y+5 > -2
Answer:
Step-by-step explanation:
Positive integers normally form an arithmetic sequence such that in this case the initial term is 1 and the common difference is 1.
The number of terms is 2018 and therefore n = 2018
Sn= n/2( 2a+ (n-1)d) where Sn is the sum of n terms, a is the first term and d is the common difference.
Substituting the unknowns with the values
we get Sn = 2018/2 (2 + (2017) 1)
= 2018/ 2 (2019)
= 4074342/2
= 2037171
Therefore the sum of the first 2018 positive integer is 2037171.
