You're adding 7 each time.
You are looking for the GCF or greatest common factor of 15 and 20 a way to do the is the upside down cake method.
Answer:
Linear equations use one or more variables where one variable is dependent on the other. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit
Let x represent the total number of chocolate cups and y represent the total number of vanilla cups Beth buys.
She needs a total of 24 ice cream cups. So, the equation can be written as:

The number of chocolate cups she needs are twice as compared to vanilla, so we can write the equation as:
Case 1: Only constraint
2 would be met if 9 vanilla cups and 18 chocolate cups were purchased.
This is because the number of chocolate cups are double as compared to vanilla cups but the total number of cups in this case is not 24. So constraint 1 is not met.
Case 2: Only constraint
1 would be met if 6 vanilla cups and 18 chocolate cups were purchased.
This is because the total number of cups in this case is 24 but the chocolate cups are three times as compared to the vanilla cups. So the constrain 2 is not met in this case.
The limit of a function is the value that a function approaches as that function's inputs get closer and closer to some number.
The question asks us to estimate from the table:

To find the limit of g(x) as x tends to -2, we need to check the trend of the function as we head towards -2 from both negative and positive infinity.
From negative infinity, the closest value we can get to before -2 is -2.001 according to the values given in the table. The value of g(x) from the table is:

From positive infinity, the closest value we can get to before -2 is -1.999 according to the values given in the table. The value of g(x) from the table is:

From the options, the closest estimate for the limit is 8.03.
The correct option is the SECOND OPTION.
