Answer:
C. <u>Karma was given $60 for her birthday</u>
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
If we graph the equation given to us in the question we can see the following graph (attached below). If we then look at the y-intercept we can see that the function crosses the y-axis at a value of 60. Therefore we can safely say that the y-intercept means that <u>Karma was given $60 for her birthday</u>. Since the y-intercept represents an initial static (non-changing) value in the function.

Answer:
" the summation from n equals 1 to 8 of 1 plus 3 times n " ⇒ 3rd answer
Step-by-step explanation:
The sequence is : 4 , 7 , 10 , ........
∵ 7 - 4 = 3
∵ 10 - 7 = 3
∴ The sequence is an arithmetic sequence, where the first term is 4
and the constant difference is 3
∵ The rule of the arithmetic sequence is ,
where is the first term, d is the constant difference and
n is the position of the term in the sequence
∵
∵ d = 3
∴
∴
∴
The segma notation is:
∑ (1 + 3n)
It means <em>" the summation from n equals 1 to 8 of 1 plus 3 times n "</em>
