im sorry... i dint mean to...umm....im sure that those r the right answers i used them for my test...and im sorry for cheating... i will..um not post any anwsers for the whole test again :)
To find the first four terms of the sequence represented by the expression 3n + 5, you need to substitute the values of n into the expression.
Start with the given expression: 3n + 5.
To find the term when n = 1, substitute n = 1 into the expression:
3(1) + 5 = 3 + 5 = 8.
So, the first term of the sequence is 8.
To find the term when n = 2, substitute n = 2 into the expression:
3(2) + 5 = 6 + 5 = 11.
So, the second term of the sequence is 11.
To find the term when n = 3, substitute n = 3 into the expression:
3(3) + 5 = 9 + 5 = 14.
So, the third term of the sequence is 14.
To find the term when n = 4, substitute n = 4 into the expression:
3(4) + 5 = 12 + 5 = 17.
So, the fourth term of the sequence is 17.
The options given are:
A) 3, 8, 14, 20
B) 8, 11, 14, 20
C) 3, 6, 9, 12
D) 0, 8, 11, 14
Comparing the four terms we found, we can see that option B) 8, 11, 14, 20 matches our results. Therefore, the correct answer is B) 8, 11, 14, 20.
For question 7,
The relationship between the total cost C(g) and the number of gallons purchased g is given by the expression C(g) = 2.19g.
In function notation, we use the letter f to represent a function. So, we can rewrite the expression as f(g) = 2.19g.
The options given are:
A) C(g) = -2.19g
B) g = 2.19C(g)
C) C(g) = g + 2.19
D) C(g) = 2.19g
Comparing the options with the given expression, we can see that option D) C(g) = 2.19g matches the given relationship correctly. Therefore, the correct answer is D) C(g) = 2.19g.
