Answer:
d. 10
Step-by-step explanation:
9x + 3 = 30
9x = 27
x = 3
Then 3x + 1 = 3 * 3 + 1 = 10
Okay so you make your own kind of number, add the two number together. then graph the number on the chart verifying where its at . go from the origin and fine out where your number stands. then make sure your equations can prove that what number you picked and were you put them made the answer true
hope this helped!
Solution
Part A
The general form of the n-th term = a + (n-1)d
Here we are given the 8th term A8 = 28
, common difference (d) = 6
A8 = a + (n - 1) 6
28 = a + (8- 1)6
28 = a + 7*6
28 = a + 42
a = 28 - 42
a = -14
Part B
n-th term is 760. a = -14 and d = 6.
Plugging in the values in the general form, we get
760 = -14 + (n -1)6
760 = -14 + 6n - 6
760 = -20 + 6n
6n = 760 + 20
6n = 780
Dividing both sides by 6, we get
n = 780/6 = 130
The value of n is 130
The range is the y values so your answer is.
Range = 3, 7, 11
