Answer:
the formula is a_n = 6n - 5
Step-by-step explanation:
The formula is
Given that
{1, 7, 13, 19, 25, . . . }
The difference between the numbers is
7 - 1 = 6
13 -7 = 6
19 - 13 = 6
a = 1
d = 6
Now the formula is
a_n = a + (n - 1)d
= 1 + (n - 1)6
= 1 + 6n - 6
= 6n - 5
So, the formula is a_n = 6n - 5
Answer:
(3,0)
Step-by-step explanation:
We know that x intercepts is when the graph crosses the x-axis. Thus, all x intercepts have a y value of 0. (x, 0)
Therefore, we can set y to 0 to see when the graph equals y=0 or the x-axis.
2(0)-4x=-12
-4x=-12
x=3
2 = coefficient
e = variable
- = operation
f = variable
2e = 2 × e
f subtracted from the product of two and e
