What is the 15th term of the arithmetic sequence described by this explicit formula?
an= 63+ (n-1)(-7)

- 35

Step-by-step explanation:

To find the 15 th term, substitute n = 15 into the formula, that is

= 63 + (15 - 1)(- 7) = 63 + (14 × - 7) = 63 - 98 = - 35

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

x=5

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
