Answer:
12x + y = 16
Step-by-step explanation:
Standard Form: Ax + By = C
Step 1: Write point-slope form
y + 4 = -12(x - 1)
Step 2: Find slope-intercept form
y + 4 = -12x + 12
y = -12x + 16
Step 3: Find standard form
12x + y = 16
7x2=14
So the answer would be 2
Answer:
an = 7·2^(n-1)
a10 = 3584
Step-by-step explanation:
(a) The terms of the sequence do not have a common difference, but they do have a common ratio. That ratio is 14/7 = 2. The general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
For a1=7 and r=2, the explicit formula is ...
an = 7·2^(n-1)
__
(b) The 10th term is ...
a10 = 7·2^(10 -1) = 7·512
a10 = 3584
