Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.
Answer:
A
Step-by-step explanation:
You know that the negative number with the largest magnitude is farthest to the left on the number line.
3/4 = 9/12
2/3 = 8/12
Then 3/4 > 2/3, so ...
-3/4 < -2/3
Answer:
a = d/2b - 2/b
Step-by-step explanation:
2ab+4=d
2ab=d-4
a= d/2b - 4/2b
<h2>a = d/2b - 2/b</h2>
Answer:
y =
x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 3x + 13 is in this form
with m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
y =
x + c ← is the partial equation
To find c substitute (6, 10) into the partial equation
10 = 2 + c ⇒ c = 10 - 2 = 8
y =
x + 8 ← equation of line
