B: the relationship is proportional
Answer:
the equation in slope intercept is y = -4.
ot your points and it is a straight line across..no slope.
Answer:
The sequence above is a geometric sequence
For an nth in a geometric sequence

where n is the number of terms
a is the first term
r is the common ratio
From the question
a = 45
r = 15 / 45
The explicit formula for the sequence is
U(n) = 45(1/3)^n-1
Hope this helps you
Answer:
x = 10
Step-by-step explanation:
First, distribute:

Next, subtract
from both sides:

(multiply
by 2 to get common denominator,
)

Next, subtract
from both sides:

(multiply
by 2 to get common denominator,
)
⇒ 
Next, multiply both sides by 10:

FInally, divide both sides by -1:
x = 10
