D
Step-by-step explanation:
Answer:
s = 7 degrees
Step-by-step explanation:
All the angles have to add up to 180, so take 180 - 90 - 54 (the angles you know), and set them equal to 4s + 8. You get 36 = 4s + 8, subtract 8 from both sides, divide by 4, and you get that s = 7 degrees

Answer:
The answer is
<h2>y = - 5x - 9</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = - 5x + 27
Comparing it with the general equation above
Slope = - 5
Since the lines are parallel their slope are also the same
Slope of parallel line = - 5
So the equation of the line using point
(-2,1) and slope - 5 is
y - 1 = - 5( x + 2)
y - 1 = - 5x - 10
y = - 5x - 10 + 1
We have the final answer as
<h3>y = - 5x - 9</h3>

Answer:
≈ $138
Step-by-step explanation:
let h be heating bill and t be average outdoor temperature
Given h varies inversely with t then the equation relating them is
h = ← k is the constant of variation
To find k use the condition h = 190 and t = 40 , then
190 = ( multiply both sides by 40 )
7600 = k
h = ← equation of variation
When t = 55 , then
h = ≈ 138.1818
That is monthly heating bill is approximately $138 ( to nearest whole number )
