Answer:
x - 18°F = 2°F
x = 20°F
Step-by-step explanation:
First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F
Your equation should look like this: x - 18°F = 2°F
Move the constant to the right hand side and change it's sign:
x = 2°F + 18°F
Add the numbers to get x = 20°F
Hope this helped!
Answer:
The slope is 
Step-by-step explanation:
Take the general equation of a straight line 
Here 
is the slope of the line.
So let's get the equation of the line in the question in the same form.
Add 
to both sides: 
Add 
to both sides: 
Divide by 
to get it into the general equation: 
Now compare it to the general equation to find the value of . The value of is the coefficient of 
which we can see is
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
They are both the second choices 1.)Transitive Property
2.)Reflective Property
Slope-intercept form:
y=mx+b
m=slope
b=y-intercept
We have this line: y=9x+3; a line parallel to this line (y=9x+3) will have the same slope; therefore m would be equal to 9 (m=9).
Data:
m=9
b=-2
y=mx+b
y=9x-2
Answer: y=9x-2
