f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
Option A
The inches of snow fall during the month of January when the average temperature is 2°F is 17.747 inches
<em><u>Solution:</u></em>
Given that the equation of the line of best fit is:
y = -0.368x + 18.483
Where "y" is the total snowfall in her city
"x" is the average temperature
To find: Inches of snow fall during the month of January when the average temperature is 
Substitute x = 2 in given equation to find the total snowfall
y = -0.368x + 18.483
y = -0.368(2) + 18.483
y = -0.736 + 18.483
y = 17.747
Therefore inches of snow fall during the month of January when the average temperature is 2°F is 17.747 inches

Answer:
a=6
b=-14
Step-by-step explanation:
Answer:
x=-5/3
Step-by-step explanation:
ABD + DBC = ABC
Substitute the values
6x+9 + x+1 = 10x+15
Combine like terms
7x+10 = 10x+15
Subtract 7x from each side
7x-7x+10 = 10x-7x+15
10 = 3x+15
Subtract 15 from each side
10-15 = 3x+15-15
-5 =3x
Divide each side by 3
-5/3 =x
This will give us a negative value for DBC
DBC = -5/3 +3/3 = -2/3
We cannot have a negative value for an angle
Check the values given.
