Answer:
Let F = customer's fare (in dollars)
Let d = distance traveled (in miles)
Given:
- Base fee = $5
- Charge per mile = $2 per mile
Creating an equation from given information:
F = 2d + 5
This is a linear equation, with slope of 2 and y-intercept of (0, 5)

Answer:
4
Step-by-step explanation:
-4x +6x +12 = 20
2x + 12 = 20
2x = 8
x = 4
So, first you must find the remaining angle measure. To do this add 25 and 90 then subtract from 180. The remaining angle measure is 65 degrees.
Next, use tangent, cosine, or sine to find the remaining side lengths.
I used sine of 25 which is opposite of hypo. which is sine 25 = y/43.
Multiply both side by 43 and you get y=18.17
Do the same to find x, but use the sine of 65, and you get sine 65 = x/43.
Multiply both sides by 43 and you get x=38.97
Hope this helped!
Answer:
-9n
Step-by-step explanation:
3n(5 + 3n - 8 - 3n)
First we combine the like terms inside the parenthesis:
3n(-3)
Because 5 -8 = -3 and 3n - 3n = 0
Now we multiply:
-9n
because 3n × -3 = - 9n
So the answer is -9n
