Answer:
8
Step-by-step explanation:
Step 1: Set up equation
-1 = 7 - x
Step 2: Subtract 7 on both sides
-8 = -x
Step 3: Divide both sides by -1
x = 8
So 7 subtracted by 8 equals -1.
The formula used to find the length of a line segment is the same formula as the Pythagoras theorem.
We take CD as the hypotenuse of the right-angled triangle and the distance between the x-coordinates and y-coordinates as the length of two short sides.
We can write the formula as
CD =

CD =
So, with rational equations, we have three different cases. If the numerator has degree m and the denominator degree n, if m>n, the rational equation has an oblique(slant) asymptote. If m=n, the asymptote is the quotient of the leading coefficient of the numerator divided by the leading coefficient of the denominator. If m<n, the rational equation has an asymptote at 0. Since m>n in this problem, we must perform polynomial division.

Since the remainder tends to 0 as it approaches infinity, we have a slant asymptote at y=3x.
Answer: He drove 139 miles.
Step-by-step explanation:
0.98x + 20.95= 157.17 where x is the number of miles driven.
-20.95 =-20.95
0.98x = 136.22
x= 139
