Answer: km
Step-by-step explanation:
Let in one day Ethan rollerbladed x km.
And, According to the question,
In each day he rollerbaded the same distance,
Thus, in d days, he rollerbladed = d × x = dx km
But, Again according to the question,
He rollerbladed a total of 623 km over d days.
⇒ d x = 623 km
⇒ x = 623 / d km
Thus, He rollerbladed in a day = km
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
x + y = 1 → (1)
2y - x = 8 → (2)
Adding the 2 equations term by term will eliminate the x- term
(x - x) + (y + 2y) = (1 + 8), that is
3y = 9 ( divide both sides by 3 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for y
Substituting y = 3 in (1)
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Solution is (- 2, 3 )

Answer:
B. 1/((x -1)(x -2))
Step-by-step explanation:
The vertical asymptotes at x=1 and x=2 tell you the denominator will have factors such that these values make it zero: (x -1)(x -2). That is sufficient to identify choice B as the correct answer.
Are there any other options besides A. {3x+2y=3}?
