Covert standard form to slope-intercept form
4x + 7y + 3 = 0
7y = -4x - 3
y = (-4/7)x - 3/7 so the slope of this line is -4/7
The slope perpendicular to this is - 1 (-4/7) = 7/4
The required line has equation:-
y - 1 = (7/4)(x - (-2))
y - 1 = (7/4)x + 14/4
y = (7/4)x + 18/4 That is the answer in slope intercept form
Multiply through by 4
4y = 7x + 18
7x - 4y = 18 in Standard form Answer
In this question, we're trying to find how many hours Mike had the bike for.
We know that 13 dollars as a flat rate.
We also know that they charge 13 dollars and hour.
Mike paid a total of 67 dollars for the bike.
Lets represent this as an equation:
67 = 9x + 13
x = hours the bike was rented
Solve for x:
67 = 9x + 13
Subtract 13 from both sides
54 = 9x
Divide both sides by 9
6 = x
This means that Mike rented the bike for 6 hours.
Answer:
6 hours
The answer for this question is B. Let me know
Given:
The function f(x) describes the amount of money, in dollars, the club will earn for wrapping x presents.

To find:
The f(658).
Solution:
We have,

Substitute x=658 to find the value of f(658).


It means, the club will earn $1974 for wrapping 658 presents.
Therefore,
