Remember that a parallel line has the same slope...
So we already know the slope of the line containing point C is -4.

Using point slope equation, we can do...

y-y₁=m(x-x₁)
y-7= -4(x-4)
y-7- -4x+16
*Add seven to both sides...* y=-4x+23

There is you answer... hope this helps!

If a line is parallel to another line, both lines have the same slope. The slope of the line is -4, which means the slope of the parallel line would be -4.
Parallel lines never intersect, which means the y-intercept of the parallel line cannot be 5. The y-intercept of the parallel line is when x = 0. You know that one of the points of the new, parallel line is (4,7). So what happens if you use the slope to find the y-intercept? So you can take the point (4,7) and subtract 4 from the x-coordinate and add 16 to the y-coordinate (Remember, this is the slope because the change in y is 16, and the change in x is -4, making the slope -4). When you do this, then you get that the y-intercept is 23. Therefore, the equation for the line is y = -4x + 23.

To answer this problem, the utilization of the provided formula is of utmost importance.

The formula to be used would be for the combination with no repetition since it is what is asked and possibly happens when involving the products mentioned in the problem. The formula would be

------------- n = number of things to choose from
(n - r)! r! r = number of things needed to form

the symbol ! is called a factorial function which replaces the sequence of multiplying a number in a descending order.

lets substitute and solve

Karo-lina-s [1.5K]

Answer: 700 miles.

Step-by-step explanation:

1. You know that 23% of the total distance of the flight from Albuquerque New Mexico to Austin Texas is 161 miles.

2. Then, keeping that information on mind, you can calculate the total distance of the flight (which you call $x$ ) as following:
