Answer:
d(x) = 175 - |175 - 25x|
Step-by-step explanation:
Suppose I plan to ride your bicycle from Portland Oregon to Seattle Washington and back to Portland.
Portland and Seattle are 175 miles apart. I plan to travel 25 miles every day.
If we consider the starting point i.e. Portland as the zero distance i.e. reference, then we can model the distance from Portland d(x) as
d(x) = 175 - |175 - 25x|
where x is the number of days into the ride. (Answer)
Answer:
A. 90 degrees clockwise rotation
Step-by-step explanation:
Of we have a coordinate axis (x,y), if this axis is rotated 90° clock wide, the resulting coordinate of the pre-image will be the coordinate (y -x). Note that the coordinates was swapped and then the new y coordinate negated.
Given the coordinate K(24, -15). If we rotate this clockwisely, first we swap the coordinate axis to have (-15, 24)
Them we will negate the new y coordinate axis to have;
K'(-15, -24)
Therefore the correct answer is 90° clockwise rotation.
Answer:
340 children, 210 adults.
Step-by-step explanation:

Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
The slope of the line containing the points is 28... we need the negative reciprocal of this for the slope of line perpendicular..
So the slope would be: choice B
