Hello there. =)
<span>Ann is grouping 38 rocks .she can put them into groups of 10 rocks or as single rocks. what are the different way Ann can group the rocks?

The equation y = 2x + 1 is the slope - intercept equation of the line.
The general form of the slope-intercept equation of the line is y = mx + b, where m is the slope and b is the y-intercept (i.e. the value of y-coordinate when the x-coordinate is zero).
Then you now know that the slope, m, of line j is 2 and the y-intercept is 4.
Answers:
a. slope = 3, as explainded above
b. Slope of any parallel to line J is the same slope of line J, i.e. 2.
The slope is a number that measures the inclination of the lines (rise/run) which is the same for parallel lines.
c. line k
m = 2 and point (3,7)
y - y1 = m(x - x1)
y - 7 = 2(x - 3)
y = 2x - 6 + 7
y = 2x + 1
d. line h
perpendicular => slope of line h = - 1 / slope of line j
slope of line h = - 1/2
point (8, 10) and y - y1 = -1/2 (x - x1) => y - 10 = -1/2 (x - 8)
y = -x/2 + 4 + 10 = -x/2 + 14
Answer:
<em>6.4 meters per second</em>
Step-by-step explanation:
<u>Rate of Change</u>
If two variables x and t are to be related as the rate x changes when t changes, it can be expressed as:
Hans takes a ride in the elevator down from the 86th floor to the first floor, a distance of x=320 meters in t=50 seconds. The rate of descent is
