Answer:
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
Slope = m & y-intercept = b
x - 5y = 15
-5y = -x + 15
y =
so, slope = 1/5 ; (-5 , 7)
y -y1 = m(x -x1)
Answer:
37,500 m
Step-by-step explanation:
Given Usain bolt traveled 100m in 0.160 minutes
recall that
speed = distance travelled ÷ time taken
hence Usain Bolt's speed
= 100 m ÷ 0.160 min
= 625 meters per min
Now given that a car travels at the same speed for one hour.
recall 1 hour = 60 minutes.
Using the same formula as above
speed = distance traveled ÷ time taken
rearranging, we get
distance traveled = speed x time taken
we calculated the speed previously to be 625 m/min and we are given a time of 1 hour (i.e 60 min)
hence
distance traveled = speed x time taken
distance traveled = 625 m/min x 60 min = 37,500 m
Answer:
The set can be defined by listing all its elements, separated by commas and enclosed within braces. This is called the roster method.

Answer:
(a) 0.4
(b) a = 3
Step-by-step explanation:
(a) The area under the curve from x=4 to x=6 is 0.2 units high and 2 units wide, so is 0.2·2 = 0.4. (The area of a rectangle is the product of length and width.)
(b) The area is 0.2 and the height of the curve is 0.2, so the width of the region of concern is 0.2/0.2 = 1. (Again, area = height·width, or width = area/height.) 1 unit from the left end is found at X=3, so a = 3.
