Answer: Triangles B and C
Step-by-step explanation: Because one side is divisible by 1,2,5,10 and the other side is divible by 1,3,9, etc
Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate.
To solve for j, cross multiply:
4 x 45 = 18 x j
180 = 18j
Divide both sides by 18:
j = 10
There are 3,600 seconds in one hour so if it expands at rate of 930 miles per second then 930 * 3600= 3,348,000 miles per hour
Answer:
The line passing through (-8, 10) and (-1, 4).
Step-by-step explanation:
Two lines are perpendicular if the product of their slopes is -1. The slope of the line in the picture is
, so we should find a line with slope of
.
Note that the slope of the line in the last option is
.
