The ratios are all proportional to 50/1.
Ratios are proportional when its cross products are equal.
a/b = c/d where ad = cb
100/2 is proportional to 50/1 because 100*1 = 2*50 ⇒ 100 = 100
150/3 is proportional to 50/1 because 150*1 = 3*50 ⇒ 150 = 150
175/3.5 is proportional to 50/1 because 175*1 = 3.5*50 ⇒175 = 175
200/4 is proportional to 50/1 because 200*1 = 4*50 ⇒ 200 = 200
Answer:
Option C
{-1,3,5}
Step-by-step explanation:
A mapping is a subset of ordered pair (x,y) where x belongs to first set and y belongs to second set.
Hence a mapping is a subset of cartesian product AXB.
Here A = {-2,1,3,5} and
B = {2,4,6,8}
Ordered pair given by the mapping is
(-2,1) (3,6) and (5,8)
In other words, -2 is mapped on to 1, 3 to 6 and 5 to 8
Domain = set of elements in the I set which are mapped
= {-1,3,5}
A line can be drawn by joining the plot of the two given points
- Please find attached the graph of the line created with MS Excel
- The equation of the line is <u>y = -x - 2</u>
Reason:
Given points on the line are (-5, 3) and (-1, -1)
- From the given points, the graph of the line can be plotted with MS Excel
The slope, <em>m</em>, of the line is given as follows
Therefore, we have;
The equation of the line in point and slope form is therefore;
y - 3 = -1·(x - (-5) = -x - 5
In slope and intercept form, we have;
y = -x - 5 + 3 = -x - 2
- The equation of the line in slope and intercept form is <u>y = -x - 2</u>
