Answer:
Answers are (r,0) and (0,s)
Step-by-step explanation:
Given that in a rectangle ABCD, one vertex is the origin (0,0) A
The opposite vertex C is having coordinates as (r,s)
Since a rectangle has angle 90 we have x axis as one side and y axis as other side.
Length = r and width =s (since coordinates of C are (r,s))
Hence other coordinate B on x axis would be = (r,0)
and D on y axis = (0,s)
Answers are (r,0) and (0,s)
Answer:
X+ 7 = 21 - 7 - 7x = 14
Step-by-step explanation:
replace x values and y values with the answer choices.


since the coordinate pair
it is safe to assume that d will be the correct answer.
use the graph to confirm that the solution is (1,0)
the blue line intersects at (1,0), so the solution for the system of equations is (1,0)
Answer:
1. 0.75 cm to 1 km
4. 0.3 mm to 40 m
Step-by-step explanation:
we have the scale

<u><em>Verify each case</em></u>
case 1) 0.75 cm to 1 km

therefore
The scale is equivalent to the given value
case 2) 1 cm to 12 km


therefore
The scale is not equivalent to the given value
case 3) 6 mm to 2 km
Remember that
1 cm= 10 mm
1 mm=0.1 cm
we have


therefore
The scale is not equivalent to the given value
case 4) 0.3 mm to 40 m
Remember that
1 cm= 10 mm -----> 1 mm=0.1 cm
1 km=1,000 m ----> 1 m=0.001 km
we have


therefore
The scale is equivalent to the given value
case 4) 1 inch to 7.62 km
Remember that
1 in= 2.54 cm
we have


therefore
The scale is not equivalent to the given value
It will travel 7.5 cm a revolution and 7.5 x 3 wound = your answer i believe
