Answer:
No solutions.
Step-by-step explanation:
-2x - y = 1
-4x - 2y = -1 Multiply the first equation By -2:
4x + 2y = -2 Adding:
0 = -3
which is absurd so there are no solutions.

Answer:
Therefore d = 100 is a solution of the given equation.
A question that solving this problem could answer is "what is the range of d"
d < 171.43
Step-by-step explanation:
i) the given equation is 10 - 0.035d > 4
ii) if d = 100 then 10 - (0.035
100) = 10 - 3.5 = 6.5 > 4
Therefore d = 100 is a solution of the given equation.
A question that solving this problem could answer is "what is the range of d"
10 - 0.035d > 4
therefore -0.035d > 4 - 10
therefore -0.035d > -6
therefore 0.0035d < 6
therefore d < 6 / 0.035
d < 171.43
That is a 180 degree angle (the straight line) and one angle is 78, so you subtract 78 from 180
So the angle would be 102 degrees
